I'm using rundll32 url.dll,FileProtocolHandler my_file.dotx to open files under Windows.
It works fine with .docx documents, but when I try it with .dotx documents (template documents), it creates a new .docx based on the template.
Just as the normal behavior in the windows explorer : when you double-click on a .dotx template file, it creates a new .docx file based on it. If you want to open the real .dotx file, you have to right-click on it and select "open" instead of "new".
Question is: how to do the same with rundll32? Is there an option in the command to force the opening of the underlying template instead of creating a new document?
Edit: I need a way to do it without C functions, just plain text, in the command line (I'm using Java to do it).
Maybe you can wrap a simple C program around ShellExecute, passing the verb OPEN.
ShellExecute(NULL, TEXT("open"),
TEXT("rundll32.exe"), TEXT("url.dll,FileProtocolHandler pathToGadget"),
NULL, SW_SHOWNORMAL);
I found this example here.
edit:
Since you're doing this in Java - you could try a JNI wrapping of the ShellExceute function like this (from the example I found on The Wannabe Java Rockstar and butchered)
public static boolean execute(String file, String parameters) {
Function shellExecute =
Shell32.getInstance().getFunction(SHELL_EXECUTE.toString());
Int32 ret = new Int32();
shellExecute.invoke(ret, // return value
new Parameter[] {
new Handle(), // hWnd
new Str("open"), // lpOperation
new Str(file), // lpFile
new Str(parameters), // lpParameters
new Str(), // lpDirectory
new Int32(1) // nShowCmd
});
if(ret.getValue() <= 32) {
System.err.println("could not execute ShellExecute: " +
file + ". Return: " + ret.getValue());
}
return (ret.getValue() > 32);
}
public static void main(String[] args) {
ShellExecute.execute("rundll32.exe","url.dll,FileProtocolHandler pathToGadget" );
}

I have a tree list which will open a specific html file when I click at a node. I try loading my html into a Jeditorpanel but it can't seem to work.
Here's my code from main file:
private void treeItemMouseClicked(java.awt.event.MouseEvent evt) {
DefaultMutableTreeNode selectedNode = (DefaultMutableTreeNode) treeItem.getSelectionPath().getLastPathComponent();
String checkLeaf = selectedNode.getUserObject().toString();
if (checkLeaf == "Java Turtorial 1") {
String htmlURL = "/htmlFILE/javaTurtorial1.html";
new displayHTML(htmlURL).setVisible(true);
}
}
Where I wanna display it:
public displayHTML(String htmlURL) {
initComponents();
try {
//Display html file
editorHTML.setPage(htmlURL);
} catch (IOException ex) {
Logger.getLogger(displayHTML.class.getName()).log(Level.SEVERE, null, ex);
}
}
My files:
One simple way to render HTML with JEditorPane is using it's setText method:
JEditorPane editorPane =...
editorPane.setContentType( "text/html" );
editorPane.setText( "<html><body><h1>I'm an html to render</h1></body></html>" );
Note that only certain HTML pages (relatively simple ones) can be rendered with this JEditoPane, if you need something more complicated you'll have to use thirdparty components
Based on OP's comment, I'm adding an update to the answer:
Update
Since the HTMLs that you're trying to load are files inside the JAR, you should read the file into some string variable and use the aforementioned method setText
Note that you shouldn't use java.io.File because it used to identify resources at the filesystem, and you're trying to access something inside the artifact:
Reading the resource like this can be done with the following construction:
InputStream is = getClass().getResourceAsStream("/htmls/myhtml.html");
// and then read with the help of variety of ways, depending on Java Version of your choice and by the availaility by auxiliary thirdparties
// here is the most simple way IMO for Java 9+
String htmlString = new String(input.readAllBytes(), StandardCharsets.UTF_8);
Read Here about many different ways to read InputStream into String
I am hoping that someone can help me here. I am using the yCad library to read a number of dxf files and output a composite model, to dxf format.
The initial process of reading the file is complete. However, when I save the file it is saved without the model.
Here is an example of the code used to save the dxf file
public static boolean SaveDxf(String outputPath, String fileName, Yxxf model)
{
try
{
model.iohandler = new YutilIOHandler();
model.ioname = new YutilIOHandlerName(fileName);
model.ioname.dstfile = outputPath + "\\" + fileName + ".dxf";
YdxfPutHandler handler = new YdxfPutHandler();
handler.commandPutMainStart(model.iohandler, model);
return true;
}
catch(Exception ex)
{
System.out.println("failed to save dxf file: " + ex.getMessage());
return false;
}
}
When the file is viewed from an editor an error is reported stating the model is empty.
The error occurs even when a dxf file is read and then saved with no manipulation.
I have resolved this issue.
The resolution required a modification to the version of the YCad library that I was using due the following selection.
if (ent instanceof YxxfEntLine)
{
YdxfPutEntLine.put(putbfr, (YxxfEntLine)ent);
}
NOTE: This may have been due to an out of date version of the library.
The method was modified to include all required types.
else if(ent instanceof YxxfEntPolyline)
{
YdxfPutPolyline.put(putbfr, (YxxfEntPolyline)ent);
}
A number of new classes were added to the solution.
When I get time I will see if I can submit these modification to the source library, if they are required.
I want to add a help screen to my Codename One App.
As the text is longer as other strings, I would like put it in a separate file and add it to the app-package.
How do I do this? Where do I put the text file, and how can I easily read it in one go into a string?
(I already know how to put the string into a text area inside a form)
In the Codename One Designer go to the data section and add a file.
You can just add the text there and fetch it using myResFile.getData("name");.
You can also store the file within the src directory and get it using Display.getInstance().getResourceAsStream("/filename.txt");
I prefer to have the text file in the filesystem instead of the resource editor, because I can just edit the text with the IDE. The method getResourceAsStream is the first part of the solution. The second part is to load the text in one go. There was no support for this in J2ME, you needed to read, handle buffers etc. yourself. Fortunately there is a utility method in codename one. So my working method now looks like this:
final String HelpTextFile = "/helptext.txt";
...
InputStream in = Display.getInstance().getResourceAsStream(
Form.class, HelpTextFile);
if (in != null){
try {
text = com.codename1.io.Util.readToString(in);
in.close();
} catch (IOException ex) {
System.out.println(ex);
text = "Read Error";
}
}
The following code worked for me.
//Gets a file system storage instance
FileSystemStorage inst = FileSystemStorage.getInstance();
//Gets CN1 home`
final String homePath = inst.getAppHomePath();
final char sep = inst.getFileSystemSeparator();
// Getting input stream of the file
InputStream is = inst.openInputStream(homePath + sep + "MyText.txt");
// CN1 Util class, readInputStream() returns byte array
byte[] b = Util.readInputStream(is);
String myString = new String(b);
Using java, I would like some code that could get me the paths for:
1) Start Menu for Current User
2) Start Menu for All User
I need the answer for both WinXP and Win7. So hopefully there is a general answer that can get me both.
You have no other choice but to write a DLL and call native Windows API:
SHGetFolderPath(NULL, CSIDL_PROGRAMS, NULL, SHGFP_TYPE_CURRENT, &szPathBuffer)
SHGetFolderPath(NULL, CSIDL_COMMON_PROGRAMS, NULL, SHGFP_TYPE_CURRENT, &szPathBuffer)
If you really need the root of Start menu, use CSIDL_STARTMENU and CSIDL_COMMON_STARTMENU.
The full list of known folders: CSIDL.
If you target Windows Vista and above, use SHGetKnownFolderPath function instead of SHGetFolderPath.
You can use JNA library to call native Windows API without writing native code yourself but pure Java code.
Okay, I figured out a solution, but maybe someone else has a more eligant one.
I plan on doing something like "Runtime.getRuntime().exec(command);" and the command will be a "reg query" to query the following registry keys:
Current User can referenced by: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Start Menu
All users can be referenced by: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Common Start Menu
These are the same for both Win7 and WinXP. If anyone else knows of a better solution, I'll be happy to look at it too.
In my program I used a simple System.getProperty("user.home") + "/Start Menu/Programs" This gave me the user's Start Menu folder.
It worked on windows 7 and windows 10. I tried this because in order to get a user's desktop, all I had to do was call System.getProperty("user.home") + "/Desktop". SO I figured that it might work for the Start Menu as well, and seemed to have worked fine. I can delete and write files to the Start Menu just like I can with the desktop. Whether this is the right way to do something like this or not, I have no idea. But I'm just sharing what worked for me.
Another option is managing Start Menu items from vbs API.
I made a Java Wrapper for that.
// Install Start Menu
WindowsUtils.installStartMenuItem(WindowsUtils.SPECIALFOLDER_Programs,"my_start_menu", "explorer.exe", "http://www.google.es","Acceso directo a google");
// Uninstall Start Menu
WindowsUtils.uninstallStartMenuItem(WindowsUtils.SPECIALFOLDER_Programs, "my_start_menu");
i recently found this
public class VBSUtils {
public static String SF_ALLUSERSDESKTOP = "AllUsersDesktop";
public static String SF_ALLUSERSSTARTMENU = "AllUsersStartMenu";
public static String SF_ALLUSERSPROGRAMS = "AllUsersPrograms";
public static String SF_ALLUSERSSTARTUP = "AllUsersStartup";
public static String SF_DESKTOP = "Desktop";
public static String SF_FAVORITES = "Favorites";
public static String SF_MYDOCUMENT = "MyDocuments";
public static String SF_PROGRAMS = "Programs";
public static String SF_RECENT = "Recent";
public static String SF_SENDTO = "SendTo";
public static String SF_STARTMENU = "StartMenu";
private VBSUtils() { }
public static String getSpecialFolder(String folder) {
String result = "";
try {
File file = File.createTempFile("realhowto",".vbs");
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
String vbs = "Set WshShell = WScript.CreateObject(\"WScript.Shell\")\n"
+ "wscript.echo WshShell.SpecialFolders(\"" + folder + "\")\n"
+ "Set WSHShell = Nothing\n";
fw.write(vbs);
fw.close();
Process p = Runtime.getRuntime().exec("cscript //NoLogo " + file.getPath());
BufferedReader input =
new BufferedReader
(new InputStreamReader(p.getInputStream()));
result = input.readLine();
input.close();
}
catch(Exception e){
e.printStackTrace();
}
return result;
}
public static void main(String[] args){
System.out.println(VBSUtils.getSpecialFolder(VBSUtils.SF_ALLUSERSSTARTMENU));
System.out.println(VBSUtils.getSpecialFolder(VBSUtils.SF_ALLUSERSDESKTOP));
System.out.println(VBSUtils.getSpecialFolder(VBSUtils.SF_DESKTOP));
System.out.println(VBSUtils.getSpecialFolder(VBSUtils.SF_PROGRAMS));
//System.out.println(VBSUtils.getSpecialFolder(VBSUtils.SF_STARTUP));
}

I am trying to communicate with Excel from a Java/SWT application. I have been able to open a worksheet, open a file and save it but that's about it.
Can anyone point me to some documentation/examples for this? I especially need to know which commands are available. I did try to record macros to inspect. This was useful but did not give me everything I wanted.
This is a sample of what I have been trying so far:
private static OleAutomation openFile(
OleAutomation automation, String fileName) {
Variant workbooks = automation.getProperty(0x0000023c);// get User
// Defined
// Workbooks
Variant[] arguments = new Variant[1];
arguments[0] = new Variant(fileName);
System.out.println("workbooks::\t" + workbooks);
IDispatch p1 = workbooks.getDispatch();
int[] rgdispid = workbooks.getAutomation().getIDsOfNames(new String[] { "Open" });
int dispIdMember = rgdispid[0];
Variant workbook = workbooks.getAutomation().invoke(dispIdMember, arguments);
System.out.println("Opened the Work Book");
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
int id = workbook.getAutomation().getIDsOfNames(new String[] { "ActiveSheet" })[0];
System.out.println(id);
Variant sheet = workbook.getAutomation().getProperty(id);
OleAutomation sheetAutomation = sheet.getAutomation();
return (sheetAutomation);
}
Use VBA help MSOffice. Also you can use Object Browser in Office's VB editor.
Not a documentation, but since you asked about the available commands via automation: have you tried the OLE/COM Object viewer that comes with the Windows 2000 resource kit? Download here.
