In my case I found that the best solution was the creation of several XML files (one for each language needed) with all the text needed referenced by a unique id and call each text from within the code like: GetMessage(int id).
then, the only hardcoded part is the id of the message, not the whole string.

Hi,
Is there a free downloadable C++ Class design tool.
I am not looking a complex tool like UML tools. Simple tool which can represent the class and the properties in form of a diagram..
Thanks,

What about MS Visio? It's not free but it comes with Office packages and it meets your goals.

This message will not be sent, when i use SetItemText to change the item
text.
I want the parent to be notified when SetItemText is called, because I don't call SetItemText in CListCtrl's parent.

Look for LVN_ITEMCHANGED or LVN_ITEMCHANGING message

I tried, but it didn't work.
There is no LVN_ITEMCHANGED or LVN_ITEMCHANGING when SetItemText is called.

Hi,
the CListCtrl is in a dialog?
Have you create a dialog member function for this CListCtrl (e.g. OnItemchangedMyCListCtrl)? (This is OK at my projects)
Or have you the dialog member function "PreTranslateMessage" and look for the LVN_ITEMCHANGED message?
Greetings

Maybe I can not express myself.I mean that I want to develop a ActiveX control container.
Firstly, my document CxxDoc is derived from COleDocument,and the constructor as following:
CxxDoc::CxxDoc()
{
// EnableCompoundFile();
// ^^^^^^^^^^^^^^^^^^^^^^^^^^I need a flat (uncompound) file.
...
}
Is it OK????
Secondly,my client item is CxxClientItem
class CxxClientItem : public COleClientItem
The WriteItem and ReadItem function (copied from the sample program of ActiceX control test container in Visual C++) as follows. They can work correctly in compound document. Please tell me how to change them from compound document to flat(uncompound) document.

I am still using this 2024. Your example is useful and helped me through the jungle. i is an integer not a string. varindex.lval = i;
Than things are working, already. Maybe someone else can use.

Hi, I'm looking for a little help with some code I'm working with.
I'm still learning C++ and would like to use the PlaySound function to play a short (1sec) .wav file when iValue (detailed below) is an integer value of 15, and a different short .wav file if iValue = 14.
This is the code segment I'm currently working with:
if (iValue != -1) {
sprintf(acString,"%d",iValue);
} else {
sprintf(acString,"%s","None");
}
SetDlgItemText(IDC_VALUE,acString);
iValue shows an integer between 0 and 15 depending on input (and shows blank if there is no input).
I've been trying to get it to work for a while, any help would be greatly appreciated.

|
|
|
|
use switch
switch(iValue)
{
case 14:
PLaySound....
break;
case 15:
PlaySound....
break;
}

Hello,
Is there a way to get a file icon for a given file extension? I'm displaying a list of files that may or may not exist on the computer and I want to display the correct icon for each file.
I'm currently using a method that uses SHGetFileInfo, but this only works if the file exists on the machine.
Any suggestions?
Thanks,
Ian

|
|
|

According to the MSDN reference for SHGetFileInfo[^], you can use it to get information on the properties of a file extension "if the uFlags parameter includes the SHGFI_USEFILEATTRIBUTES flag".
The remaining problem is to get a list of file extensions of interest. Since you have a list of candidate filenames, you can use those directly. If you need to enumerate the extensions on the machine, the quick-and-dirty method would be to enumerate the keys under HKEY_CLASSES_ROOT in the registry.
Software Zen: delete this;

Could you not create a temporary file (with the right extension), call SHGetFileInfo, and then delete the file?

|

|

 Clever solution... I'll keep it in the back of my mind as a last resort...
Thanks.

Try ExtractIcon().
Otherwise, you'll need to call AssocQueryString() to get the executable associated with the file extension, load that executable using LoadLibrary(), and then call LoadImage() or LoadIcon() to get the icon's handle.
