I've got an application, that I'd like to convert to C++ as a learning exercise.
I've got 1 dialogbox template that I'd like to use 8 times at once on the screen.
1 want 1 main windows, and to (I guess) attach these 8 windows (with a thread to control each one) to the main window.
Where can I find an example of doing this Create Main and attach stuff.
Thanks

With or without MFC ?
If MFC, the main window should be SDI or a dialog ?
~RaGE();

I don't really mind. I'd prefer straight Win32code, but really it is for learning, so MFC would also be fine.
I just would like to see an example of how to do it.

in MFC Version
Create your main and template resources. Create a class for each of them, CMainDlg and CTemplateDlg.
In InitInstance(), launch your maindlg with a
CMainDlg dlg;
dlg.DoModal();
In the CMainDlg::OnInitDialog()
Create your dlgs like this :
CTemplateDlg dlg1;
dlg1.Create(...);
do this for each dlg to set their special features. If they are all identical, you can create a table of 8 CDTemplateDlg and loop on them to launch them one after another.
Would be the same if the main dialog was from a doc/view architecture (SDI may be better in this case). In the CMainFrame::PreCreateWindow function, launch the 8 dialogs as explained.
In Win32, it is a little bit more complicated to get this, but it is nearly the same, except you will have to catch the Winodws messages by yourself.

I'm really sorry.
I get what your saying, I just can't fill in the blanks.
Are there any full example projects that do this?

I want to load the icon resource form an application.
What I know by now is that I will use LoadIcon function
HICON LoadIcon(HINSTANCE hInstance, LPCTSTR lpIconName);
how to get hInstance from an application (for example for WORD 2000)?
Please help

Actually, you might be better off using ExtractIcon()
For an MFC application....
<br />
int nIconIndex = ICON_INDEX;<br />
CString strExeFilename = APPLICATION_FILENAME;<br />
<br />
HICON hIcon = ::ExtractIcon(AfxGetInstanceHandle(), strExeFilename, nIconIndex);
Edited to add : Check out ExtractIconEx() too - this allows you to obtain small and large icons.

I was about to give the same answer as you, but somwthing told me that the guy who has asked it was not programming using MFC. Then I looked for how to get the hInstance from another application that the own (which is needed with ::LoadIcon()), and ... I did not find how to do it. Do you know how to do this ? I mean, retrieveing the hInstance of another running instance (with or without MFC) ?

I have never extracted an icon from an application because I never had to do it but I do know that ExtractIcon works for API as well. I also remember that if I wanted to get get the module of an application using API I would call HMODULE GetModuleHandle( LPCTSTR pModuleName )
where pModuleName would be the name of a dll or exe. If you use null then you get the current module. This is what I remember doing two years ago, because after that I started working on Unix machines and I kind of forgot most of the API that I knew. I didn't know much anyways.

There could be a function that does this for you - have a browse through the shell functions and interfaces to see if anything pops out. However, you could use this method....
Say for example, you are representing an MS Word document, myfile.doc
If you look up ".doc" in the registry under HKEY_CLASSES_ROOT, you will find the default value is something like "Word.Document.8" - it is on my machine, this may well vary depending on the version of MS Word you have installed.
If you then find "Word.Document.8" under HKEY_CLASSES_ROOT, you will find it has a number of subkeys. Navigate through these subkeys to find the default value for the entry shell/Open/command. (in this case, the full registry path is HKEY_CLASSES_ROOT/Word.Document.8/shell/Open/command)
This contains the name of the executable, which you can then interrogate for the icon!
Hope this helps!

I have a ".txt" file with m-rows and n-columns of integer values. I want to load them as a m x n matrix. Each value is between tabs.
I would like an implementation of that.
Thank you very much!

Something like :
int table[m][n];
FILE *f=fopen("file.txt","rt");
if (f!=NULL)
{
for (int i=0;i<m;i++)
{
for (int j=0;j<n;j++)
{
sscanf(f,"%i[here is a tab]",&table[i][j]);
}
}
}
fclose(f);
This is pure C, since I do not know what our app is like. This does not work as is, but it should give you a way to implemente it.

Hello,
I need to convert icons to bitmaps. I have written something that works OK on 2000 and other systems but that fail on XP: the transparent color is replaced by black instead of being well transparent. Maybe it is related to getting a "too many color" icon were the 256 colors version is enough for what I am doing...
Does anyone has something to suggest?
Regards

Can you send me the code?
I worked on somthing that does this exact thing some time ago and i might be able to help you....

Does your stuff work? My code is just around 10 lines of code where I build a DC, select an empty bitmap into, draw the icon with DrawIconEx in DI_NORMAL mode and that's it. Do you do something similar?
|
|
|
|

If you haven't already, you need to look at GetIconInfo. This function fills in a structure
with two bitmap. One is the colour info, and one is the transparency map. The transparent
part *should* be black on the colur bitmap, but you can separate it using the 2nd bitmap
for reference.

Iain,
I saw this one and definitly wanted to take a look at it... Thanks for the infor.

Okay tested it but it appears that the bitmaps returned are wrong. Basically I get my icon from the system image list in where the icons are 32 bit with alpha. When I get them I get a 256 color version but the conversion is wrong: some parts of the mask that are gray become black where as in the icon the matching pixel gets black also. So I get black.
What I need now is to force the extraction in 256 colors. The problem is that I get a handle to an icon in the system image list and I do not know where this icon is located on disk so I can't really extract it from the .ico file.
Anyone?

I don't know special api-calls for this ...
but maybe you can use the Windows command "net send" ???
(translated from a german windows ...)
NET SEND {Name|*|/DOMAIN[:Name]|/USERS} Message<br />
Example:
NET SEND ThomasBoseKenn "Do you need further help ?"
