How do you open another form when you click on a command button.
This sounds like VB syntax, or have the terms "form" and "command button" been moved into VC++ .Net also? What exactly is it that you are trying to do?

I am trying to open another dialog when you click on a button. For example when a user clicks on a button called eg Payment I want it to open the dialog called payment.
Thanks

hiho@ll
i'm using the Visual Studio .Net 2003 Setup Wizard Project
to create a Install Shield for my Application
during creation of the setup files i get an error and a warning:
Error: urlmon.dll must be excluded because the source file c:\windows\system32\urlmon.dll is under the windows system file protection.
Warning: iphlpapi.dll must be excluded because the source file c:\windows\system32\iphlpapi.dll is under the windows system file protection.
i'm running WinXP service pack 2 using the Administration account
for MFC71D.DLL it works, but it's also in the windows\system32 directory!
what's the difference between mfc71d.dll and urlmon.dll, iphlpapi.dll
(excuse for my bad english)
thx@ll

MFC71D.DLL is the Debug version of the MFC runtime. The redist.txt file supplied with VS.NET 2003, which lists the files you're allowed to redistribute, does not list this file. You should build a Release version of your project and include the vc_user_mfc71_rtl_x86_---.msm merge module in your package. If you have not yet built and tested a release version read Surviving the Release Version[^].
urlmon.dll is part of Internet Explorer and must not be redistributed. If you require a particular version of this component you should ask your users to install that version of IE.
iphlpapi.dll is part of Windows and must not be redistributed separately.
Redistributing components that are part of Windows is a major cause of "DLL Hell"[^]. This was precisely why Windows File Protection was added to Windows: to prevent this kind of erroneous redistribution of OS components.

Does anyone know how to create an icon in a program? I would like to create a icon that has dynamic text to be displayed in the systray or elsewhere. I've found examples of how to draw text on bitmaps, but I can't seem to find an example of how to do this with an icon.
Thanks in advance for the help.

Lookup CreateIconIndirect in MSDN.
You have to draw your text onto two bitmaps, The first on is the colour bitmap that has the icon as you want to see it, and the second is a black and white mask bitmap that is used for the outline of the opaque and transparent parts of the icon, black being opaque and white being transparent. Use CreateIconIndirect to combine these two bitmaps into an icon.
[plug]
Check out http://www.codeproject.com/tools/imageviewer.asp[^] for a tool that makes it very easy to debug bitmaps and icons.

Wow! Now why couldn't I find this on my own? Must have been having a blond moment.
Also, thanks for the explanation and the plug. This should give me enough to keep me at the keyboard and away from the family for a while 
Thanks!

Anybody know how to make small size enums (less than an integer)?
|
|
|
|
|
An int is 4 bytes, whereas char and short are 2 bytes. Does that help?

Yes...But how to make enums small like it?
|
|
|
|

Good question, that may not be so easy to answer.
- Some compilers make the size of enumerated types variable, and enough to store the values they store (signed/unsigned 8,16,32 bits).
- Some compilers allow to set the size of enum types via compiler flags (I did not see any correspondign flag VC that does this)
- C and C++ have a different interpretation of enum values.
- VC uses a fixed value of 4 bytes for storing enum types.(As David said before)
IMHO, don't use enum types if you want to 'store' values that their size is important.(Even if these values are 'constants')
Just wanted to help.

I'd like to read the text in a couple of richedit controls. This should be done by hooks.
I have installed a syswide hook written in a DLL, with source taken from a project here.
There seems to be alot of helpfull "angels" here, and I'd like som help to understand what's wrong with my app.
The Winspector Spy program receives the EM_REPLACESEL wich contains the newly added line to the control. They can also display the text, so winspector spy can hook messages syswide, and display the text I'm looking for.
But how do I implement it? I havn't seen any projects here that can do what I'm asking for. But I think that some of you know more about winspector, and maybe know how to be able to read the EM_REPLACESEL messages.

The hook is installed like this:
g_hHook = SetWindowsHookEx(WH_GETMESSAGE, (HOOKPROC)msghook, g_hInstance, 0);
The msghook function is located in a DLL (as the other hook handling functions).
With this code, should my program receive all messages in the system?
The msghook function it looks like this:
...
...
if( msg->hwnd == g_hSpyWnd ){
PostMessage( g_hServerWnd, g_uSrvMsg , EM_REPLACESEL, msg->lParam );
}
...
...
The problem is that my program only receives messages if I the window I spy on has focus....any ideas why?
|
|
|
|
|
Correct line:
PostMessage( g_hServerWnd, g_uSrvMsg , msg->message, msg->lParam );
And the only message my hook registers is WM_PAINT. Why is that? Do I have to install the hook in another way to get messages posted in the richedits messagequeue?

The easiest way is to save the data to a .csv file. A simple text file where every row is a line of text and every column is seperated by commas. Excel can read .csv files to import the data.
If you want to get more difficult, you can search this site for "excel" and you will get articles on reading and writing excel files using ODBC, ADO, COM, etc.

From Microsoft Excel Help
[quote]
The format of information pasted from the Clipboard
How pasted information appears in a document Information you cut or copy to another program is pasted, if possible, in a format that the program can edit. For example, cells from Microsoft Excel worksheets and records from Microsoft Access are pasted into Word as Word tables, complete with column widths and font formatting. Text separated by tab characters from Word is pasted into Microsoft Excel in rows and columns of cells, and records from Microsoft Access are pasted into a Microsoft Excel worksheet as rows with each field in a separate column.
If a program can't edit the information, it inserts it as an embedded object, which you can edit in the source program by double-clicking the object. If the information can't be inserted as an embedded object — for example, you're copying the information from a program that does not support OLE, the information is pasted as a static picture that cannot be edited.
How to format pasted information To control the format of information pasted from the Clipboard, use the Paste Special command (Edit menu) instead of Paste

hi !
i'm looking for an article which explain how to extract an audio file from an avi file
someone can help me ? plz
thx

You need to download the directX9.0 SDK. It has documentation in their for all such things. Specifically look up Directshow, there is an example program called "playwnd" or you may be able to download it seperately. It has code in there for play back video streams, and audio.
But you will need to read the directshow info from the help to understand how to use it. Once you do though its dead easy to create complex multimedia apps.
