it has nothing to do with vc++....

look at what you wrote :

ShellExecute(NULL, "open", "winzip.exe", "-e -s"+bcs+" E:\\bcs.zip","C:\\extract\\here", SW_SHOWNORMAL);

You already gave a command line ("-e -s"+bcs+" E:\\bcs.zip") just add the proper password command line ....

Open a command line box and do it manually then use that for your ShellExecute values.
It might be worth copying the command line to a window so you know that you have generated the correct comand line.

Shouldn't -e be one of -ex, -en, -ef, -es, or -e0?

Is bcs the actual password, or is it a variable containing the password?

Although this settings doesn't crash my tested application....

Maybe you should concider this:

Owner draw
Controls the owner-draw characteristics of the list box. Possible values are as follows:

· No (default): Turns off the owner-draw style. The list box contains strings.
· Fixed: Specifies that the owner of the list box is responsible for drawing its contents and that the items in the list box are the same height.

CWnd::OnMeasureItem is called when the list box is created and CWnd::OnDrawItem is called when a visual aspect of the list box has changed.

· Variable: Specifies that the owner of the list box is responsible for drawing its contents and that the items in the list box are variable in height.

CWnd::OnMeasureItem is called for each item in the list when the list box is created and CWnd::OnDrawItem is called when a visual aspect of the list box has changed.

How to Load Icon

FarPointer23-Apr-06 0:54

23-Apr-06 0:54

Hi ,
Iam using the following code to load an icon

HICON hIconImage;<br />
hIconImage = (HICON)LoadImage(NULL, MAKEINTRESOURCE (IDR_ICON ), IMAGE_ICON, ICON_SIZE, ICON_SIZE, LR_LOADTRANSPARENT|LR_CREATEDIBSECTION );

But hIconImage is NULL after the loading.

Regards,
FarPointer

Your first parameter of the LoadImage is

(Taken from MSDN Smile | :)

"hinst
[in] Handle to an instance of the module that contains the image to be loaded. To load an OEM image, set this parameter to zero."

so why do you use NULL? use something like AfxGetInstanceHandle()....

Detecting that an executable is already running (so duplicates don't run)

Hey folks:

If you only want to have one instance of your .exe running, how can you detect that it is already running, and then exit gracefully?

(MFC is OK, but no .NET please), and I'm a noobster so please keep that in mind when answering :P

There are lots of ways of doing this. One is to use a mutex (see the CreateMutex API): You call CreateMutex with a unique name (a name which contains a GUID is the smartest choice) to create a mutex. Then if the call succeeds you call GetLastError and if it returns ERROR_ALREADY_EXISTS you're not the first one so you bail. There are ways you can do it using COM also.

I think any named kernel object will do, it does not have to be a mutex.

Yes, there is no need to use a mutex if you prefer some other option. As I said, there are many ways this can be done.

I do not know the answer, but please do no post every error message. Once they start to repeat them selves it becomes redundant and you are wasting sever storage space. You need to figure out why the first error says the type is a redefinition and go from there. If you solve that problem the rest of them will probably go away.

Redefinition usually means you have included a header file more than once.

There is an important nuance to note: I think Elaine's answer is correct for the first errors, where redefinition is the problem, but some other errors point out that the multiple definitions have different linkage. This would mean that the multiple inclusions could have some of the conditions change. For example, if this was in a header file:

#ifdef USE_C
extern C {
#endif

typedef struct {
int x;
int y;
int z;
} Vector;

#ifdef USE_C
}
#endif

Then if one inclusion defines USE_C and the other doesn't then you may get the diferent linkage error, because one will declare the structure as C and the other as C++.

Looks like it's becase your including both "winsock2.h" and "winsock2.h". It looks you're meant to pick one or the other - I'd choose "winsock2.h".
