it doesn't get imported saying it contains more than 256 colors. and when i try to copy paste, and use the bitmap id its working fine. but when pasting it on the dialog using picture control, there is color loss. is there a way to load it dynamically. please give me the code for it.

thanks

Look at the messagebox carefully it says its imported *correctly* the ide just cannot display it in design mode.
Import a bitmap ignore the msgbox add a picture control on the dialog goto properties and specify the bitmap id.

Man that was quick... Big Grin | :-D

Attach a CProgressCtrl Variable with the progress control through classwizard then

//Initialize the progress control
m_ProgressCtrl.SetRange32(0,100);
m_ProgressCtrl.SetStep(1);

....
//later in the program
//move the progress control one step
m_ProgressCtrl.StepIt();

thats all there is to it i think

Then it comes to be that the soothing light at the end of your tunnel
Is just a freight train coming your way

I am not fully sure but i have done once like this moons ago
Go to Project settings ->Debug tabe -> Give the destination (where the service exe is really deployed )path of service exe .
Same to do with Link tab . Rebuild the project .
if the path of service exe is different from /debug , then copy .pdb file to the destination folder alongside the service exe . Now I hope debugging works

Well what do you mean by "hook a toolbar" what do you want them to be able to do?

Thanks for you interest in this matter.

Actually i have to include a tool bar to an existing messenger for eg MSN Messenger. then how can i do that. i know how to develop a tool bar in VC++.
But how can i include it to that messanger (No source code). which is already existing and running.

Ok you want to attach a toolbar to an existing window... this can be done but it will be a very messy code... it don't know if MSN Messenger exposes any functionality to attach a toolbar you have to check that out, if it doesn't then

Create a HOOK DLL to inject into the MSN messenger then when the DLL initializes create a Toolbar window with the parent window being the MSN window.

The original point and click interface was a Smith & Wesson.

hi friend,
i think your requirement is to add a menu in a remote application. Kind of code injection mechanism. you can achieve this in a simple way.
1. get handle for target window (use find window, with class name and title or you can any other method)
2. once you have a valid handle you can get the main menu handle of target window.
3.with a valid menu handle you can attach a new menu , submenu any where in the current menu.

Hope you can try this, I am not mentioning the API’s Smile | :)

.

Thanks

Hi guys,

I have two applications - 1. dialog based application 2. MFC gui dll.

I have to send windows message from first application to second application. The problem is MFC Gui dll application is the child application of another window and the gui dll window has no name ( as title bar is removed ).

For sending windows message, we need the window name, In my case, the gui dll window has no name and it is loaded as a child window on a third party application, in which i have no control.

So how to send message from application 1 to application 2.

Please help me guys. Its urgent.

Thanks in Advance

I suppose you will use the window name in FindWindow function, you can use FindWindow with NULL in name and your Window's Classname in the next parameter and it will return the window handle.
