Hi bruspark
I think
if your buttons are gray you need to functions for button and check Id from Buttons
|
|
|
|
|
When you created the toolbar and filled in the members of the TBBUTTON struct, you can set the initial state of the button. You should use TBSTATE_ENABLED to enable them and 0 to gray them. You can then use the TB_ENABLEBUTTON message to programatically enable/disable the buttons.
To show and hide buttons you can use the TB_HIDEBUTTON message.

 The problem is :when i create a button in toolbar,i got the ID of the button,but how can i make the buttons recieve the click event ?
with the classwizard we can map the command to the buttonID,when i click the buttons,handler fuction is called...
however,now ,the buttons is created dynamicly,and we don't know the buttonID in advance.The classwizard can't work in this case.
i can call the PostMessage() fucntion to inform the buttons created dynamicly. the problem is how can the buttons recieved the click event and
where do i place the message handler fuctions?

Maybe the whole toolbar is disabled : MyToolbar->EnableWindow(TRUE);

Hi all,
Can anybody help me to reposition the default tooltip that is shown by a treectrl when the item text is clipped inside the ctrl?
I simply want to avoid the clipping of this tooltip when the ctrl is near to right edge of the screen. In this case the default tooltip is clipped by the screen. So I want to move it to left to avoid this clipping.
For example, the treectrl of the workspace in VC-6 IDE is doing the same. If we placed the worksapce toolwindow to right, the tooltip will not go outside of the screen.
Thank you.

This depends on the mouse position. Tooltips always appear relative to your mouse position.

You will have to sublcass CToolTipCtrl and handle TTM_POPUP. Check mouse co-ordinates to display tooltips accordingly.

Hi
Have what I think is a pretty easy question for most of you,
but I dont know how to solve it unfortunately... so here goes.
Have programmed a Progressbar in a dialogue and want to keep
track of the progress. Works perfect, but sometimes the entire
window stops updating during the calculation and only updates
when everything is 100% done. The same effect can be simulated
when some other window gets focus, then my main window does
not update anymore until the function is done.
Have tried things like:
CWnd *Main=AfxGetMainWnd();
Main->RedrawWindow();
in my function to update the window, but it does not work.
Any one of you have a simple solution?
Regards
Abris

Use a Timer.
For more info take a look at WM_TIMER.

Use Thread to update the Progress bar,
|
|
|
|

You can write the thread that will update ur progressbar window as well in the mean time you can handle other stuff.

Hmmm, seems like threads is the solution then?
Tried the Timer thing, but it did not work at all.
Added the following code to the OnTimerEvent in my main dlg.
this->Invalidate();
this->UpdateWindow();
this->RedrawWindow();
m_TheFileDownLoadProgress.RedrawWindow();
m_TheDownLoadProgress.RedrawWindow();
When inside the Filedownload function and the dlg looses
focus this code does not help however, it still does not update
the Progress bar. Only thing that it gave me was an very annoying
blinking window from all the updates 
Threads I have so far never tried, seems like a complicated
solution? I'll take a look, but I would have guessed there was
some simpler way to do it....

Hi all,
I'd like to add a "print in progress dialog" in my applicaiton when some printing is going on. How can I do this?
Thanks in advance,
Sarvan AL

There is no direct way to determin if something is in the process of printing or if it has finished. Once you have created your document and passed it on to the print spooler your app has finished with it.
One thing you could do is hook the spooler window, and display your messages that way.

Hi all,
In my MDI application, I've used ResizeParentToFit() function for all of my formview children. If the MDI parent window is maximized, everything works fine. If it is in default size, the child windows are getting the scrollbars. I'd like to have the child windows without scrollbars.
If anybody could show me some path, I'd be very thankful.
Thanks in advance,
Sarvan AL

Hi,
I place some line , rectangle, ellipse graphic elements in the view.
As the application goes background and them come in the front..
all those things are lost. So how to bring those back when the view
gets painted in this case.
Do I have to use CMetaFileDC and play the meta file back in paint.
But in this case the file gets created in the current directory. I dont
want this.
Thanks

Hi Tran Ngoc Minh
you can use GetOpenFileName
|
|
|
|
|
::OPENFILENAME ofn;
char *szFileName=new char[1024];
ZeroMemory(szFileName, sizeof(szFileName));
ZeroMemory(&ofn, sizeof(ofn));
ofn.lStructSize = sizeof(ofn); // SEE NOTE BELOW
ofn.lpstrFilter = "*.bmp;*.*";
ofn.lpstrFile =szFileName;
ofn.nMaxFile = 1024;
ofn.Flags = OFN_EXPLORER | FN_FILEMUSTEXIST|OFN_ALLOWMULTISELECT|OFN_READONLY;
ofn.lpstrDefExt = "bmp";
CString str;
if(GetOpenFileName(&ofn))
{
CString str=ofn.lpstrFileTitle ;//szFileName ;
CString temp;
str.TrimLeft();
int index;
while(str.GetLength()>0)
{
index=str.Find('\0') ;
temp=str.Left(index);
str=str.Mid(index+1,str.GetLength()-1);
}
}
From the above you can get the name of the selected file

To show the Browse dialog use CFileDialog class.
