//I want to dynamically create a new combo box just to the right of an existing combo box. The problem is I do not seem to be able to set the size of the dynamically created combo box. Any suggestions???
CComboBox* pExistingCombo = (CComboBox*)GetDlgItem(IDC_COMBO1);
//The new control should have the same stlye as the existing control
DWORD dwStyle = ::GetWindowLong(pExistingCombo->m_hWnd, GWL_STYLE);
//Get the edit area and drop area of the old control so they can be the same
//size in the new control
CRect rEditArea, rDropDownArea;
pExistingCombo->GetWindowRect(rEditArea);
ScreenToClient(rEditArea);
pExistingCombo->ShowDropDown();
//get the size of the drop area
pExistingCombo->GetDroppedControlRect(rDropDownArea);
pExistingCombo->ShowDropDown(FALSE);
ScreenToClient(rDropDownArea);
//Move the new control over to the right a little
rEditArea.right += 150;
rEditArea.left += 150;
//Build the new combo control
m_pComboNew = new CComboBox;
m_pComboNew->Create(dwStyle, rEditArea, this, 1222);
m_pComboNew->AddString("one");
m_pComboNew->AddString("two");
m_pComboNew->AddString("three");
//Question??? - How do I set the drop down size of new combo to be same as existing combo?
m_pComboNew->ShowDropDown();
 Thanks

Before creation, add this line:
rEditArea.bottom += rDropDownArea.Height(); The non-dropped height of the combo box is always determined by the size of its assigned font; sizing it vertically determines the dropdown height.

Thankyou for you prompt reply,
I tried with sendMessage ,but did not work out
SendMessage (handle1,WM_MENUSELECT,MF_MOUSESELECT,0);
Where handle1 is the handle of the destination window
WM_MENUSELECT is wparam parameter and mouseelect the LPARAM PARAMeter

Can anyone help with this one? I am in one process. I use getforegroundwindow ato get the handle to the active Window. However, If it is a view, it does not give me the control that has the focus. This is what I want. I have tried to get GetFocus, etc but nothing seems to work.
Any ideas?
Thanks.

I have an app that I have a file name as a cmdline data. I use __argv[1] to access this. I will store this to use later. If the file exists, when I try to open it it is fine.
However, I am getting a strange thing when the file does not exist. In my program I don't use it or allow the user to build a file using this name with new parameters. However, my program automatically exits and the OS tells me that the file can not be found. I have looked at my code backwards and forwards. THis has to be the OS or MFC doing this. I have a feeling it is the CCommandLineInfo and ...ProcessShellCommand... In MSDN, it seems to say that the file will be taken as a file to be opened by the App. Is there a way around this? I do not use the OPen etc functions at all.
This has been bugging me for half a day now. Thanks for any help.

ummmm how about not doing the command line processing but just pulling the filename for use later in your app?
situations to avoid #37:
"good morning ... how many sugars do you take in your coffee ... and what was your name again?"
coming soon: situations to avoid #38: "...and the dog was there too?"

Do you happen to use an MFC class, like CStdioFile, to open the file? I believe CStdioFile (and others) can throw an exception if the file doesn't exist. That could cause your program to exit if you don't catch the exception.
Just a thought...

I have been trying to change icon of executable by using APIs like UpdateResource. But this doesnt work for me. I always corrupt the resource . Infact the old ones remain there and new gets in but in corrupt form. I am using WinXP Pro. Can somebody guide me about how to do it.

Why are you using an API to change the resource? Use the Resource editor. The icon with the lowest resource ID is your program's icon - what shows in Windows Explorer, for instance. Make sure to have a 16x16 image, and a 32x32 image. Include a 48x48 image if want your icon to show up nice and pretty on XP systems showing files as "tiles".

No I need to change icon at runtime. I have one exe which has to chaneg some information in another exe which includes changing main icon. So it has to be done by API. I tried other libraries but nothing works. Can u help me.

Of course, my initial reaction to this problem would be to re-think your design.  But I can't think of a way to do it at runtime...

Well thanks for your time. I have found a solution.
The icons are placed in Exe with numbers 1,2.....So first number represents 32x32 pixel icon and 2 represents 16x16 pixel icon. The problem in my approach was that I was tryin to change Icon Group and Icons. But when I changed only Icons and not icon group it worked because icon group is just a refrence to it. If you want I can mail you the code I used.The second problem was in reading ICON file. I was not reading correct information which was causing corrupt icons in exe.It works fine using UpdateResource API.

hi
you can change/add the icon of ur application easily
You can import new icons from anywhere and then add them as your resourse(that will automatically added when u import)and delete/change name of IDR_MAINFRAME and rename the new icon resourse as IDR_MAINFRAME ...an easy and tricky way...hahahaha
ok try it now....!

No I wanted to change Icon of an exe at runtime and not through IDE. But now I have found a solution. Read my comment below.

You're going to have to use the UpdateResource() API.

I have 2 edit boxes, A & B. B cannot have a value in it unless A does. B is disabled until A gets a value. When the user erases the value in A, I want to disable and erase the value in B. This all works fine in the debugger with the following code:
if (m_VidValue.IsEmpty())
{
m_Prefix = "";
GetDlgItem(IDC_VID_PREFIX_EDIT)->EnableWindow(FALSE);
UpdateData(FALSE);
}
When I run the code outside the debugger, the field gets disabled, but it does not clear. I can make it clear by forcing a RedrawWindow(). Is there a better way to do this without redrawing and getting the annoying flicker?
Thanks in advance,
Bob

You could try using SetWindowText("") to clear an edit box, for instance:
m_Prefix = "";
CWnd *pControl = GetDlgItem(IDC_VID_PREFIX_EDIT);
if(pControl)
{
pControl->SetWindowText("");
pControl->EnableWindow(FALSE);
}

SetWindowText does not work either, unless I do a RedrawWindow().
|
|
|
|
|
Hmm, that seems odd. Are you doing the SetWindowText before you disable the window?
You might be able to get away with a RedrawWindow only on the edit box, and not the whole dialog, which may help the flicker problem.

Yes, I am doing the SetWindowText before I disable the window. I've also tried doing a RedrawWindow on the edit box, but that doesn't work.

Did you try:
GetDlgItem(IDC_VID_PREFIX_EDIT)->Invalidate();
