I have an app that is controled using keypresses. Currently I use WinProc to capture the key presses and process them. My problem is non US layout keyboards. Example: If I wanted to test for a '?' key press on a US layout keyboard, I get a 'Shift' keypress and a '/' keypress. Most other international layouts do not have the '/' and '?' on the same key so this does not work. Is there anyway to capture a '?' or any other non-alphanumeric keys that require either shirt or alt to be presses. I.e returning the unicode of the key. Can this be done using windows API or should I be looking elsewhere? SDL or something?

Hi, I have an dialog based app that has an initialisation dialog and a main dialog (property sheet). I have to switch between these dialogs and keep the non active one hidden. My problem is how do I put a minimize button on a Property Sheet dialog? Thanks ---

It simply does not exist with my install of MSVC or any of the other work computers with MSVC. I have a lot of other activeX controls that I can include, just not MSChart. Did I miss it on the install? ---

Hi all, I need to add a chart control to my dialog. I can find references to MSChart on the web but as far as I can tell I do not have that object on my system. Is MSChart something that is included with VB installation? The only charting objects I can find are Microsoft Office Chart 9 and 11. I need to add data to the chart from user input one point at a time. What can I do? ---

Appart from not knowing how to get infomation from an unknown exception, I have fixed my code problem. COLORREF Clr = GetDC()->GetPixel(Rect.left-1, Rect.top-1); This line does not like being called so often.(why??) So I just set Clr to the background color as it actually does not change after initilising it. Clr = RGB(m_bkR, m_bkG, m_bkB); cheers ---

First thing I tried, it seems it does not throw a CException at all. I am sure it is a memory resource overflow problem, even though I am deleting my HBRUSH object. ---

Hello I was trying to debug this code (see below), because after a few minutes it crashes. So I used a try{ }catch(...) to catch the exception but I dont know what type of exception it was. Is there a way to tell? I tried using TRY{} CATCH_ALL() but it dod not catch anything?? try{   DeleteObject(hbr); //must be deleted or eventually mem overflow    hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);    if (nCtlColor == CTLCOLOR_STATIC )    {      CWnd *Ctrl = GetDlgItem(pWnd->GetDlgCtrlID());      if (Ctrl)      {        CRect Rect;        Ctrl->GetWindowRect(&Rect);        this->ScreenToClient(&Rect);        COLORREF Clr = GetDC()->GetPixel(Rect.left-1, Rect.top-1);        hbr = CreateSolidBrush(Clr);        ASSERT(pDC);        if(!m_staticTextBgd)                 pDC->SetBkColor(Clr);        pDC->SetTextColor(RGB(m_fntR,m_fntG,m_fntB));        pDC->SetBkMode(m_staticTextBgd?OPAQUE:TRANSPARENT);      }   } } catch(...) { printf("Error"); } I tried catching CResourceException and CMemoryException and many others but it did not catch anything? How do I know what exception is being thrown? ---

Hi, I have SDI app that load files through CWinApp::OnFileOpen. When the file dialog opens it is in the last opened directory. Normally this is the wrong directory.:( When My program starts and File open is selected I want it to open in my default directory. How can I set this without overriding OnFileOpen and using a CFileDialog :confused: Thanks ---

Thanks, that was rather stupid of me :) ---

How can you tell if a CWnd object is displayed or not. I can never figure this one out. If you initilise the object but not displayed as a window what function can I call to test it? ---

Thankyou, that was easy and quick. (quick *slap* to the forehead) (and yes I do actually have a return type) ---

Sorry about a non MFC question, but I thought we should have some good C++ Programmers here. I have a base class and a inherited class. class base { base() Initialise(); }; class derived : public base { derived(); Initialise(); } base *root; Within my view class I want to initialise root as either the base or derived class. I do this with the following code. switch(version) { case 0 : root = new base; break; case 1 : root = new derived; break; } root->Initialise(); This howerver always calls base::Initialise instead of the derived even for case 1. What can I do to call derived::Initialise :confused:? Of course I could create a pointer to derived and typecast chamber_root, but I dont want to do that. Also I could derive another class from base and use that instead of base. ---

I have a SDI and I dont override the standard file open ( i.e CWinApp::OnFileOpen() ), I do however use a separate CFileDialog to open a particular type of file. When I use the CFileDialog to open my files I set the initial directory to open from (different from the executable dir). Then when I use File->Open it uses the CWinApp::OnFileOpen and the initial directory is the last directory from my CFileDialog, I expect this. However I used SetCurrentDirectory to reset this directory but it still uses the previous value. It also uses this value when I retart the program and choose file->open. How can I set this to always open in the executable directory for file->open. I dont want to override the OnFileOpen and use a CFileDialog. ---

This colors in the excess space in the CStatic where there is no text, I.E making the unused space blend in with the background, I want the space behind the actual text to be colored, this is done by not using pDC->SetBkColor(Clr); in the method OnCtlColor. But I dont know how to change this from light gray. ---

I am writing a program that displays static text on a black background. I can change the CStatic object backgound color to black or I can set the space behind the text to the standard light grey color I.E the space directly behind the text not the entire CStatic area (toggle m_staticTextBgd see below). I want to change this light grey to another color. I tried SetSysColors but I dont want to change this at a system level. Thanks if (nCtlColor == CTLCOLOR_STATIC ) { CWnd *Ctrl = GetDlgItem(pWnd->GetDlgCtrlID()); if (Ctrl) { CRect Rect; Ctrl->GetWindowRect(&Rect); this->ScreenToClient(&Rect); COLORREF Clr = this->GetDC()->GetPixel(Rect.left-1, Rect.top-1); DeleteObject(hbr); hbr = CreateSolidBrush(Clr); if(!m_staticTextBgd) pDC->SetBkColor(Clr); pDC->SetTextColor(RGB(m_fntR,m_fntG,m_fntB)); pDC->SetBkMode(m_staticTextBgd?OPAQUE:TRANSPARENT); } } return hbr; ---

I have a simple program used for a video overlay where I use a CStatic object to display the time. I was looking at the memory usage for the program and discovered that it was increasing by 4k every 3-4 seconds:(. I found that the following code was the culprit, to be more specific, the SetWindowText line. (The code is called every second) CTime t1 = CTime::GetCurrentTime(); std::string time_str = (LPCTSTR)t1.Format("%H:%M:%S %d/%m/%y"); m_timeStatic.SetWindowText(time_str.c_str()); //memory increase I swapped over to use a CString object instead but the same problem was encountered. m_timeString = time_str.c_str(); UpdateData(FALSE); Please Help me!!!! Can anyone explain this!!!:confused::confused: ---

It crashes at TRY { CModelessMain::Create(...) } CATCH_ALL { ... } END_CATCH_ALL Never tried CoCreateInstance - will give it a go ---

Hi all, I have a problem. I have written a program that uses a commercial activeX component. I need to distribute this program on other machines and in order to do that I need to also distribute the commercial .ocx file and register it. This is no problem. What I want to do is for my program to send a popup error message if the ocx file is not installed/registered with windows. Currently it just crashes. X| thanks ---
