You can NOT mix 32 and 64-bit code in the same process. You either have to recompile your app as 32-bit or install the 64-bit Oracle client.

Indeed.
I had to install the 64-bit Oracle client.
Now I'm trying to config the application to use 64-bit or 32-bit Oracle client according to the processor type using the configuration in the app.config:
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Oracle.DataAccess"
publicKeyToken="89b483f429c47342"
culture="neutral"
processorArchitecture="x86" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="Oracle.DataAccess"
publicKeyToken="89b483f429c47342"
culture="neutral"
processorArchitecture="Amd64" />
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
Thanks for your help Dave.

Hi,
I writing a small application which will notify whenever any windows messages or Dialogue boxes appear with any of the (Error,Information,Warning,Question) Icons.
this is how i am doing..
main()
{
WinHAn = FindWindowA(NULL,"Windows Security");
if(WinHAn != NULL)
{
EnumChildWindows(WinHAn,SearchIcon,(LPARAM) &winIconSearch);
}
}
static BOOL CALLBACK SearchIcon(HWND hwnd, LPARAM lParam)
{
style = GetWindowLongPtr(hwnd, GWL_STYLE);
if ((style & SS_ICON) == SS_ICON)
{
thisHan =(UINT64)SendMessageW(hwnd, STM_GETIMAGE,IMAGE_ICON, 0L);
searchHan =(UINT64) LoadIconA(NULL, (LPCSTR)(IDI_WARNING));
if(thisHan ==searchHan )
{
printf("Icon Found");
}
return TRUE;
}
This is only for Warning messages.But it is not working. can any body tell me what the problem is..
Thanks.
vvk.

You might add some more output to your program to see which code is reached or use the debugger for the same purpose. E.g. if a window with the title "Windows Security" is found and if such a window contains a static control with an icon.
Your check for SS_ICON is wrong (but this is not the reason for finding nothing). You should use:
if ((style & SS_TYPEMASK) == SS_ICON)
Finally I'm not sure if this can be done this way. While the LoadIcon description states that it may return a handle to an existing resource, this may be only true when the icon has been loaded by the same application.

Stepping through your code with the debugger will identify where it is failing. Have you checked that there is a currently open Window with the title "Windows Security", to satisfy the FindWindowA call? By the way, it is really bad practice to use the A or W suffixes on your Windows API calls. Use the project settings to set your project to ASCII or Unicode mode, and let the compiler generate the appropriate code.

Hi,
i have tried with debugging and the it is failing at the if condition if(thisHan ==searchHan).Sendmessage function('thisHan') is returnig one value and where Loadicon function is returning('searchHan') different value.
|
|
|
|

So the icons don't match. All that tells you is that the icon for the message window is not the one you were hoping for. The chances of you being able to use this code in a production environment are not very high, since very few applications will be doing things the way you expect or want.

Hi,
My application menu items which are created dynamically. When window DPI settings gets changed and set to 'Larger (150%)', menu item text is not visible as it is very big and hiding behind the toolbar.
How can we set menu item font size or complete menu pane itself using VC++ by code so that it will be visible in all the DPI settings?
Regards,
Aniket

Have you looked at the GetMenuBarInfo function? You can get the RECT of the menu-bar with this function.
I.e
MENUBARINFO mbi;
mbi.cbSize = sizeof(mbi);
GetMenuBarInfo(hwnd, OBJID_MENU, 0, &mbi);
printf("menuBar rect (screen) = %d,%d,%d,%d\n", mbi.rcBar.left, mbi.rcBar.top, mbi.rcBar.right, mbi.rcBar.bottom);
MapWindowPoints(HWND_DESKTOP, hwnd, (LPPOINT)&mbi.rcBar, 2);
printf("menuBar rect (client) = %d,%d,%d,%d\n", mbi.rcBar.left, mbi.rcBar.top, mbi.rcBar.right, mbi.rcBar.bottom);
Notes:
1. All of the members are 0 during the WM_CREATE message handler
2. The dimensions returned are in screen-coords.
Example output:
menuBar rect (screen) = 108,130,636,149
menuBar rect (client) = 0,-20,528,-1
When I tried to change the DPI setting with the program running, I was told I'd have to logoff and then login again. Am I correct in assuming that you change the DPI and _then_ open the program?
Also, is this a standard menubar, or is it an instance of a toolbar that's been added to a rebar control? The difference being that a standard one should be a part of the non-client area, and therefore the toolbar you have should be automatically moved down to accomodate the menubar having larger text.
If however, you have a toolbar inside a rebar control as your menu, the rebar container is a part of your client area, and you need to manually position the toolbar below it. Different DPI settings will change the required height that you need to offset the toolbar by.
Can you upload a screen shot somewhere and post a link to it?

Hi,
i have developed an application in which i have icons in left side pane of application which can be dragged and dropped in client screen. Application is working fine with all the resolution except 1920x1080.
when setting the resolution to 1920x1080 while dragging icons to client area, icon is not attach to mouse pointer. instead there is a gap between the mouse pointer and the icon. i wrote code to identify the screen resolution but it does not seem to recognize 1920x1080 resolution. below code is giving incorrect resolution for 1920x1080 setting.
RECT actualDesktop;
GetClientRect(GetDesktopWindow(),&actualDesktop);
value of 'actualDesktop' variable is {top=0 bottom=783 left=0 right=1536} which is incorrect. according to current resolution size value should be {top=0 bottom=1080 left=0 right=1920}. Due to this, all the icons while dragging are adjusting according to incorrect resolution setting.
Can someone help me to identify the issue and let me know if there is any limitation with respect to screen resolution in VC++ 6.0 with windows 8 environment.
If require i will place more detailed code about the drag and drop functionality.
Regards,
Aniket

That may well be your problem; VC 6 is very old and probably has many issues with Windows 8. I strongly suggest you upgrade to the latest version of Visual Studio.

Hi,
Thanks for replying.
But i am getting same issue when compiling in VS2012 in windows 8. code does not seem to recognize 1920x1080 resolution setting and downgrading my application look and feel by setting it to lower resolution.
Any help would be appreciated.
Regards,
Aniket

I would suggest that using GetClientRect is not the best way to get screen size as this may well take into account reserved areas on the desktop. You could try GetWindowRect instead, or better still use GetSystemMetrics with the SM_CXSCREEN and SM_CYSCREEN parameters, to get the physical dimensions.

Thanks Richard,
I was finally able to make my application DPI aware in VC6.0. Now i am able to get the correct resolution settings of my machine.
However another issue started after making these changes. Since the application is now recognizing the screen resolution and adjusting all child window according to that but the menu bar text seem not to be adjust at all automatically.
The text size of menu item is large and hiding behind the toolbar. How can i programmatically change menu bar text size?
Kindly suggest any solution.

Aniket

Please tell us the solution so other people may benefit.

Without seeing some code it's impossible to guess why.

Hi Richard,
I have added below lines of code in my App class init function to make the application aware of DPI settings.
HMODULE hUser32 = LoadLibrary(_T("user32.dll"));
typedef BOOL (*SetProcessDPIAwareFunc)();
SetProcessDPIAwareFunc setDPIAware = (SetProcessDPIAwareFunc)GetProcAddress(hUser32, "SetProcessDPIAware");
if (setDPIAware)
setDPIAware();
FreeLibrary(hUser32);
User32.dll library is present in "System" folder of windows directory.
After adding the above code, my application is now scaling according to DPI settings but menu items font size is increased too much so that it is hiding behind the toolbar.
Menu bar is created by default as it is created in a MDI application.
if(!m_wndMenuBar.Create(this))
{
TRACE0("Failed to create menubar\n");
return -1;
}
When application get scaled automatically based on DPI settings (Larger 150%), menu bar text become large and hide behind the toolbar.
Any help would be appreciated.
Regards,
Aniket

Why are you using LoadLibrary to get access to user32.dll when it is automatically linked in to just about every Win32 program ever written? Just make the direct call to SetProcessDPIAware, or better still do what is suggested at http://msdn.microsoft.com/en-gb/library/windows/desktop/ms633543(v=vs.85).aspx[^].
As to your menu issue I have no idea I'm afraid, the code you have shown above merely shows how a menu is created. It would also help if you used indentation and put <pre> tags around your code so it is easier to read, like:
if(!m_wndMenuBar.Create(this))
{
TRACE0("Failed to create menubar\n");
return -1;
}
Use the code button above the edit box.

Hi Richard,
I need to load User32.dll because in VC6.0 this library is not linked automatically and to make my application DPI aware, i have to load it manually.
As far as menu bar is concern, i found one strange thing. If i set my DPI settings to 'Large' (150%) or higher and open my application then at first menu is hiding behind the toolbar as the text of item big. But once I change my system text size (COntrol panel -> display -> change on the text size options) to any size and windows is refreshed and then my application menu become proper.
My doubt is that application is scaling child window and main window but not the menu item when opened first but when system text size is changed and windows is refreshed then application is also scaling all the text size according to system settings.
How can i make my application set all the text including menu according to system text settings in the first place.
Regards,
Aniket

Sorry, I don't know the answer. I can only suggest you try some further searching, or maybe one of the Microsoft forums.

Hi, I have a passport scanner to scan the passport image to the MFC client application. I was wondering if there is any method to enable the passport image populated on the MFC application could be able to transfer to another c# application an display on a popup window ?I am planning to form up a communication between the c++ and c# application, so that the passport image could be able to process in the c# web application once it was scanned from the MFC application connecting to the passport scanner. Thanks.

It's just bytes... use one of the many IPC types[^].
Sockets are likely your most commonly used IPC nowadays for a number of reasons, but there's always other options that have different benefits (and drawbacks of course). For example, simply having a shared file would be very simple since you just have to write the file to a shared location and then have a way of notifying the other application of the new file to process (notice can be done via Windows message or other such messaging mechanism, or simply have one application launch the other and load the proper file via command line arguments).
You have a lot of options, you have to decide what's important then implement accordingly. Happy coding!

I need to create one edit view which could be able to add different color txt automatially(actually by another thread). act like a monitor to monitor the message from serialport or tcp;
The message displayed shall be able have different color to make it has different meanings;(if different font is support is better)
Also when user scrolls up, it could stay at that scroll position, it did not scroll down automatically when new message arrived. User could select and copy the txt;
When user scroll down to the last line, it could scroll down automatically to the last line when background message is arrived; when scrolling, it did not flash(twinkle);
I have tried EditView & Richedit, all failed, the new txt added is by ReplaceSel, which will make the content auto scroll down to the last line, and user could not do Selection and copy when new txt added;
I have found the Visual Studio Trace window, it could add message automatially and user could easily select txt even when new txt added.
I am not sure how to realize it, this thing has bothered me a lot time, please someone could help me about this. Very appricate of your help;

You could try subclassing the EditView so you can have greater control over the movement of text and the actual display. Alternatively you may need to create your own View class which will be specific to your requirements.
