Hello,
I am creating an application that is stylistically similar to outlook express. I'd like to be able to create header or banner images, with anti-aliased text that can be changed dynamically. They would be displayed in the MainFrame, and would describe the nature of the current view (in outlook express, these are Inbox, Outbox, Sent Items, etc).
At the moment I'm simply using CBitmaps that load bitmap resources.
I guess the way to do this would be to create a class that inherits from CStatic or CBitmap, and uses GDI to draw the anti-aliased text. I'm at a bit of a loss as to how to proceed though - should I use an existing Codeproject class, or roll my own? My requirements really are simple - I want anti-aliased white text across a plain background, as a drop in replacement for my existing CBitmaps, that looks like outlook express.
Regards,
Sternocera

Hi All,
Please let me know whether we can call functions of a win32 dll from a vb.net application.

Yes, we usually can.

Yes you can, follow these two steps.
Step 1: You have to declare this DllImport attribute which allow specifying the name of the dll which contains the method.
Step 2: Then you have to specify the signature of the API, after which you can call the method passing the correct parameters.
As for example:
[DllImport("User32.dll")]
static extern bool MessageBox(IntPtr hWnd, string lpText,
string lpCaption, uint uType);
IntPtr hWnd= this.Handle;
MessageBox(hWnd, "Hi", "Click Me", 0);
hWnd is the handle of the form.

hi,
i need to have the right cursor position , does not matter which font size is being used,
for example if the ::GetCaretPos(lpCursorPos) gave me lpCursorPos-> y = 4
when the font size was 10 it must also give me 4 if the font size is changed to 72,
please help.
Thanks.

Have you tried GetSel()?

Hi Guys,
I can't seem to find any articles on how the OS Mutex's behave if they are not closed. I'm looking to use a mutex handle to check whether there are instances of various applications open prior to running an installer, but one of the apps is a C++ app, and in the event of a catastrophic failure, it may end a process without releasing the underlying Mutex.
What effect would this have on the system? Would the Mutex state be invariant, or does ending the holding process free the mutex as well?
Regards
Tris

Please use the documentation of CreateMutex[^] as a reference.
The mutex will be automatically released when the process terminates.
Here is a snippet from the documentation -
The system closes the handle automatically when the process terminates. The mutex object is destroyed when its last handle has been closed.
The documentation makes some recommendations to check for application instances.
Here is a snippet that explains this -
If you are using a named mutex to limit your application to a single instance, a malicious user can create this mutex before you do and prevent your application from starting. To prevent this situation, create a randomly named mutex and store the name so that it can only be obtained by an authorized user. Alternatively, you can use a file for this purpose. To limit your application to one instance per user, create a locked file in the user's profile directory.

Cheers, i wasn't entirely clear on whether the Mutex would self release after a Process exits from a catastrophic failure.

If nobody owns up for a mutex (orphaned), the OS immediately closes it. Also, locked file idea suggested in the docs may not be very helpful if you want your application to be truly one-instance (across logins). But, in such a case, only a kernel object (like Mutex) can help you.

hi, i created a custom MFC dialog box, and I need to call it in a function in a dll file, but when i call it it keeps saying IDD_BOX undeclared identifier, even though i've included the dialog box's header file. how do i call a dialog box in a dll file?
|
|
|

Are you sure that IDD_BOX is really defined?
You need to google first, if you have "It's urgent please" mentioned in your question.
