So what object are you calling DoModal() from?

CDialog dlgAbout(IDD_ABOUTBOX);
dlgAbout.DoModal();
|
|

Just an idea to research further. Before you instantiate the dialog, would it not be possible to modify the IDD_ABOUTBOX dialog resource to change the caption property? I don't know how to do that, but that is one thing I would investigate.

I *think* this is what InitModalIndirect() was suggested for. Like you, however, I've not personally tried it.

Other than looks, what reservations do you have to this approach? Read here for Paul's response to using a CDialog object directly.

I had a quick scan through the answers below and you didn't seem that enamoured of any of them as you weren't using/couldn't use MFC.
Having said that you've already answered your own question...
mikert_2008 wrote: One way I know to change the title of Modal Dialog Box is to use OnInitDialog() function of the class derived from the DialgBox and then call setwindowtext() function inside it.
If you look at the MFC documentation or read the source code you'll see that CDialog::OnInitDialog is called in response to a WM_INITDIALOG message being sent to the dialog box. All you have to do in your code is handle WM_INITDIALOG and call SetWindowText at that point.

Hi,
I am asking your help instaed I am using 3rd party library as I know I will not get help from them..
I have third party tools which is having almost 7 (dll and .dll.a) files and 10 source .h and .c files.
I need to add only source and .dll.a files and keep along with this file.
But I am getting run time error "Unhandled exception at 0x00018740 in Sample.exe: 0xC0000005: Access violation reading location 0x00018740"
I think I application is not able to read code from dll file. Or else what might be the cause?

This doesn't make any sense.

Use your debugger to locate the problem more precisely and inspect the different variables. Once you have more information and are still stuck, post the details here.
Basically, the error message means that you are trying to read at a memory location to which you are not allowed to (it could be by trying to access a NULL pointer, or an unitialized pointer for instance, but it could be from a lot of other reasons). The only way to fix it, is to inspect your code with a debugger to find the problem.

How can I make sure that I am able to use all dll files?

Hello,
I have an application that allows you to import contacts from outlook,
when you click on import it open that outlook 'folder select menu' and you select the folder you want to import the contacts from.
so far it's all good,
what I want to do now is to make this automatic,
I need to find a way to save the selected folder, so next time the user will load the application it will know from which folder to take the contacts from.
This is the code I'm using now:
_ApplicationPtr pApp;
_ItemsPtr pItems;
MAPIFolderPtr pFolder;
HRESULT hr;
hr=pApp.CreateInstance(__uuidof(Application));
pFolder = pApp->GetNamespace(_bstr_t("MAPI"))->PickFolder(); //here the user select folder
pItems=pFolder->GetItems();
.....and so on
basically I need to save the selected MAPIFolderPtr pFolder to the registry as a string
and then convert it back to MAPIFolderPtr pFolder from the string.
Thank you!

OK after breaking my head with that for over a day I found a solution:
1. pFolder = pApp->GetNamespace(_bstr_t("MAPI"))->PickFolder();
2. char *folder_id = _com_util::ConvertBSTRToString(pFolder->EntryID);
3. _bstr_t new_folder_id = _com_util::ConvertStringToBSTR(folder_id);
4. pFolder = pApp->GetNamespace(_bstr_t("MAPI"))->GetFolderFromID(new_folder_id);
save folder id:
1. select folder
2. save the folder id to char
... write to registry or whatever
read folder id:
.... read from registry or whatever
3. convert it to bstr
4. get your selected folder by its id.
hope this will help some one.

I have application on Visual C++ 6. I made dump file when it was working and open the dump in Visual Studio 2005. In the dump I cannot see what happened inside mfc42u.dll, because file mfc42u.pdb I have 'does not match'. I retrieved that mfc42u.pdb from msdl.microsoft.com/download/symbols. Where can I get file mfc42u.pdb that will be 'match'?

For Resolving the diamond ring problem we derived the base class as a virtual. Then what are the size of following class:
Class Base
{
public:
virtual void Play();
}
Class Derived : public virtual Base
{
public:
virtual void Play();
}
Class Derived1 : public virtual Base
{
public:
virtual void Play();
}
Class Derived2 : public Derived,Derived2
{
public:
void Play();
}
Now question is Sizeof(Base) = ?? and why??
Sizeof(Derived1) = ?? and why??
Sizeof(Derived2) = ?? and why??
Sizeof(Derived3) = ?? and why??
What are the object layouts??

I have to load a .png image on my button. Can some one please help me out how I can do this in MFC.
Thanks in advance..
|
|
|
|

You can load PNG images using CImage[^] class.
Another option is a GDI+ Bitmap[^] class.
And if you are using MFC 9.0.30411 or later, you could also use a CPngImage[^] class.

Thanks for ur reply, can u please provide me some code example..
Thaks a lot

You mean load the image on a button click event or load the image and display it on a button (image button)?
|
|
|
|
|
I mean load the image on the button drawitem().
|
|
|
|
|
In that case I'd suggest you read this[^] article about buttons that support PNG files with transparency.
You could use the class provided in the article directly or
you could investigate the source code to see how it works.

How to find the average, worst complexity of a code??
say for ex,
for i= 1 to n

}
for j= 1 to i
{
x=x+1
}
Please help me ..

Huh? 
Did you bother looking at your post? Notice anything "strange" about it?

You have to claculate from your program; for this example
first for loop execute "n" times and second loo execute n times because value of "i" is "n"
suppose "T1" time need to execute one iteration in the first for loop and "T2" time needs for one iteration in second loop
so it take T1*n + T2*n that is an order of n, ie it depend on input variable "n"
This is the time complexity
