Try to stack trace in debug mode and find out from where did it originate or from which function in your app did it start. It will help you and us.

It seems that you are trying to call some data exchange function while control is not yet created (e.g. you can't do that for a control in dialogs constructor, because control is not yet created). could it be that you are calling UpdateData(TRUE) in dialogs constructor? if so, try to move that code to WM_INITDIALOG handler (OnInitDialog). however, this is just a wild guess without your code.

I think you will need to save your image files as TIFF files first, then they will be easy to concatenate, and then convert to PDF. LibTiff does that. Search for LibTiff and download it. It has various tools to concatenate tiffs, convert to pdf etc.

You did not mention to convert what format files to PDF. If they are tiff files, then half the work is done. If they are another format, then you could use CxImage (search for it on this site) to convert them to tiff first, then use LibTiff on them.

this is this.

I don't think you can do that. You can only split MDI child windows not MDI parent window.

Hope I got your question right.

Why do you need an MDI for this.

Just a simple frame inherited from CFrameWnd.

Split it up and assign it different views in different panes.

You can have nested panes.

Take a look at IdFromRowCol function.

Custom drawn Tab controls

Ive seen lots of examples of completely rewritten tab controls, but has anyone done what should be a relatively simple override of CTabCtrl::DrawItem and called the XP theme functions? I just want an XP looking tab control where I can change the text color of certain tabs, but cant get the drawing to look right Frown | :(

VC++ /updation problem in mfc

HI,

There are two classes A and B as follows

class A
{

public:

update_host(CString hostname);

}

class B
{

public:

get_hostname();
}

The get_hostname() gets the hosts name and then calls update_host as folows

A aobject;
aobject.update_host(CString hostname);

now this is what i do in update_host(CString hostname)

update_host(CString hostname)
{

m_hostname=hostname;
UpdateData(FALSE) //to update the value in the edit box.

}

now,when i execute it,i get the error saying

Debug assertion failed.
file:wincore.cpp
line:3095.

Please help in this regards.

Thank you.

I am taking assumption that Class A is CDialog Drived Class, have you checked, that Dialog Box is Visible State at the time UpdateData() is called?

As if the dialog Box is not created before call of UpdateData, the dialog box application likly to crash.

AFAIK, No.

The presence of WinMain and WinProc is what differentiates a Win32 app from a Win32 console app. A Win32 console app has got the main()-func.

Start->Run search path

What directories are searched for executables when we run a program from Start->Run
dialog box?

It starts MS Word if I just give "winword" in the Run dialog, but my environment variable
PATH does not have the directory "C:\Program Files\Microsoft Office\OFFICE11" which
has winword.exe. Anyone knows how this works?

thanks!

Re: Start-&gt;Run search path

Owner drawn2-Jan-06 19:43

I think it searches HKEY_CLASSES_ROOT\Applications. This is the registry key for all applications currently installed in the system.

These are the applications that are listed in the open with dialog box.

So this could be it.

Detecting setup with hook

Castylx2-Jan-06 15:34

Castylx

2-Jan-06 15:34

Hey Everyone,

Can anyone give me some direction on the best way to detect if a program is starting a setup/installation process for a windows XP machine? I'm assuming that a hook is the best way to intercept the event, but what can I look for? Is there a specific message event or anything that I can look for, a function that always needs to get called when software is being installed?

Any help would be greatly appreciated.
