Disable windows popup

wrote an application that uses twain for scanning an images using
a scanner.
when the scanner is not connected I get the return value and want to
display my own popup but there is another popup from the scanner.

I tried to call :

ShowOwnedPopups(DefWnd(NULL)->m_hWnd,false);

("DefWnd(NULL)->m_hWnd" has my main window handle).

Still the popup is shown. I think that probobly the popup is generated by
the operating system (Windows).

Is anyone can help me on this?

Thanks,
Lior.

Class redefinition error

1)Actually, what i am doing is to integrate two separate Excel & access automation applications into one.
2)First, i finish Excel automation(used excel9.olb(library) & included excel9.h as header file).Upto now it works fine.
3)Now The problem begins. For access automation functionality i use msacc9.olb & include access9.h as header file.As soon as i compile, even before adding any functionality, it shows class redefinition errors for _Application etc.

Apparently, these are due to the object models of Excel & Access which have some same class names like _Application etc. which cause the clash.
There seems nothing wrong with the code but with the libraries of access & excel which have some same class names.

How should i resolve the clash?Please, Please, Please Help!! Cry | :((

in your headers, did you thought to well add such code :

<font color=blue>#if</font> !<font color=blue>defined</font> (__MY_HEADER_H_INCLUDED__)
<font color=blue>#define</font>       __MY_HEADER_H_INCLUDED__
 
<font color=green>// your header content here...</font>
 
<font color=blue>#endif</font>     <font color=green>//__MY_HEADER_H_INCLUDED__</font>

i thought it was clear enough... it must round all your definitions in the header it is on...
so, the #if and #define must be before what you declare in the header (others #include can be before that, as they may have their own exclusive statements already) ans the #endif put at the end of the file...

if you have several headers in that case, choose different #define macros for each header, to avoid any problems...

you could look into any compiler header to see how to do...

well, please forgive me for asking rather stupid questions. i am a newbie.Let me restate what i have done.

the libraries msacc9.olb,excel9.olb provided by ms-office for automation are added to the project.These libraries contain header files msacc9.h & excel9.h. i include these header files at the top of the .cpp file of my application like this.
#include"msacc9.h"
#include"excel9.h"
Now, please give me directions to resolve the clash(classes like _Application are in both libraries)

The directives that toxcct suggested you to add should enclose all the 'code' in all of your .h files. Are you using AppWizard to generate the files for new classes ? If yes, these directives are automatically inserted in your code.
So if this is the case, the problem is probably elsewhere. Then post the exat and COMPLETE error message.

yes, it seems that he does have 2 different headers defining each a _Application class...

yeah, toxcct you are right.
Following errors are generated:
error C2011: 'FormatConditions' : 'class' type redefinition
error C2011: 'Module' : 'class' type redefinition
error C2011: 'Modules' : 'class' type redefinition
error C2011: '_Application' : 'class' type redefinition

These classes exist in both the headers(but they have different definitions.e.g, _Application object is an open access db for access header file while _Application object for excel header file is an open excel).I have used appwizard to generate related files.These headers are provided by msoffice.

Any Ideas please......

In VC++ , property pages are of three types - small, medium, large.
I have no of properties to set for activex control for which the specified
size property page is not suffient. So how to increase the size of the property page while creating activex control.

What do you mean by this? As it's just a dialog box, a property page can be made any size you want. The size of the property sheet, however, is governed by the size of the largest property page.

Sir,
I am writing a activex control and it has lots of properties.
I can't put all these properties on same page so for that i want big
property page in which i can put all properties of the control in same
property page.

Ok, but I still fail to see the problem.

This makes no sense. First you say that you can't put all of the properties on the same page, then you say that you want to put all of the properties on the same page. Which is it?

I've never seen such a message. Does it come from within MFC?

yes it comes from MFC when we compile our application with property page's size greater than specified sizes
