In ED (see sig) I use GetEnvironmentVariable() and SetEnvironmentVariable() before calling CreateProcess() and leave lpEnvironment = NULL.

Hello,
I have a RichEdit SDI, right now people can drag and drop text into the control (and thats what I want).. but I don't want people to be able to drag and drop files nor do I want them to be able to drop images into the rich edit control. How can I stop files and Images from being dropped into the control?? Any Ideas?

Read Ole Drag and Drop articles in MSDN. You can receive notification with a type of droped source.

Thanks,

Look the MSDN help on CRichEditView::QueryAcceptData. Did it solve your problem?

Am I misinterpreting this? I have an MDI View that I do a DestroyWindow() on. I had thought that when I do this, the member of the view being destroyed (pmyView->someVariable) would be cleared (and destroyed) as well.......but MSDN says it doesnt destroy the object. SO after destroyWindow() I can still do:
pMyView->someVariable = 7; ???????s since the object stil exists....
It seems wrong but MSDN says the object doesnt get destroyed. SO then if I wanted the myView to 'reset' I would have to go set its members to zero etc, for a fresh start manually? 
Appreciate your help,

I think so. The DestroyWindow() call will destroy only the window that is attached to the view object. It does not destroy the view object itself.

So if I destroyWindowed my View, then later recreated a new window for that same view, the members of that view would retain the values they had before? And I dont have to reasign them?

You are correct. Not sure what you are trying to accomplish, but keep in mind that the framework usually handles view creation/destruction on your behalf.

I set an initially false flag to true in my view class onInitialUpdate, then I later destroy the view. After that at some point, it gets created again: using pTemplate->CreateNewFrame. So I was wondering if this newly created view was going to remember what its old flag value is, or if I need to set it to false explicitly (I want it to be false when the window gets recreated....)

DestroyWindow() destroys the raw window (i.e. the object referenced by a HWND) that belongs to a CWnd (or derived) object, and not the object itself.

I create my ACcess database in VC code. THe records get added in somr random unsorted fashion using AddNew(). After I am all done, I want to physically sort this database on one column so that if I look in the database, the records have actually rearranged themselves. WE can do this manually but I am wondering if we can do this in code. If I do a select *, order by, that returns a "virtual" recordset where the indices of the files in it do not match the indices of the files in the actual databse. Any suggestions?

If I make a static object of class A a (public) member of class B, how can I use the member functions of class A implicitly? Without having to do A.Function() all the time? Is this possible? The same for variables, I don't want to keep doing A.Var .
Obseve everything, remember more...
|
|
|
|

If I understand you correctly, you have a member variable of type A in class B.
You now add code to class B , and want this code to access member function of class A, right?
You then have to give the scope of the call (i.e. writing m_var.function()).
Maybe what you want is derivation? You then can call the base class implicity.
But beware: deriving B from a models a 'is a' relationship. i.e. your green coloured dialog is a CDialog. Look if that is true with your problem.
My opinions may have changed, but not the fact that I am right.

I have a normal CDocument / CView application (VC6 SP5) which generally works very well. But if it is running with Windows XP I got severall times this error message: "Can not save unamed file" when I try to save a file. I have never seen this error before. Then there is also a file "mfc2e.tmp" in the folder where the file should be saved.
The file "mfc2e.tmp" contains the contens of the desired file.
The filename "mfc2e.tmp" seems to be the result of an tmpnam(),
but I didnt find any hint in the MFC sources.

I sometimes see a MessageBox "There is an unknown error in an unnamed file" in my application. And no, I am not generating it myself...;P
I feel this is the second best error message right after the famous message box with nothing in it.
This error seems to be connected with my application opening a temp-file while being a restricted user or the TEMP variable pointing to nowhere.
I would like to hear from your experience with this mysterious errors.
My opinions may have changed, but not the fact that I am right.

Nothing mysterious is happening in MFC. You have all the sources of the library and even it isn't a peace of cake, but you always can find the reason of unexpected message box.

Does anyone can tell me how to active the screensaver programmatically on MS Windows platform?
|
|
|
|
|
You can use
<br />
SystemParametersInfo(SPI_SETSCREENSAVETIMEOUT,1,0,SPIF_SENDWININICHANGE);<br />
to change the screensaver timeout thus triggering it after one second. Setting the timout to zero does not seem to work, so you'll have a minimum delay of one second.
Don't forget to change the timeout back to a normal value when you're done

Anybody help me how to create emoticons window, just like MSN Messenger did.
Please help me in this regard
Thanks

You have to create one by yourself, since there's no thing like a standard control for it. So you'll have to create your own source for it to handle everything like drawing etc.

Hello,
I am developing a dialog based application. It has a RichEdit Control. I derived it from RichEdit20A. Now all the properties have been closed. I apply all the properties by modifying the .RC file.
Now I do want to wrap the data, when it exceeds the RichEdit20A width. I also unselects the AutoHScroll, so that the data wraps, but it won't work any more.
Please anybody helps me in this regard
Phantom.
