Hello everyone,
this is a sounds-so-simple gray hair maker. Please help out:
A single line edit control on my dialog contains So far nothing complicated. Now:
On an event I would like to add some long text at the cursor position, give the edit box the focus, select the whole text of the edit control ***AND** I would like to see the beginning of my long selected text ...
CEdit *pEdit = (CEdit *)GetDlgItem(IDC_EDIT1);
pEdit->ReplaceSel("This is some long and rather useless test text");
pEdit->SetSel(0, -1);
pEdit->SetFocus();
The problem is that the SetSel scrolls the edit box to the end of the selection. Is there a way to scroll to the beginning without loosing the selection?
If you know the length of the selection, you may do both .SetSel(Start, End) or .SetSel(End, Start) but always the caret and the scroll will be at the end of the selection.
WM_HELP

SetSel has one more parameter which is a default one. Does that help you? Look up the docs.

Thanks, Nibu,
yes I do read docs before asking  The third parameter is called bNoScroll and according to the docs it should scroll or not the caret into view. But this is not the point, since I tried both versions. Both get the same result: the edit box is completely selected with the end portion of the text being shown.
My guess is that the problem lies in the line of code before the SetSel:
CEdit *pEdit = (CEdit *)GetDlgItem(IDC_EDIT1);
pEdit->ReplaceSel("This is some long and rather useless test text");
pEdit->SetSel(0, -1);
pEdit->SetFocus();
The ReplaceSel will put the caret to the end of the edit windows and scrolls the text to the end. Already I have played around with the edit box scrolling functions to no avail. As I said, its making you gray hairs!
Regards
Thomas

pEdit->ReplaceSel("This is some long and rather useless test text");
CString csText;
pEdit->GetWindowText(csText);
pEdit->SetWindowText(csText);
pEdit->SetFocus();
This should help although it doesn't look good. 
Unless another suitable option is found you can use this.

Nibu,
once again, thanks and great work. This will work as long as indeed I choose to select all of the edit box.
In my real application I'm doing some autocompletion so I want a first part of the edit text not selected while my recenty added text is selected.
Maybe its my fault that my given lines of code were too much siplified to express this contraint. If you have further ideas, I would be really happy.
Regards
Thomas

So no problem. You first do whatever replacement or other stuff that you wish to do.
Then do GetWindowText and SetWindowText. I know that's not a natural solution.
But here are some other functions that I would like to bring to your notice...
SetCaretPos --> CWnd
PosFromChar --> CEdit
I tried these two but the caret didn't move. But you can try. Maybe you can make it work.

I'm developing some code to use the OLE automation features of Outlook and at runtime I'm getting an exception of 'Member Not Found'. Oddly this is occurring when I call the method GetCount() on a _Items class object. Now Intellisense and the .h/.cpp files tell me that such an animal exists, but since it is happening at runtime, I'm thinking I've ventured down DLL hell somehow. The offending code is
_Folders olFolders = olNs.GetFolders();
long nFolderIndex = 1;
long nFolderCount = olFolders.GetCount();
for ( ; nFolderIndex < nFolderCount; nFolderIndex++ )
{
_Items olItems = olFolders.Item(COleVariant(nFolderIndex));
long nItemsIndex = 1;
long nItemsCount = olItems.GetCount();
for ( ; nItemsIndex < nItemsCount; nItemsIndex++ )
{
_MailItem olMessage = olItems.Item(COleVariant(nItemsIndex));
...
Anybody got some thoughts on what to investigate here. Thanks.
Oh and if anybody has some pointers to informative websites that have examples of Outlook Automation in C++, those would be much appreciated.

I've never used outlook automation, but wouldn't olFolders.Item(...) return a _Folder object? You might need to do something like:
_Folder olFolder = olFolders.Item(COleVariant(nFolderIndex));<br />
_Items olItems = olFolder.GetItems();<br />
Just a thought...

Thanks, Steve. You could be right about that. I'll give that a go.

I tested things out and interestingly, there is no class _Folder declared. However there is a declaration of a class MAPIFolder which I used in it's place and at the moment all my code is compiling and running fine. I'm still struggling in getting to process some _Message items, , but that's another exercise I guess. Thanks for the assistance, though.

Greetings:
I am writing an application with Visual Studio 2003. I am using an C++ MFC Single Document Interface. My work has come to a dead stop because Visual Studio is not allowing me to add an event handler to the CMainFrame class.
It started when I added a push button to the apps main CFormView window. I wanted CMainFrame to handle it. I get an error message from Visual Studio:
"Add/remove of the function is impossible, because the parent class code is read only."
I have also tried adding a Windows message handler to CMainFrame (like WM_SIZE). Same complaint.
The "MainFrm.h" and "MainFrm.cpp" files are NOT read only. I checked their properties under Windows Explorer. Also, if I load either of these files into my editor and make a small change to them, they are saved without complaint. In fact, absolutely NONE of the files associated with this project, including sub-directories, are read only! They are all writable. I have also checked and verified that none of my source or project files have been inadvertently loaded into some other editor application.
Could somebody tell me what is going on?
Thank you,
Mark

I guess you are referring to using the "Wizards"? Try deleting files like the "Class Wizard" file and other intermediate files. <projectname>.ncb, .clw if they exist.

or
Since they are all writable you could use the Text Wizard.

Hi Mike:
Yes, that worked. Thank you.
Suffice to say that this is a bug in Visual Studio?

Hello guys,
I want to pass specific command line parameters to my application, when user
right clicks on a file(of any type), then selects Open with line and
then selects my application.
Which registry entries do I have to add ?
Thanks.

Are you sure they are still in the registry?

Odd. I just created an SDI application, modified the registry entry so that additional command-line parameters were passed in, and ran the application. I ran it once by double-clicking the associated file, and again by right-clicking the associated file and selecting Open With. In both cases, the additional command-line parameters were used.

At this point right here, do the correct registry entries exist? If they do, I'm not sure what the problem is.

There is any program from Ms Visual Studio 6 or .. ?

"graphics" ? Please specify.
VS has a Icon and Bitmap editor. Not all that great but without knowing specifically what you are trying to accomplish.....

make my own button "picture" (make a button look as Circle or oval) make the whole window of application another shape than rectangle

This is a very broad topic. The first part would be to get the graphics themselves. You can download them or create them using the VC bitmap editor or use a third party editor depending on your preferences. It is beyond the scope of these forums to discuss graphics creation.
Your best bet will be to get the graphics in .bmp format. Then browse the button classes on this site there are a whole bunch that will display bitmap buttons and select one for your needs and follow the instructions there.
As for reshaping the window, for Win2K or higher you could use layered windows and a transparent color key or you could use SetWindowRgn to set the window to a specific shape.
