Question about working HKEY_CLASS_ROOT\*\shell\

I am building a program that all the command "C:\myapp.exe %1" to be ran when a user right click any file and choses "Run myapp.exe" and also does the same for folders. This all work great but one problem with my keys removed to the REG the all CPP files will open in to VC++ when DBClicked. With my key in the REG all the CPP files will open myapp.exe because the shell decided to place "Run myapp.exe" add the top of the menu and make it default. Since I want all the files to "Run myapp.exe" I do want them to have them be default or users will get mad. Now I know there is Tutorials on the shell and file assocation on MSDN where it talks about when ShellExecute() is ran the shell lookes for the...

1) Open Key
2) Default Key
3) The first key in REG (I think this is where I am.
4) (I cant rememeber what was here.)
1) and 2) might be switch around.

...order of verbs to file the verb to use to execute.

Well that all I can say for now...

Any help...

It's about the "change one thing in an other dialog" stuff! Smile | :)

Let us say I create a new app with AppWizard.
I put a button on that dialog (Dialog 1).
When I push that button a second dialog (Dialog 2) appears that has WS_POPUP style.
Then I put a button on that dialog too.
When I push that button I want to for eg. change the caption on the button that is on Dialog 1, HOW??
I tried this:

CDialogOneDlg dlg;
dlg.btn.SetWindowText("TEST"); // dlg = 'Dialog 1', btn = a CButton on Dialog 1

But the compiler says there is no window??hmmm...
The dialog is already created so why this error message??
Confused | :confused:

It's true that the C++ object of the dialog is created but not the window. The window will be created when you call something like dlg.DoModal();

As for the 2 dialog issue, you can save the pointers of the first dialog in the 2nd one and thus once the 2nd on is displayed, you have the access to all of the controls in the first one.

CDialogOneDlg dlg;
dlg.btn.SetWindowText("TEST");

there you create a new CDialogOneDlg. You must get a pointer to you'r previous CDialogOneDlg, (CDialogOneDlg* dlg) and for this you will have to do something like

CDialogOneDlg* p_dlg;
p_dlg = (CDialogOneDlg*)this->GetParent();
p_dlg->btn.SetWindowText("TEST");

I've always used V_BSTR or V_BSTRT macros.

COleVariant ov;
CString x;

ov = ...;

x = V_BSTRT( &ov );

Each icon ID consists of two icons- a 32x32 and a small 16x16. Theres a combo box in the icon editor to select between them. Chances are you've only changed the large one, but its actually the small one that is used in most situations. Edit those and rebuild.

Sorry to dissapoint you all with my lack of a witty or poignant signature.

Hi, I`m just starting to develop some TWAIN compatibility in my program for scanners etc. but I haven't got a clue where to start, can anyone give me some good links to the information I would need to successfully implement TWAIN? I would obviously prefer somewhere that offered it for free. Big Grin | :-D

Many Thanks,
Alan.

Thanks Chris, its just what i need. I have, since asking the question, also managed to find a TWAIN wrapper on this very site, for anyone wanting an alternative.

Many Thanks Chris,

I am having problems adding a dialog to a static library.

I have created a static library with MFC support, and then went to the menu and selected insert/resource which gave me a dialog to work with. However I want to assign a class to the dialog and do things with it, but The class Wizard option is unselectable. any ideas please??

Starting app and waiting for termination

5-Nov-01 2:34

Hi
What's the easiest way to start an application and wait until it has finished?
Should I use ShellExecute or CreateProcess?
And should I use a timer to check if the app has finished or is there a better way?

regards

Re: Starting app and waiting for termination

Tomasz Sowinski5-Nov-01 3:10

Tomasz Sowinski

Use WaitForSingleObject with a handle returned by CreateProcess. ShellExecute doesn't return the handle, but you can use ShellExecuteEx.

Your thread will be stopped until the spawned process runs.
