Hi,

I have an ActiveX control and its dependend DLLs within a CAB file that we use within our web application. I also use this same control in a fat VC client. We currently deploy the control for our fat client by an install shield script. I'd like to get away from having to deploy this control, since I know it's sitting on a local web server in a cab file.

Is there an API set that allows me to reference the CAB file rather than bundling the control in my setup script? In other words, I'd like my fat client to instantiate the object via an http call to my web server and pull down the control rather than me having to wrap it in my install script. Any ideas appreciated.

DeleteFile(pFileName)

Ever try actually reading the documentation?

My problem is more complicating than just one line:
DeleteFile(pFileName). In order to delete a file, you need to let the user search for a file first. I also need to create a progress dialog page.

Have you tried messing with CFileDialog to get the user selected file. Something like this could do (not tested)...

CFileDialog File(TRUE, NULL, NULL);

if (File.DoModal == IDOK)
{
     // yes, the user does wish to delete the file
     DeleteFile(File.GetPathName);
}
</code>

That should give the basic idea!

You don't need a progress dialog to delete a file. It's a one-step operation that takes but a second.

Im writing a C++ program, and I need to add a member variable to a class. This member variable is an object that takes 2 parameters to it's contructor. How do I declare the variable in the header of my class, and initialize it in the constructor of the class that I am using it in?

ROY! Please don't go!

Problem with VS editor.

Jack Handy14-Apr-03 10:01

14-Apr-03 10:01

When you hit the enter key in VS6 it inserts "\r\n" which drops you down a line. This is normal behavior in windows, however I'm editing C++ files that are being used in unix and the \r is an annoyance there.

My question is, does anyone know how to stop VS from inserting the \r -or- Is there a way to run a small script that would strip this out when you save the file?

Go to "File|Advanced Save Options..." For Line Endings select "Unix (LF)"

Unfortunately, this applies only to the active file (note the singular).

Is this in VC++ 6.0 ? Because I don't see "Advanced Save Options" under the File menu.

Thanks,

Sorry, I was thinking VC7.

I don't believe there is a solution in VC6 except to write a little program. (In fact VC6 will take files that have just LF and convert them automatically to CR/LF. By default, VC7 will preserve the original style.)

Re: Problem with VS editor.

Jack Handy14-Apr-03 12:11

Jack Handy

14-Apr-03 12:11

Mine seems to be preserving the original style. It only inserts the \r when I add a line.

Do you happen to know if it is possible to write a little script/program and have it be ran on the file when you hit save? Like a filter or something.

There is an event to tell you a document has been saved, but I don't think there is the ability to do what you want.

One solution would be to write an add-in and call it directly.

Re: Problem with VS editor.

Jack Handy14-Apr-03 13:12

14-Apr-03 13:12

Ok, Thanks for your help. Would you happen to know how to access this event? I wouldn't mind writing a program that cleans up the file right after each save.

Check out the add-in documentation. You probably could also do this as a macro, but I don't remember how (the last Visual Studio macro I wrote was three years ago.)

If you are working with Unix and Windows at the same time, I recommend you installing Cygwin[^].
One of their utilities is u2d and d2u (Unix to Dos/Dos to Unix), which make the conversion you need.
I know that installing Cygwin just for this is overkill, but I think you should give it a try, since it can really ease when you are working with multiplatform code.

overriding functions

ns14-Apr-03 8:45

14-Apr-03 8:45

A little confusion.

We can override OnOk(), or PreTranslateMessage(), but not SetWIndowText() right? What makes a function overridable? Is it that only event handlers are overridable? I'm reading about the word "virtual" but dont see it in the members of say CWnd...like GetWindowTExt etc. I looked in "Input Message Hanfdlers" which has functions like OnHScroll, OnKeyDOwn etdc which are ones that I've seen overridden yet they dont say "virtual" in the declaration (in MSDN)

short answer: you can override any function, in a derived class. but whether your overridden function is called or not depends on who's calling it, what kind of object the caller think he has and the "virtual" option...

i tried to explain it... but realized that this does a better job:
