Re: changing an application's shell icon

AFAIR, the shell just grabs first icon it founds in resources embedded in .exe.

Thanks for your reply -- that makes sense about what icon the shell grabs.

However, is there any way to change which icon is displayed through the shell (like after the first time the app is run)?

Shell grabs *and* displays first icon in .exe. What do you mean by 'like after the first time the app is run'? App only registers its file types, not the .exe icon itself.

Insert this before #including Windows headers

#define WINVER 0x0500

No. In your program #define WINVER before including windows headers.

#define WINVER 0x0500
#include <windows.h>

Use 'Find in Files' command to search for COMBOBOXINFO identifier in your include directory. If it's not there, you'll need to download recent Platform SDK from msdn.microsoft.com.

Set the cursor at tagCOMBOBOXINFO, then press Ctrl+J. You'll probably see this line:

#ifndef NOWINABLE

Then press Ctrl+J again. On my workstation it goes to the following line:

#if(WINVER >= 0x0500)

What's displayed on your screen?

Post the #define WINVER and #includes. You've screwed something - maybe WINVER is #defined too late.

Move #define WINVER 0x0500 into stdafx.h. It must be placed before #includes.

I'm not sure I understand the question. Here's one way to store and print your array:

void printArray(char *array);

int main(void) {
char array[] = {'-','-','A',...,'Z'};//enter all letters of the alphabet

printArray(array);

return 0;
}

void printArray(char *array){
//code to print it in whatever format you need
}

im trying to create an Vigenere cipher demo.
It basically needs the alpabetbet grid to encrypt data.
There for the grid must be stored in a way in which it is possible to read up/down the column and row to get the chipertext.
i could do with any help on the code
thankyou

You can do a Vigniere cipher much easier than that. You don't need an array.

a character in C is simply an 8 bit number. eg, the letter 'A' is value 65. 'B' is 66 etc.

You can use single characters and numbers interchangeably.

eg. char MyNumber = 'A'; // MyNumber contains 65.

To this end, you can encipher characters just by adding or subtracting an offset to them.

Try this:

char message[]="This is the plaintext";
int shift=5;

cout << "Plaintext: " << message << "\n";

for (int i=0; i < strlen(plaintext); i++)
{
  *message[i] += shift;
}


cout << "Ciphertext: " << message << "\n";

That should give you a good start.

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

Visual C++ class view

Gutner19-Mar-02 1:52

The file names in my Visual C++ project have
extensions of "cc" and "hh" ( not the standard cpp and h ).
Class view does not work when these extensions are used.
How can I keep these extensions and make class view work properly?

I did not add anything to class view.
I created the project from .cc and .hh files.
As far as I know, the class view should work automatically.

COuld you at least think twice before posting? You can't add anything to ClassView - it's generated automatically.

The problem is not limited to ClassView. VC will not recognize your files as C/C++ ones even in 'Settings' dialog - they won't be compiled by C++ compiler.

Check the KB article Q181506 for solution.

Actually, this is a problem that I have already solved.
By changing the registry and some project options, you can make VC
compile files with the "cc" extension.
I can supply the details if you are interested.
