How can we hide the cursor?

Can you change the Z-order of the controls, such that this edit control is not the first one given focus? Or, can you disable the control?

There is only one control on my dialog, yeah, i can disable it, but i need enabled Cedit control, what happens if i change z-order?

thanks

You need it enabled but read-only, is that right?

Nothing, when there is only one control.

The purpose is to show some text on it, that is all

Then why not just use a static control, or a disabled edit control?

Re: Hide cursor on CEdit?

Because the Cedit control supports a link, or colored text, that is why i am using it, or what else would u recomment?

You can have colored text just as easily with a standard static control.

Yeah, i just found an article about it, here is the link
I am gonna use CStatic instead of CEdit, but i am still wondering, why can not we hide caret?.....
anyway the topic is open to discuss!!!

Thanks David.

Convert a char[ ] to int[ ]

Hey all,

What is the easiest way to convert a char[] to an int[]so that the elements of the int array are the combination of 4 char elements?
Here is an example of what I mean;

if

  <code>
char tempChar[8] = {0};
int  tempInt[2]  = {0};

tempChar[0] = 0x00;
tempChar[1] = 0x11;
tempChar[2] = 0x22;
tempChar[3] = 0x33;
tempChar[4] = 0x44;
tempChar[5] = 0x55;
tempChar[6] = 0x66;
tempChar[7] = 0x77;</code>

how do I get

  <code>
tempInt[0] = 0x00112233;
tempInt[1] = 0x44556677;</code>

Thanks!

One possible way is to add the most significant char to the int and move the bits to the left with <<, then the next one and so on.

thank you for the reply...

I was trying to see which is the fastest way to do this if I say have 100 elements in the int[]?

You can also use an union:

#include <iostream>

using namespace std;

union Char2int
{
unsigned char tempChar[8];
unsigned int tempInt[2];
};

int _tmain(int argc, _TCHAR* argv[])
{

Char2int c2i;

c2i.tempChar[0] = 0x33;
c2i.tempChar[1] = 0x22;
c2i.tempChar[2] = 0x11;
c2i.tempChar[3] = 0x00;
c2i.tempChar[4] = 0x77;
c2i.tempChar[5] = 0x66;
c2i.tempChar[6] = 0x55;
c2i.tempChar[7] = 0x44;

for (int i = 0; i < 2; ++i)
wcout << std::hex << c2i.tempInt[i] << endl;

return 0;
}

As I interpret your initial post, you may not get what you want with the proposed union solution.

NYTSX wrote:

tempChar[1] = 0x11;
tempChar[2] = 0x22;
tempChar[3] = 0x33;
tempChar[4] = 0x44;
tempChar[5] = 0x55;
tempChar[6] = 0x66;
tempChar[7] = 0x77;

This would in all systems, regardless of byte ordering, generate the following memory contents:
00 11 22 33 44 55 66 77

If you convert the memory contents above to two adjacent 32-bit integers you will, on a little-endian system like most systems running windows, get 0x33221100 and 0x77665544.

My point is that the union solution will work on a big-endian system, but not on a little-endian system in terms of how I interpret your question.
To make a portable solution you would have to walk through the char array, one element at a time, and shift the integer value like Nelek suggested.

Remember that the code above is not portable, and you should comment your code that it is so!

But since this forum is for VC++ code, and nothing was even remotely mentioned about portability, does it matter?

A simple casting should do the trick:

int* tempInt = (int*)tempChar;

But be carefull with byte ordering ! As the bytes are stored in an inverted way in memory. It means that if you have those bytes in memory:

0x00 0x00 0x00 0x01

And you interprete those bytes as an integer (like you will do with the cast), the resulting integer value won't be one (but 0x01000000).
