HideCaret is a bad idea unless you're the one that called ShowCaret.

I have only one control on my dialog, if so, what should i do?

thanks

In your dialog class OnOnitDialog() override, try

SetFocus();
...
return FALSE; //<-- just doing this may work

You can also disable the control, but it will look different.
You can also use a static text control, but it too will look different (although
you can maybe use WM_CTLCOLORSTATIC to provide a specific background).

That's all I can think of at the moment Smile | :)

No problem.

Did you get a solution? If so, what worked?

BTW, I still think it's silly that read-only edit controls show the caret Smile | :)

How else would you copy text from them?

Well there it is then.. I no longer think it's silly!

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?

Gofur Halmurat1-Nov-07 3:53

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?

Gofur Halmurat wrote:

Nothing, when there is only one control.

Gofur Halmurat1-Nov-07 4:12

1-Nov-07 4:12

yeah, that is read only

David Crow1-Nov-07 4:14

1-Nov-07 4:14

So what is the purpose of this read-only control?

Gofur Halmurat1-Nov-07 4:30

1-Nov-07 4:30

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

David Crow1-Nov-07 4:32

1-Nov-07 4:32

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

Gofur Halmurat1-Nov-07 4:39

1-Nov-07 4:39

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.

Convert a char[ ] to int[ ]

1-Nov-07 4:49

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.

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.

Help me to understand what I'm saying, and I'll explain it better to you

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;
}

Thanks George and everyone else for their help....this is exactly what I was looking for in order to save processing time.

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

NYTSX wrote:

tempChar[2] = 0x22;
tempChar[3] = 0x33;

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.
