You could adjust the order of the controls in the dialog
so a different control gets the initial focus.

And/or you can use SetFocus() or WM_NEXTDLGCTL/GotoDlgCtrl()
to move the focus to a different control.

I just saw a method HideCaret(), but it didnt work
this->GetDlgItem(IDC_EDIT1)->HideCaret(); is this right?

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

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?

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?

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

Nothing, when there is only one control.

yeah, that is read only

Re: Hide cursor on CEdit?

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

Re: Hide cursor on CEdit?

Gofur Halmurat1-Nov-07 4:30

Gofur Halmurat

1-Nov-07 4:30

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

Re: Hide cursor on CEdit?

David Crow1-Nov-07 4:32

David Crow

1-Nov-07 4:32

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

Re: Hide cursor on CEdit?

Gofur Halmurat1-Nov-07 4:39

Gofur Halmurat

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.

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;
}

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