You can get a handle to a messagebox window and then you can change text of it.

MessageBox is a modal window so it blocks the calling thread. So once you call MessageBox then unless you dismiss it nothing else can be done.

I saw my files it was on the C#.

I hate to do this but it is not going to work in C# as well. System.Windows.Forms.MessageBox mimics MessageBox in windows. So there is no option to use just the Cancel button.

Why c# is good I think its easy to learn anyway maybe you like to see Dissecting the MessageBox[^].

I never asked why C# is good!!! We were talking about MessageBox. I have seen that article and it create a new class for doing custom stuff. It has got nothing to do with MessageBox WinAPI provides.

I don't think it is possible with MessabeBox. You can simple create your own dialog and add a single cancel button.

How to change resource FORMVIEW's language(In VC.net IDE)

2-Jul-08 18:59

You are welcome. Btw you may want to check out XMessageBox - A reverse-engineered MessageBox()
[^]. It has more functionality then standard MessageBox and also allows custom buttons.

I want to format 3 digit numbers as follows
if number is 6 then add "00" before number; SNumber = 006
if number is 15 then add "0" before number; SNumber = 015

CString givenTEXT;
GetDlgItemText(IDC_ID, givenTEXT);

int TEXTvalue = givenTEXT;
CString tempTEXT;
if (TEXTvalue < 10)
{
tempTEXT="00" + TEXTvalue;
}
else if(TEXTvalue < 100)
{
tempTEXT="0" + TEXTvalue;
}
else
{
tempTEXT = TEXTvalue; //error: "=" operator is ambiguous
}

if i change the last line to
tempTEXT = "" + TEXTvalue;
it compiles but tempTEXT is all screw up : "..\include\Atlexcept.h"

Help with _tioa and other conversion routines

Try this.

int i = 15;
CString str;
str.Format("%03d", i);

I've tried the conversion routines and still get errors. I receive from an edit box a number. I want to add something to that number and then put it into a CString. can someone show me a code example that works Please. I can get the number find but I can't add something to it and then put it back into a CString.

I am sorry, what exactly is the problem? Perhaps some code you tried will help.

For instance : int a = 42; CString str; int tmp;(pEdit already established) pEdit1->GetDlgItemText(str); now str holds the value the User typed which was NOT a number. but the representation of a number in character format. Now tmp = _tstoi(str); WORKS it changes the character to a number and puts it in tmp(an integer). but my question is How do I do the reverse? How to I get an integer valve into the CString(ie str)?

I've tried these functions: _itot_s, _itoa_s, and _itoa and they all give a long error message basically saying the str cannot be transfered to a char*

I know there is something that works, but I can't recall what it is.

I just want to put an integer value into a CString after I have converted one from the User's entry.

Okay I think the problem is _itot excepts second argument to be either wchar_t* or char* depending whether unicode is defined or not and it cannot automatically convert from CString to char* or wchar_t*. I don't use much MFC so not sure if there are function in CString to automatically do this but you can try something like this:

int i = 42;

CString str("50");
int temp = _ttoi(str);
	
temp += i;
TCHAR buffer[50];
_itot(temp, buffer, 10);
str = buffer;

works until the last statement: str = buffer; at this point buffer does indead have the value I want, but I get an Access violation error when the assignment operator in CString tries to assign buffer's value to the CString(ie str).

check CString format function

CString tmp;
int a = 5;
tmp.Format("%d Hey ", a);

Hope this helps.

I get this error: "Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast"

That should be:

CString tmp;
int a = 5;
tmp.Format(_T("%d Hey "), a);

Here's a tip:
Choose a string character type and stick with it.
The three common choices are
char (ANSI)
wchar_t (Unicode)
TCHAR (Generic - either char or wchar_t based on build configuration)

MFC uses generic types and, except for OLD APIs, so does Windows, so if you're using MFC,
generic is probably the best choice - unless you want to have to conver strings every
time you call a Windows or MFC API.

CString is also a generic type - it's either a CStringA (ANSI/char) or
CStringW (Unicode/wchar_t) depending on the build configuration.

If you choose to use the generic types, use them everywhere.
That means:
Use the Generic Text Mappings[^]
Wrap your string literals with the _T() macro
Use CSring instead of CStringA or CStringW

IMO, this stuff should be second-nature. You shouldn't have to think about it.
It's VERY worthwhile to take the time to understand it completely.
