If your using CreateWindow(Ex) you have to set the hight to the hight you want your dropdown window to go because a ComboBox has it's integral hight so setting the hight just afects the dropdown not the ComboBox.
ex:
hComboBox=CreateWindow("ComboBox",NULL,dwStyle,0,0,400,200,hWnd,(HMENU)iIdCB,hInst,0);
else
if it is on a dialogbox just drag the middel point as far as you want the dropdown to go
i hope this helped

I created the box in the resource editor on a Dialog form.

If it's a size problem, either increase the size of the drop-down portion in the resource editor, or see here.

Hi all,
when some one enters a hex value in a edit box ,say for example 0xffff
,then is there any way by which the value can be retreived as integer itself (not as text)??
when i retreive the data as text and try to convert it using atoi or atof routines the output is always 0.It'd be great if someone through some light on this ......
Thanks in advance

You can use strtol[^] to convert your hexa string into a long. With this function, you can supply the base (which is 16 in your case).

strtol[] did the job...Thanks for ur help

Hello everyone,
Thank you for your suggestions in my previous message.It's working.As next step, i want to send my uint8 values here to serial port.For that i added two lines into my code (bold) but i receive this error,
[Linker Error] Unresolved external '_outportb' referenced from H:\INTERFACE\INTERFACE.OBJ
(Interface is the name of my file in which i saved my code and files)
I didnt get the cause of problem,what's wrong?. If anyone has an idea, would be pleased!
#include<stdio.h>
#include<conio.h>
#include<dos.h>
#include<stdlib.h> // system()
int transmit (double x);
int i;
system();
outportb(int port, unsigned int);
int transmit (double x)
{ union ifas
{
double d;
unsigned char u8value[8];
};
union ifas member;
member.d = x;
printf("\nmember.d=%d\n",member.d);
for ( i=0 ; i<8 ; i++)
{
printf("\nmember.u8value[%d]=%f\n",i,member.u8value[i]);
outportb(port,member.u8value[i]);
}
return 0;
}
int main(int argc, char* argv[]) //Console
{
double var;
scanf("%lf",&var);
transmit(var);
system("pause");
return 0;
}
Regards,
Cahit

%d format specifier is signed decimal integer. For your double, use %f. For your unsigned ints, use %u

Well, actually, since you have chars in your union you should use %c instead of %u.

Use unsigned char for u8value

Hello,
I am not able to find any function which will get me the line no. on which the cursor is present in RichEdit Control in MFC? How to get it? Is there any function to get it? If yes, then what is it?
Thanks,

Hmm - never needed that.
But does GetSel() followed by LineFromChar() work?
-- modified at 7:58 Thursday 17th August, 2006
Just found it in the Doku for LineFromChar():
"If [the Parameter] nIndex is –1, it specifies the current line, that is, the line that contains the caret."
"We trained hard, but it seemed that every time we were beginning to form up into teams we would be reorganised. I was to learn later in life that we tend to meet any new situation by reorganising: and a wonderful method it can be for creating the illusion of progress, while producing confusion, inefficiency and demoralisation."

Thanks a lot jhwurmbach, I was trying so many things, but finally found your reply apt and exact. LineFromChar worked perfectly.
Thanks a ton.

CFont::CreateFont(...) and then CEdit::SetFont(...)
|
|
|
|
|
For example:
CPoint*pc=new CPoint;
//delete it in an array way:
delete []pc;
is the delete harmful?
if it is harmful, I have to add a flag in collection to record which pointer is for single object as example above or for array.
|
|
|
|

Yes, this can lead to troubles because allocating an array is not the same as allocating a single instance. For the array, there is first the number of instances that is saved just in front of the allocated memory. So, using delete[] it will try to read the number of instances first.
But why use a flag ? In your case you know if you use new or new[] (and normally you always now that).
If you do this:
CPoint* pc = new CPoint[1];
This is the same as allocating an array thus, delete[] will be ok.

wrong way! you have to create that the array way before deleting!
