There's no method in C# to position a MessageBox.But in C, you can position a message box by finding the message box and moving it. In this tip, I'll tell you how to position a MessageBox in C#.

15. When attempting to create a setup program, iget the error 'File BinSetup.exe not found'.
16. How to use assembly (ASM) with Dev-C++ ?
1.When I compile my dos program and execute it, Dev-C++ minimizesand then restore in a second but nothing appears ?
When creating a console application, be sure to uncheck “Donot create a console” in Project Options (when working withsource files only uncheck “Create for win32” inCompiler Options).
Auto tune apps.
2.When executing my dos program, it closes automatically. How I canchange this ?
You can use an input function at the end of you source, like thefollowing example :
#include<stdlib.h>
int main()
{
system(“PAUSE”
return0;
}
3.After linking, i get the error“C:DEV-C++LIBlibmingw32.a(main.o)(.text+0x8e): undefinedreference to `WinMain@16'
You probably haven’t declared any main() function in yourprogram. Otherwise, try recompiling a second time.
4.When I launch Dev-C++ i get the message saying “WININET.DLLnot found” ?
If you are missing WININET.DLL on your Windows system, you candownload it at:
5.When I compile a file, I get a message saying 'could notfind <filename> '
Check in Compiler options if the direcories settings are correct.With a default setup, you should have :
C:DEV-C++Bin
c:DEV-C++Include
c:DEV-C++Include
c:DEV-C++Lib
6.The EXE files created are huge. What can i do to reduce the size?
If you want to reduce your exe file size from 330 Ko to 12 Ko forexample, go to compiler options. Then click on the Linker pageand uncheck 'Generate debug information'. This willremove debugging information (if you want to debug, uncheck it).You can also click on Optimization page and check 'Bestoptimization'.
7.Under Windows NT, every time i launch Dev-C++ i get the message“Failed to set data for”
The is because you are not in Administrator mode, and Dev-C++tries to write to the registry. To get rid of the error message,log on as the Administrator, or uncheck the file associationoptions in Environment options, Misc. Sheet.

8.when I try to compile I get: ld: cannot open crt2. o: No suchfile or directory. What can i do ?
Go to Compiler options, and check if the Lib directory iscorrectly set to:
C:Dev-C++Lib
(for a default installation).
If this stilldoesn't work, try copying the file Libcrt2.o to your Dev-C++'sBin directory.
9.How can i use the OpenGL library and others ?
All the libraries that comes with Mingw reside in the Libdirectory. They are all named in the following way: lib*.a
To link a library with your project, just add in Project options,Further option files :
-lopengl32
This is for including the libopengl32.a library. To add any otherlibrary, just follow the same syntax:
Type -l (L in lowercase) plus the base name of the library(filename without 'lib' and the '.a'extension).
10.When i compile a file that contains references to Windowsfilename (like <Mydirmyfile.h>), i get a 'unrecognizedescape sequence' message ?
The Mingw compilerunderstands paths in the Unix style (/mydir/myfile.h). Tryreplacing the in the filename by /
11.Is there any GUI library or packages available for Dev-C++ ?
You can downloadextra packages for Dev-C++ at http://www.bloodshed.net/dev/
12.I am having problems using Borland specific functions such asclrscr()
Include conio.h toyour source, and add C:Dev-C++Libconio.o to 'FurtherObject Files' in Project Options (where C:Dev-C++ is whereyou installed Dev-C++)
13.The toolbars icons are showing incorrectly.
On some screenresolutions, toolbars icons may show up incorrectly. You shouldtry changing your screen resolution, or disable toolbars from theView menu in Dev-C++
14. It seems i've found a problem/bug thatis not specified here. What should i do ?
First, you shouldtry doing a 'Check for Dev-C++ update' (in Help menu)to know if a new version has come that may correct this problem.If there are no new version or the problem wasn't fixed thenplease send an email describing the bug to : webmaster@bloodshed.net
15.When attempting to create a setup program, i get the error'File BinSetup.exe not found'.

16.How to use assembly with Dev-C++ ?
The assembler uses AT&T (notIntel). Here's an example of such a syntax :
// 2 global variables
int AdrIO ;
static char ValIO ;
void MyFunction(.....)
{
__asm('mov %dx,_AdrIO') ; // loading 16 bits register
__asm('mov %al,_ValIO') ; // loading 8 bits register
/*
Don't forget the underscore _ before each global variable names !
*/
__asm('mov %dx,%ax') ; // AX --> DX
}
This topic describes how to create, add items to, and retrieve items from a simple combo box. Specifically, the accompanying code examples demonstrate how to perform the following functions:
- Dynamically create a simple combo box in a parent window.
- Add a list of items to the combo box and display an initial item in the selection field of the combo box.
- Detect when the user has selected an item from the combo box.
- Retrieve the selected item from the combo box.
What you need to know
Technologies
Prerequisites
- C/C++
- Windows User Interface Programming
Instructions
Step 1: Create an instance of the combo box.
The example application calls the CreateWindow function to create a child window of the application window. The WC_COMBOBOX window style specifies that it is a combo box.
Step 2: Load the combo box with the item list.
The application sends a CB_ADDSTRING message for each item in the list. After the list is loaded, the application sends the CB_SETCURSEL message to display an initial item in the combo box selection field.
Step 3: Detect when the user selects an item and retrieve it from the combo box.

When the user makes a selection from the list, the combo box sends a CBN_SELCHANGE notification to the parent window via a WM_COMMAND message. The application retrieves the handle to the combo box from the lParam field of the notification message and sends a CB_GETCURSEL message to the combo box to retrieve the index of the selected list item. After obtaining the item index, the application sends a CB_GETLBTEXT message to get the item. It then displays the item in a message box.
Note
The CBN_SELCHANGE notification is sent and processed before the item is placed in the combo box selection field. As result, in this example, the selected item won't appear in selection field until after the message box is closed.
