Since DLL is based on Win32 api ,you can Dynamically load the Function from That DLL using LoadLibray and GetPRocAddress.
but one thing that buggin me is that From VB only you can craeet a COM DLL not a Simple Plain dll,(yeah i known you can create a Simple WIn32dll,but that not common that need special DLL Compilers).

Hello. Does anyone have experience in inserting an image as background in an editbox? I've tried, but the final solution took up a lot of cpu. I just want the editbox to look like those in Msn messenger.
If it isn't possible to do ownerdraw with an editcontrol, which control must I then use?
-Anders.

One method would be to owner draw the editbox and handle WM_ERASEBKGND
by painting the image.

Thanks for the reply!
I've tried handling WM_ERASEBKGND, but when WM_VSCROLL is called, the background image moves down like 10 pixels and then jumps right back up. I don't want it to scroll down, so this is fine(that it jumps up), i just wonder how I can stop the scrolling from pulling it the first 10 pixels.
To do this I used LockWindowUpdate(), but this took up an awfull lot of cpu 
Any suggestions as to how I can stop the scroll-messages from scrolling my background? Or am I using the wrong approach?
-Anders.

when we right-click a file in Windows explorer, a popup menu pops up with several apps, e.g. "Edit with Visual studio"
I want to add my app on the popup menu, so when users click a kind of files, the files can be edit by my app.
I know how to use double-clicking - I need to add my app to popup menu.

Hi
you can do this useing registry(regedit.exe)
normaly any Dim for any file have key in registry in HKEY_CLASSES_ROOT key.
open registry and then see HKEY_CLASSES_ROOT open it see
key txtfile it has the follwing keys
->DefaultIcon
->shell ->open ->command "full path for you program on this case %SystemRoot%\system32\NOTEPAD.EXE %1"
->print
-printto
now see open key this word appare on any file when it has
extenssion .txt .
and command key used to determin the path for the program can open this files
you can use registry API function's to work with registry
to create new class in registry and to add your keys.
On Earth nothing impossible,
while your mind running.

Hi all,
I want to make desktop sharing software which accesses other computer's desktop from my computer. Does any body have idea about this? how to start?
Is their any code/articles present on any site?
I think you got the idea i want to do ?
So please help me?
Language can be .net or vc++

Yeah, here is your IDEA
hope you like it.
#1 As it is network application ,so you have to depend on WINSOCK for transferring data.
#2 now for Seeing Desktop of other computer you have two ways
->either Transger Desktop image per mili second to other computer to show real time image. one major disadvantge is that network usage is so high that it will choke the network,you can visualize by thinking of three computer is sharing ther desktop woith other computer.
->more efective way is to hook wmpaint message, retrieve dta afrom it and send it to remote application.
#3 last but not the least, simulating keypress and mosuse movement to particular window.
this can be achive easily using WINDOW MESSAGES like WM_CHAR and Mouse Messages if you have handle of particular window.
for that this api will help you retieve the particular window handle
WindowFromPoint(stPoint);
ChildWindowFromPointEx();

I would like to develope an application in Win32, once run it should stay running and POPUP, when I press Special Keys i.e. Ctrl+Alt+R. Any help is highly appreciated.

Yeah this can be successfuly accomplish using HOTKEYs
Use this api
RegisterHotKey
The RegisterHotKey function defines a system-wide hot key.
<br />
BOOL RegisterHotKey(<br />
HWND hWnd,
int id,
UINT fsModifiers,
UINT vk
);

I could not find anything about:
desktop intercative services in CodeProject.
I use the function like:
iStat = RegisterHotKey(hwnd,77070,MOD_CONTROL && MOD_ALT, VK_R);
But I get 'VK_R' : undeclared identifier error?
Will appreciate a sample code.

use this
RegisterHotKey(this->m_hWnd,77070,MOD_CONTROL|MOD_ALT, 52);
or visit http://www.voidnish.com,it has good example For HotKey

You look for Services first,DESKTOP_INTRECTIVE_SERVICE is just Argument passed to CreateService when we create Service.
advantage of Desktop Intercative service is that it can interect with desktop.
you can also go for Hidden Dialog Application ,whichpopup on register Message

Dear Mr. Alok Gupta,
Thank to you and Void Nish, the HOTKEY is Done.
I studied services.I want my application to be in "Windows Notification Area" like MSN Massager. Should I study Services or CreateProcess, or something else?
Please Note, my application will run on win 9x/2k/XP.
Is not good to not know, and is worse to not ask!

HttpRequest->open("POST", "http://web.cgi", vAsync, vUser, vPassword);<br />
HttpRequest->setRequestHeader("Content-Type", "application/x-www-form-urlencoded");<br />

IS your Webserver provide support for Posting data from application.
Returning OK means that The Url you requested is Found,this Ok dosn't tell any thing about the your data posting is successful.
data posting always come witha html file in return,try to read that file,it may contain possible error description

_bstr_t bsResponse = HttpRequest->responseText;
The above line contains the contents of the HTML Page.
But the problem is that It only contains first few lines.
The tag is not even complete in the string.
Dont know how to get it.
Can it be done thru some other way.

Hi experts,
I found a really easy example on how to create a dll to hook the open/save dialogs to customize, but it says to "call it from VB", but I don't have Visual Basic installed, I'm using VC++ 6.
How do I create a simple application to test the dll in VC++? I've tried all the tutorials here which all work great for those examples, and searched forever on Google, but I keep getting errors no matter what I try for this particular project.
I'm a real c++ newbie, please help, I'd be so grateful.
