i used an old VB6 algorithm to subclass a window and made a few changes at the 'hook method' to make it work in .NET.
Private Declare Function SetWindowLong Lib "user32.dll" Alias "SetWindowLongA" (ByVal hWnd As Integer, ByVal nIndex As Integer, ByVal dwNewLong As delWindowProc) As Integer
[Code].....
Is there a way in vb.net to subclass/hooking in to any controls scroll bar and change it is colours etc (I saw this once in C++ but lost it). It�s ok for MS giving us user owner drawn controls, or at the very least allowing us to draw the controls information but it looks dam write awful if the scroll bar does not fit into the GUI.
View 8 RepliesThere is a class in this datalayer that subclasses System.Data.Datatable. So for example if I populated a System.Data.Dataset and then tried to put the first table of this dataset into this class like so:
Code:
Dim dt as new myDatable
dt = ds.Tables(0)

I want to create a subclass of a class that has some shared methods. These shared methods all call one specific method. But I can't redefine that specific method in the subclass. If I try to make it overridable in the parent class, it says that shared and overridable can't both be used.

I'm listening for the WM_SETCURSOR messages and setting the cursor there, it works most times, but not always. I've seen two other cases that I need to catch:
WM_PAINT: At least after a WM_LBUTTONDOWN the cursor is painted somehow without calling WM_SETCURSOR... WM_CAPTURECHANGED: Happening sometimes when the mouse is down and moving it.
Even doing all this the cursor sometimes flickers and the original one can be seen in some cases (eg: the instant when you roll over some object that sets the cursor to something else). I've been trying to look for some other patterns or messages but didn't see anything that would solve this problem.
How would I get a window's process name? For example, if im using firefox, and im on VBForums, I want my program to look for a window with a name of "VBForums - Visual Basic and VB .NET Discussions and More!" and then get its process name.

what I am trying to do its to automate a user interraction by code.First I have a button named "start" once pushed I navigate with webbrowser to download a file. What I try to do it is to find the window "File download" by his title name, I allready made a seperate thread to loop into to list of process until it found the window "File download"
Where I need help, it is with the process list. I try that code below but I don't see the process "File download" in the list.and once I found it I would like to use sendMessage() api to simulate the click of save.I would like to find another window after to catch the window "save as" and click save and if the window that ask for overwriting appear I would like to find it too and click yes.
Why I use webbrowser instead of httpwebrequest it is because the web site required to login, i try using cookie, etc. No success so I decided to use webbrowser, I navigate first into the login page, I login manually and once it is done I can click the button to start downloading. I want to make an automatic download loop, I have lot of files to download on that site, sometimes .doc and other times it is .pdf
I didn't found a way yet how to force webbrowser to ask for downloading .pdf instead of opening it in acrobat, if someone can help me for that point too

I am making a key presser for a game and I have it to just spam the keys, but I want it to send the keys to a certain process or window. Here is what I have:
Private Sub Timer8_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer8.Tick
SendKeys.Send(1)
SendKeys.Send(2)
SendKeys.Send(3)
SendKeys.Send(4)
SendKeys.Send(5)
SendKeys.Send(6)
SendKeys.Send(7)
'#7 in box'
That's an example of 1 timer. Is there any way to make it just send the keys to a process I am kinda new to this.

I have 2 desktop programms..I will call them P1 and P2.So, P1 launches P2 as a process. However, at some point I want to be able to show a window in P2. My problem was that this window, when called, was showing correctly placed, in the middle of the screen, but in the back of P1.So, in order to show it as the top most window, above all others applications running on my computer, I used the windows API:
Const HWND_TOPMOST = -1
Const HWND_NOTOPMOST = -2
Const SWP_NOSIZE = &H1[code]...
Now the window shows on top of all other, but it is placed in the top left corner of the screen, resized to much small dimentions, that I cannot even see the controls on it.

I have this application that I haven't created and I don't have the source for. But it's really handy in handling and recording the time I've used on different projects. But it has this annoying pop-up that comes up that contains a window and some debug text I believe. It wasn't done by a professional, it was just a hobby project. Everything is working even though this window appear. So I was wondering if it's possible to "hijack" a window and minimizing or closing it somehow?
View 1 RepliesThe user32.dll provides functions to get the process id from a process executable name, and I can also obtain the active or foreground window that the user is working.Can I determine what windows the targeted process has opened? Otherwise, can I find out what details about the process that opened the foreground/active window?
My code needs to run only when another specific process is running and the user is actively using that window, while that window is the top-most window on the desktop.
I have an application that while running (it doesn't have to have focus, it can be minimized or another window can have focus) can listen and respond to global hot keys pressed. For instance I have the key combo Ctrl+Shift+0. When this hot key is pressed my app can recognize this and then I can do something.
This "something" that I want to do is:
1. Know what window is currently active and has focus when the hot key was pressed. And...
2. Change the size of said window
I can currently identify what window has focus by the following (the code block is inside the function that fires when the hot key is pressed):
Code:
Private Declare Function GetForegroundWindow Lib "user32.dll" () As IntPtr
Private Declare Function GetWindowThreadProcessId Lib "user32.dll" (ByValhwnd As IntPtr, ByRef lpdwProcessID As Integer) As Integer
[Code]....
I can get the handle to the active window and the process that owns that window.
Having this information, how can I get access to the window itself? Furthermore, get access to it's properties so I can change the size of this thing? I'm not sure If this is the right information to be gathering for what I'm trying to accomplish but it seems that I'm close.

View 2 RepliesWe create a window service that will launch multiple process of an application with different configuration. And application further communicate with sql server. It works fine when we start service manually from service manager. It launch all the process ( try with launching 3 process ). But when we test it by restart the machine and service launch automatically then it launch only one process third one. I check the event log in event viewer. I see the following message by MSSQL$MSSQLEXPRESS service
Login failed for user 'dduser'. Reason: Failed to open the explicitly specified database. [CLIENT: <local machine>]
one thing we also tried by delaying ( with thread sleep ) the code execution of service. Then by starting machine again , it launch 2 process , first one still not launch.
I haven't programmed in Visual Basic before. I downloaded the 2008 Visual Basic and I'm trying to write something that activates the frontmost window of the parent process. I realize that there's a few steps... find the parent process, get its first window (z-axis wise), then raise that window even though it currently isn't the active program.
I've found some example code on the net, but none of it compiles, even code I found at Microsoft. I'm guessing that it's all an older syntax that's no longer supported. [code]...

View 10 RepliesI would like to launch a command line exe I created. For now it's a test program that writes Hello World to the console. I can launch it, but the shell window it displays it in only stays for a split second.
I know I can add a line to my console mode program (readline). But I would like to control it from the process launch. I will be using console mode programs that I did not write myself, and many of them don't stall the output. I can't find the right properties and methods to control the default shell behavior!
