I am using SendKeys.Send("{HOME}") in a MaskedTextBox to bring the cursor to the beginning of the textbox when the text is empty. When I try to close the project the application freezes if it doesn't have focus. How do I put this application in focus before I call SendKeys? [Code]
View 2 RepliesAt the moment I have this to change focus of an element:
SendKeys.Send("{TAB}")
Instead of using that I was wondering if I could do something like this:
WebBrowser1.Document.All("id").InvokeMember("click")
But to get focus to the next element in line, like the next one from the current focused item.
First I say tx to Dream.In.Code, ex. CharlieMay, who have solved all my problem. Now this is not problem to me. only I dont know, how focus to next currentrow without go to down first! because of this , my coding must include SendKeys {UP} else it go to down
CODE:
How to make SendKeys or corectly my coding, for not show in display like this?

This isn't really a VB specific question. It's .Net in general... if you have ideas in another .Net language, let me know... I know most of the .Net languages (I don't know that foxtrot or what not weird ones). Furthermore this isn't a 'I don't know the method on some class I should be using' kind of question, it's a design/problem solving kind of question.I'd like to know how you'd approach the problem with in the boundaries set.

I have an WPF full screen application and I configured Skype´s "Focus Skype" Hotkey to Ctrl+F6 combination.
How can I send this message to windows (Ctrl+F6)? I tried by sendkeys but is not working, it says that: SendKeys cannot run inside this application because the application is not handling Windows messages. Either change the application to handle messages, or use the SendKeys.SendWait method."
I tried Sendkeys.sendwait method but it minimized my full screen application and I need it remains full screen.
I've been developing applications in VB 6 for many years. For a long while now I've not been developing and I switched over to Windows 7. Now I've been asked to build a trainer so I moved over to VB.net 2010 and I'm struggling to make the transition. Anyhow I'm stuck with this trainer.I've been asked by many players of an online game to create an application that serves as a trainer for leveling up characters. I've been personally approached by some of the guilds also. This is an MMORPG so instead of running around for hours, the trainer simulates the keyboard key 1 being pressed which is the attack button. So the character attacks monsters automatically until you stop the trainer. In this way you can leave the game running in the background and do other work.This small project has got me really excited in working in vb 2010 and to me it's a small kick start. I haven't done anything like this is Vb6, it was more database orientated and educational game software I was developing. So I'm clueless in this area.
It doesn't really work. If I activate the ingame chatbox it returns 1 and 49 respectively into the text area but doesn't activate the "attack" command even if the chatbox is deactivated. I'm guessing it's not sending the keyboard press event but instead sending a string?
So I have a form with a textbox1 thats supposed to enter in a set of keywords and then ebay will give you the"Instant suggestions" in return, but when I have my textbox1.text send the text over to the ebay form, ebay will not return any suggestions, unless I use the sendkeys.send method. Well, I do not like the sendkeys.send method because it's way too buggy &only works under the right conditions.Here's a pic of google instant and ebay does the same thing. So here's what I'm trying to get ebay to do:Here's the code that I have:
Dim theElementCollection As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("input")
For Each curElement As HtmlElement In theElementCollection

View 1 RepliesI cannot find any solutions so far using the MSDN search, so I'll just ask the question here. I am trying to make a "bot" so to speak for a game that I play so that I can automate movements and macros. I've never used Sendkeys method yet until today so I am very unfamiliar except for the articles I have seen on the MSDN.
Basically, the game I play I can manually set macro keys like spacebar to perform task. What I want to do is have my application automate this process on a timed basis. Like, every 2 seconds send the key of spacebar to the other application (MapleStory.exe).
[Code]...
I have a specific application (someprogram.exe) i wish to use the sendkeys command to perform CTRL + C from the application i'm bulding in vb.net. I don't need to bring the data into my app, just copy it to the windows clipboard.
View 1 RepliesI am automating 3rd party simulation software. The simulation is contained in a DLL. The DLL is programmed to interface though Excel. (Yes I have tried to use the dll outside of Excel, but other factors don't allow it. I have also asked the author to capture the error and recompile the dll)
VB.NET Application
- Excel.exe
-- Simulation.dll
Sometimes a runtime error occurs in the DLL and a dialgo box is created. "On Resume Next" in excel does not bypass the error, nor can I trap this error in the VB.NET application. Currently, if the simulation does not complete in 5 seconds (the DLL error has been thrown and a dialog box is present), I terminate excel application in the following pseudo code manner:
1) Excel.Quit (quit method of the Excel application object model; does not close excel, no error thrown)
2) FinalReleaseComObject() (for all the object references to Excel, workbooks, ranges, etc) <- a
3) Set all excel references to nothing
4) System.Diagnostics.Process.GetProcessById(MyClass.procID).Kill()
A RaceOnRCWCleanup is detected (An attempt has been made to free an RCW that is in use. The RCW is in use on the active thread or another thread. Attempting to free an in-use RCW can cause corruption or data loss.) when releasing the Excel application (the other object references do not cause this warning). Is this caused by Excel still being open? I have tried to "find" the error dialog box and close it with some SendKeys, but the an System.InvalidOperationException is thrown: SendKeys cannot run inside this application because the application is not handling Windows messages. Either change the application to handle messages, or use the SendKeys.SendWait method.
I have tried:
1) MyClass.xla.Dialogs.Application.SendKeys("{ESCAPE}")
2) MyClass.xla.Application.SendKeys("{ESCAPE}")
3) MyClass.xla.SendKeys("{ESCAPE}")
4) System.Windows.Forms.SendKeys.Send("{ESCAPE}")
5) My.Computer.Keyboard.SendKeys("{ESCAPE}", True)
6) sending keystrokes to buffer: [URL]
7) Creating a VBS file to send the escape character (doesn't work becuase of the path lenght)
This is what I know about the dialog box from Spy++:
Caption: run-time error
Class Name: #32770 (Dialog)
This program will be running un-attended so I want all debug errors and messages accounted for in code before this goes into production.
What is the difference between SendKeys.SendWait and SendKeys.Send?Send obviously will just send they key immediately, but does SendWait actually wait for the message to be processed or does it also send it immediately?The function's name itself is just confusing. Which one should I use if I want to send keystrokes to a 3rd party app immediately, or is there no difference? To me, a few milliseconds is a big difference.
View 3 RepliesI have an issue regarding Sendkeys Class, as i want to use this class in order to send some keystroke to the active application. As a first step i want to test the {Enter} keystroke, so in order to achieve that i made a simple application in vb.net 2010
Public Class Form1
Public Shared data As String
Private Sub SendintText(command As String)
[Code].....
By the way in order to use double quotes in a parameter you need "test"...(i have spent 15 min to find out) so it might be usefull...
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
CheckBox1.Checked = True
While CheckBox1.Checked = True
SendKeys("{END}")
End While
End Sub
That is the code, the error is "SendKeys is a type and cannot be used as an expression."
I have tried to control another application to automate a process we do 100 times a day. It is simple enough, a few key strokes is all but I have been foiled in all attempts

View 2 RepliesI'm trying to use the sendkeys method SendKeys.Send(
[code]...
Function to copy whatever the user has highlighted. I have a console ap with hotkeys to open it. It locks up the computer and I have to use TaskMan to free it up. I know this is a simple piece of code but I must have something wrong with the sendkeys line.
I'm looking for the underlying Win32 API call that the DotNET Framework invokes on a SendKeys.Send or .SendWait call, or a Win32 API Equivalent to SendKeys. I've already experimented with SetKeyboardState which seems like the way to go, except that it does not raise any kind of keyboard event that causes the set keystates to register with an active application or the OS (at least not until another key is pressed; for example I can meddle with the keyboardstate before events process on a natural keystroke, but I can't invoke a keystroke programmatically).
View 1 RepliesI have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?

I have a VB.Net 2.0 application, on my form I am using a Component ONE PDF reader control.I am trying to send to this control a F4 keystoke to close the navigation panel when it opens the PDF file. It is not working or not accepting the sendkey.I put focus on the control first. Code below:

My.Computer.Keyboard.SendKeys("{F4}", True)
I have tried different variations of the Sendkeys with no success.
In my windows application, the first form is login form. When the user double clicks my application, the applications icon flashes in the taskbar though the cursor is in the username textbox. The user then again should use the mouse to turn the focus to the login form. But however while i am working with the source code its working just fine
View 7 RepliesIn VB.NET, you can set focus to an external application using
AppActivate("Windows Name")
or
AppActivate(processID As Integer)
Now this works fine if you do for example:
Dim intNotePad As Integer = Shell("C:WINNTNotepad.exe",
AppWinStyle.MinimizedNoFocus)
AppActivate(intNotePad)
But when I do:
For Each theprocess As Process In processlist
If InStr(theprocess.ProcessName, "DWG") Then
strProcessList += String.Format("Process: {0} ID: {1}", theprocess.ProcessName, theprocess.Id) + vbCrLf
AppActivate(theprocess.ID)
[code]....
then it doesn't find the window, even if it's open and even if it finds the window using the window title.But I need it by process ID.How can I do that?I need it to set focus on a 3rd party installer in a windows installer setup project.
I'm trying to make a WM6 version of this simple windows app, and I have some certain problems. Under a timer event I have several instances like this (don't ask why timer and why this way, it just works in my case):
Code:
If ent1.Focus = True Then
ent2.Text = Math.Round(((ent1.Text) * 3), 1)
End If
[Code].....
It didn't work under WM6 so I've changed it to ent1.Focus.
Anyhow, the problem is that under WM6 focus is jumping around with the timer, i.e. different textboxes become active every timer iteration making it impossible to work with the program.
I am using VB.NET to build my application. And in my application has a lot of Forms. It doesn't use MDI Parent Form, but I use another simple Window Form (I named it frmMain) that I suppose it is my MDI Parent Form. When frmMain load, windowState = Maximized. And when I open a Form (example: I named it frmCustomer) that I suppose it is my child Form, and I set its properties (frmCustomer.TopMost=True) when it load, so it always on the top. But When I change to open another application such as Ms. Word or Mozilla Firefox... the frmCustomer is still on the top. how can I know my frmMain lost focus?
View 1 RepliesI have been working with the Notify Icon to make it easier for some who prefer minimizing an application into the notification bar rather than the task bar. I have a drop down item that allows the user to Show in Notification area if checked. If it's not checked, then the form reverts back to default with the task bar. However, when this is checked and I minimize the form, I can not open the form from the notification tray. The problem is when the notify icon is visible and clicked, I need it to run code. If the form is minimized, I want it to show the app when I click the icon.
