View 9 RepliesI have a filter that is used to populate a grid view and the url will conain: /example/grid?value1=1&value2=2
It will then have a link to page 2, which allows them to edit something.I then want them to click a link that will send them back to the gridview under the same parameters of: /example/grid?value1=1&value2=2
Is this possible? How do I hold on and fill in the URL values so it knows how to refill the grid view accordingly?

I know how to send mouse clicks and keystrokes into an application when it is open and active, but this particular application the task is very repetitive and can be done with a script of sorts. What i want is how do i make a program to be able to send inputs (key clicks) into the application when it is minimized (the application minimized that is). doing this minimized would then allow me to do other more important things whilst the vb program is sending instructions into the other app.[code]...
View 24 RepliesI have a VB.NET application that uses Managed DirectSound to capture audio.Everything works just fine until (a) the application is minimized or (b) the application is completey obstructed (covered) by another window.
The thing is that the CaptureBufferDescription structure does not include a GlobalFocus property so I don't know what to do to let my application continue capturing when the main window is hidden.
Here's the basic initialization code I'm using:
' Create a buffer description object

I'm trying to make use of some functionality from an external app in my program.
My problem is this:
My program manages to start the external app correctly and I can even get the WinHandle correctly if I don't use "ProcessWindowStyle.Minimized" when starting the app.
If I start the app minimized, WinHandle = ProcID.MainWindowHandle returns a 0 and as I understand it, it's
because the app is hidden in the system tray.
How can I start the app minimized and then get the window's handle once it has been minimized?
I've tried various functions like FindWindow and BringWindowToTop but none of them seem to work.
im a complet noob in vb . i have been trying to figure out how to send keystrokes back to my own application , while minimized/ Or focused on an other window.i think i need to use PostMessageA . i read about it on forums. But its like chinese for me.my goal is to run these little programs by the 100's on 1 pc. and they just press a key in their own application , over and over.i was thinking something like this
Private Declare Function PostMessage Lib "user32.dll" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Private Const WM_CHAR As Long = &H102
PostMessage("notepad", WM_CHAR, "T", 1)
currently my VB Skills aren't so good so bare with me here. application to be able to send keystrokes to another without having it popup. Like it should remain minimized, it shouldn't interfere with whatever you are doing on your PC while it sends the strokes. I received this request from some one else to do. So basically I just need to get focus to the application while it remains minimized and send keystrokes.
View 4 RepliesI have an issue in a project trying to auto-scroll down a ListView (used as Details with columns) when adding a new ListViewItem when the window is minimized. I guess we have to use TopItem property to set force the listview to scroll down.I get two exceptions when the form is minimized: "Object reference not set to an instance of an object." "Index (zero based) must be greater than or equal to zero and less than the size of the argument list."

I'm trying to send a keystroke to a window (of an external executable) but am having problems.
If I launch the exe with a window I can successfully send it a "q" (in order to make it exit) using the follow:
1) AppActivate and SendKeys
2) SendMessage API using WM_KEYDOWN and WM_KEYUP
3) AppActivate and keybd_event or SetForegroundWindow and keybd_event
However, if I launch it without a window, obviously method 1) does not work as SendKeys only work on applications with visible windows, but I thought that method 2) would work. However, it doesn't. Also, using method 3) with SetForegroundWindow as this seems to only work with visible windows, which is not really a surprise I guess, given the name.
Another method I have tried, which won't work is using the RedirectStandardInput - I have this working correctly, but the application is looking for keyboard events, not writes to its StandardInput stream, so this doesn't have any effect.
Finally, I have tried using SendMessage and FindWindowEx, and TranslateMessage, to find any child windows or controls that should be receiving the messages, rather than the main window. However, no child windows or controls are found, and I wouldn't have thought this would be the solution given that, if the window is present, the main window receives the message as it should.
So, I have confirmed that the messages are going to the correct window, as they arrive as they should when the application is launched with a window, but I cannot get the application to receive the message when it is window-less. The solution doesn't have to involve messages, or even be particularly robust, but this is what I have tried so far (all the obvious stuff!)
I am trying to code a program to send keys to a certain window.
For example, in notepad I want the program to write "test" over and over again, in the notepad window. However, I do not want this window to be an active window. Is it possible to make it send keys through a background method?
Want to send the text from my current vb application to the Active Window and that text should be displayed in the text area of the active window.
View 1 RepliesHow do I make the form send keystrokes such as Tab, Enter, Left Arrow etc to itself without interfering with other programs? If I use the SendKeys.Send method, it would send it to whatever window is opened. Is there a way to only work with the form? Very quick random example: Let's say I have 5 textBoxs and I click the 'Tab' button 5 times. What would happen ?
It would change the focus from one textbox to another right? Can I make this happen automatically ... like make it happen in the background and only to the form itself. So If I'm typing something on Notepad, I don't want to receive those 5 tabs. By the way I know I can use this code to change the fofucs, but remember its only an example.

I need to have a VB form that runs out of focus behind another program. When I press "A" (I'll use "A" and "B" as my example keys), "B" is then sent to the program in focus from the VB form and held until "A" is pressed again.
I've worked out how to get it to repeat a key press hundreds of times but I need it to HOLD the key, rather than to just Press and De-press countless times.Here's the piece of code which repeats the letter "A" 100 times:
Dim Index As Integer 'My count variable
For Index = 1 To 100 'Count from 1 to 100

View 13 RepliesI'm trying to send a single keystroke to an application that has no window (because I have launched it with StartInfo.CreateNoWindow = True) and therefore I can't use SendKeys. I had a look at SendMessage but this doesn't seem to be quite right as the programme I'm sending it to doesn't process message queues.I would usually use the StartInfo.RedirectStandardInput property and send it via a StreamWriter but this doesn't not work as the application it is being sent to is looking for actual keyboard keystrokes, rather than pulling info from StandardInput (an old C++ programme using getch). Anyone have any ideas how to send a keystoke to an application with no window (FYI I don't need anything back from it, I don't need to wait until it's processed, and I only need to send one letter and no carriage returns or linefeeds, though these wouldn't hurt)

I have an interesting issue, I'm trying to automate a data retrieval process.Currently the user goes out to a secure web site and inputs his/her username and password and then selects the ok button, they then proceed to the location where the data is located at and do a copy and paste. I have thought about using the SendKey method from VBA but everything I see says it's not reliable.I believe I have the section after the sending of the login/password completed. For the life of me I can't figure out how to automatically input the username and password and then select the "OK" button. Before anyone asks, no can't view the source code so I can't get the ID field, there is no way for me to view the source code at all I have tried multiple different options all with no luck.

But once it went to the back, everything works... cursor.position moves the mouse, sendinput and mouse_event can click on a different window, just not the one i want.
