I am working in windows forms with Vb.NET 2008. I am trying to read text in from an external program. So far I have been able to read text in from a standard text box or button, however I am trying to read data in from an external data grid.
When I try to use the following I get no information about the grid
ChildHandle = FindWindowEx(ParentHandle, IntPtr.Zero, "classnameofexternaldatagrid", Nothing)
Dim Hndl As IntPtr = Marshal.AllocHGlobal(2000)
NumText = SendMessage(ChildHandle, WM_GETTEXT, 2000, Hndl)
Text = Marshal.PtrToStringUni(Hndl)
Usually if it is a standard text box I will get the text data with no problem, but it is a standard data grid and there are no further sub handles to try and read from. If WM_GETTEXT wont read information from an external data grid then how would I read in the data?
I have this application that I need to read a text file.
I have designed a form which has a play button and when the play button is called it is supposed to read a text file which has being created using an external application..
I wrote a code that calls the application but I dont know how to pass the text file into the application.
I also dont want the application popping up.
line of code that calls the application ---- Process.Start("C:Program FilesDECtalkUSsay.exe")
I'm working on an app that should be able to read files from an External Hard Drive or even an iPhone or iPod. I'm a beginner so it would be great to keep it simple :) I suppose I should use the SerialPort class? But I'm not sure and I couldn't make it work.

When I try to load the XML in a Datagrid,I am able to load the data under the "description" element properly, however when it comes to loading the data under the "production" element, only data for the last movie is loaded and is repeated for all 3 movies.
Below is the code i am using:
'-------Initiate the OpenFileDialog to load the Load XML file Dim x As New OpenFileDialog If x.ShowDialog = Windows.Forms.DialogResult.OK Then
I am currently working on a program that needs to execute an outside program and then remove the border from the program (The border that includes the minimize, maximize, and close buttons) and then embed it into my form. I have everything working except for removing the border. Anyone have some code to do that? I am using vb.net in VS2008.
I want to read in a file and as I do put the contents into a datagrid, can this be done ?I have the following code so far
myPath = "C:SYNC_DATA�0 - LGW�5 - Archived�0 - IST Logs2008" myFile = "istlog" & d.Year.ToString & d.Month.ToString.PadLeft(2, "0"c) & d.Day.ToString.PadLeft(2, "0"c) & ".txt" Dim sFile As System.IO.StreamReader = New System.IO.StreamReader(myPath & myFile)
[code]....
I get an error on "adapter.Fill(dt)" which is propably incorrect.How can I get the ontents to be displayed in a datagrid on the screen called "DataGridView1"
I have a datagrid which I have manually added columns to and adding rows at runtime (code I am using below if that helps in anyway). When that row is sellected I wish to get the data from different columns.
I'm adding to the grid:
Dim dgvRow As New DataGridViewRow Dim dgvCell As DataGridViewCell dgvCell = New DataGridViewTextBoxCell()
.DataSource = dsAuthors .DataMember = "authors" End With
However, it will not allow me to reference .DataMember, it keeps popping up with the error text "'DataMember' is not a member of 'System.Windows.Forms.DataGrid'". What can I do to resolve this error? Or how else can I read into the DataGrid?
Note: I have the most recent Framework installed with Service Pack 1

So I have my form, I add one combobox (combobox1) and a button that says "Launch..."Button 1's
Process.Start(ComboBox1.SelectedItem)
When you select a program from the combobox (combobox1) and click launch, it launches that program, for example, cmd.exe (command prompt) when I click the button, it launches the command prompt, but if I select a game (for example chess.exe, for vista), it says it can't find the file, this is because the search for the file is only: WindowsSystem32, how can I change that? OR, how can I add a reference that searches the WHOLE Disk, not just WindowsSystem32?
I am using VB 2005. I am trying to open an external program, make it invisible, and then control it. It is fine if the external program shows up in the Windows Task Manager, but I don't want anything showing up in the Windows taskbar. I already know how to open the program I want to use. For that I am using:
I start an external Program using System.Diagnostics.Process.Start I want monitoring when a user has started a new file, saves or opens another file and get the info of the file in current process
So, I'm using shell to start up an external application at the press of a button, but the application requires several other external files with it in order for it to work. How could I make it work? Note: I'm a newbie
i wanna know how to launch an external program as administrator Like tick a tick box and it launchs the program as admin if you tick it and push the button.
What I'm wanting to do is gonna sound pretty strange. I play a game called Wonderland Online. Usually while playing, I will have between 3-4 instances of the game going at the same time, each instance running a different character. Also, I will have open another program that I wrote that helps me figure out what I need to manufacture a certain item in the game. The running game is an 800x600 window, and I have all 5 of these windows open at once, where I am constantly moving things around, minimizing and maximizing.I want to create a app that would basically be a frame for the game. Creating the frame would not be hard, but this is the first time I have tried to get an external EXE to basically run inside of my program. Is this even possible? And if so, I would imagine I could run multiple EXEs and flip between them inside my frame. I could integrate my manufacturing program into the frame, as well as control which instance of the game is visible inside the frame.
Some time ago I saw a code to host an exe from within a visual basic form, acting as its parent. How would I go about doing this in vb.net? I havent programmed in ages, but recently have gotten an interest again in order to complement

The drive is connected via USB and the problem I'm having is that, periodically, while my code is executing, the usb drive seems to disconnect and reconnect. (Nothing to do with the program, but the drive itself).I want to find a way to prevent these temporary drive reconnects from interrupting my code. IE, i want to insure that whatever read or write that is requested is actually executed even in the case of a temporary drive interruption.
I'm trying to write a vb.net application that works with a 3rd party application called FuzzyTech. Unfortionalty FuzzyTech is quite old so the only way I can interact with it is buy using DDE. FuzzyTech acts as a DDE server. After a bit of research I found a library called NDde which enables me to use DDE. I understand that vb.net does not natively supprt it as it is an old technology.
Now fuzzyTech seems to only respond to the DDE connect and pokes when in debug mode. The only way I can find to get the program in to debug mode is from the menu bar (Debug > Interactive). So I have written an application that runs fuzzyTech, grabs the window and then accesses the menu to put it in to debug mode. My code can then use DDE. I have all of this working ok (although it does feel like a bit of a hack). The problem is I don't want users to be able to see this happening.
I want fuzzyTech to be hidden.After more research I found I could hide the window on startup by using fuzzypProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden. However when I do this my code to grab the window and send the menu commands then fails. I think this is because the window title becomes blank when hidden.So I need to know a way of controlling the program after it is hidden or hiding it after it is in debug mode. This is where I am stuck. I'm very new to programming and this has got me completely stumped.
Here is some of the code I am using:
Private fuzzypProcess As Process = New Process() Private Sub LoadFuzzyTech() Try fuzzypProcess.StartInfo.FileName = projectPath & projectTitle & ".ftl"
I can launch my external program which is a Virtual Keyboard, but once it launchs then I have to click the textbox on my form or no text appears when I use the Virtual Keyboard. How can I make my form be the focus after the Virtual Keyboard launches?
The VB.Net program in question creates several files, adds them into a zip file (using DotNetZip), and saves the zip file into a given directory (which the user chooses). This comes out just fine. But when I use it to save directly to my USB flash drive, I can't eject the drive without shutting down the program first.I've tried disposing the zip object (from the DotNetZip library), doesn't work. I also tried setting FileIO.FileSystem.CurrentDirectory to somewhere else on the machine, still no.
I have a program that I am working on and I would like to have it embed and run an AntiVirus program , but I am not sure if this can be accomplished with the use of a button.
