C# - Get Form Source File At Runtime From External Process In .NET?
Apr 30, 2011
I am currently working in a very large solution (120+ projects). Very often, we need to find a particular form in a large desktop application, consisting of hundreds of forms. For example, we might have a requirement to edit some controls on a certain form.We don't know the form name, but we know how to navigate to the form when running the application.
In order to identify a form, we currently try to find some unique text on the form, and then search all the source files for this string. That's not very cool.Instead, I'd like to make a little tool that can identify the source file for a form, or at least the name property of the form object. We can't add code to the solution itself, so we will have to make an external exe.

I am creating a visual basic program, which acts as a very simple GUI for another program. I have built the whole Visual Basic project, but I am unable to do one part, the most important part you could say. I have a button (button1) on a form, when the button is clicked, I want it to run a program, named 'mover.exe' which is located in the SAME FOLDER that my visual basic program will run from. The directory of this folder will change. So, there are two problems I have:
1 - To make the program run the .exe program when button1 is clicked (it also must be run with administrative privileges).
2 - To make the program always look for 'mover.exe' in the folder in which it is started from.

There are tons of examples of how to access the process environment block (PEB) from C++ code but I'm wanting to do it from VB.NET and am seriously struggling.I call NtQueryInformationProcess and get a Process_Basic_Information structure back from that which has a member named PebBaseAddress and this holds a pointer to the PEB (I have verified that this member does hold a valid pointer at runtime). The problem is that when I try to read data from the address that this pointer references I just get nothing. One important thing to mention is that it works fine if I try to use it on my own process, its just when I try and read the PEB for an external process that it gives me no data. I've enabled the SeDebugPrivilege (and confirmed it is enabled for my process in Process Explorer) but this made no difference. I've also tested it on Windows XP x86 as I'm currently testing on Windows 7 x64 but XP had the exact same issue, only sometimes the XP one would just crash completely with a memory access violation and thats the other thing, I am getting fairly inconsistent results - even on the Windows 7 machine sometimes I end up with no data but other times I get memory access violation errors, and other times I get the data for my process even when I have passed in the handle of a different process..

I have a MS Access database set up, with a Period field that has either values 1, 2, 3, 4 or 5. I retrieve these values using a database connection and I would like to reference a particular control based on what period was grabbed from the database.
Here's example code, pseudo of course.
TextBox(dr(3)).Text = dr(0)
dr(3) contains the period, and dr(0) contains the content I would like to put into the text box. I have these text boxes on my form: TextBox1, TextBox2, TextBox3, TextBox4 and TextBox5.
So if dr(3) contained 2 then I would want to reference TextBox2.

sort the listbox that is being populated by data from an exteranl hard drive. The DB's on the Hard drive are contained in folders with a naming format as follows (Jan94 - Dec08)The issue is that on the HD all the folders(yrs) for Apr are listed together and then the rest listed the same way, just sorted based on 1st alpha character. The format I want to show in the list box is as follows:

Part of my project is to retrieve a string variable from an external source (google docs) and parse it. This string represents width and height. I have no problem retrieving, I just need to parse it in to two strings. The string has 4 variations.
Here are examples:
3"x4"
3"hx4"w
3hx4w
3x4
The width is always the first number and the height is always the second. Sometimes, the width and height have decimal points. Any way to parse this into two strings of the numeric values only?

We use a 3rd party engineering application that does not expose an automation model. We can 'automate' it after a fashion by using low level Win32 API calls. I can get the Process by iterating the GetProcesses method. Is there a way to attach to the app by using the NativeWindow class?

So i want to start an application with my vb.net app and it should start as a hidden process, meaning no window and nothing in the task bar, only in the task manager ofcourse.
This is what i do
Dim fov As New Process
If CheckBox2.Checked = True Then
RichTextBox1.Text = RichTextBox1.Text & vbCrLf & "* - Launching"
fov.StartInfo.FileName = ("test.exe")
[Code]...
This does not work.. I have also tried the "fov.StartInfo.CreateNoWindow = True" command which does not work either. I can live with a solution that would start the window minimized instead of totally hidden.

I don't know what this is called so I've struggled to find an answer from google but I have a vague memory of it from t'old days.I've sub-classed (* see below) about 8 framework controls, overriden some properties and added some functionality into each one.The changes I have made are identical in every case. If I make a change, I have to go through each class and apply the same change there.I was hoping there may be a keyword such as <IncludeSourcefile "common.vb> that I can put into each class.
(* note) I use the term sub-classed but I don't know if that's the correct terminology. I've also seen it used for call-backs. Is sub-classed the correct term to use?

I want my vb.net dll to get the data sent from c++ project(exe).Can any body help on in what form this void pointer can be sent via pipe. The void pointer corresponds to enums or structures. I have to get this structures/enums on the vb.net dll end. I have mentioned about using pipe. My question is as what type the pointed to data can be send over the pipe so that I can easily handle the received data at the vb.net dll end.

I have created a data source connection to an access db by using the wizard in vs2008. I have then used this as a data source for crystal reports. My user would like to put the database on a network and reference it there. Is there a way to set a new path for this data source during runtime?

When I load my solution and compile it after first starting the IDE, everything works as expected. After changing source and recompiling, I get the following compile error:
Error 11 Unable to copy file "objDebugCAMDRS.Library.dll" to "binCAMDRS.Library.dll". The process cannot access the file 'binCAMDRS.Library.dll' because it is being used by another process. CAMDRS.Library.
After closing Visual Studio 2005 and reopening the solution I can compile again successfully. This is an old solution that has been fine for a long time. I just recently changed computers and reinstalled everything.I am running win XP Pro sp2, Visual Studio 2005 sp1.

My program writes to a .txt file (and this is the ONLY program that writes to it) in a thread (with lowest priority), but every now and then it gets an error "The process cannot access the file because another process has locked a portion of the file" when it executes this code: swLog.WriteLine(sPacket).Other program reads from the file, not write to it, why do I get this error, and how can I get around it, or what shall I do when I get this error since I can't write to the file ?

I'm using Process.Start to start an external command line application and using the StartInfo.Arguments method to send parameters to the application. I imagine I'll need to use a loop... but I can't figure out exactly how yet.I need to send anywhere from 1 - an infinite number of files names to this application. Each file has to be sent one after the other. So once the first one is done, I need to loop back around and past the second one.I can probably use the Directory.GetFiles method to get all of the files, but I don't know how to assign them.

I'm trying to run the "Shell" command in a VB.NET project, to execute an external file. For example: Shell("c: empmyfile.txt").
For some reason this throwing a "file not found" exception, yet the file is there. Now I've looked around and found that others recommend using the "System.Diagnostics.Process" method, which does work, however I don't want the file to run in-process, which is what that does.
I want to run the file out of process, so that when my program ends, the executed program keeps running independently. Hence my attempt to use Shell() but it refuses to work.
Is there another way besides Shell() to run a file out of process?

How can i access a file through FileStream which is being used by a window service. Actually i am trying to access a file which is also being used by our window service. I need to read data from this file. I am using below code but also getting following error:
Code:
Dim fs1 As IO.FileStream = New IO.FileStream(psPath, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
Dim sr As IO.StreamReader = New IO.StreamReader(fs1)
sData = sr.ReadToEnd
Error: The process cannot access the file 'FILENAME' because it is being used by another process.
I tried changing FileShare.Read parameter to FileShare.None but it didn't work out. I also read below post which says that it is not possible but i think there is a way to read it like if you open a file through Firefox but still window service is accessing it.

The process cannot access the file 'C:UsersJoshuaDocumentsTest1.txt' because it is being used by another process.Now the Problem. When i step through my code, it will do as intended, e.g. clear all contents of test1.txt. when i run it at run time it throws this error. The reason for it throwing an error is the text file is reading string, int, string, and the txt file has a string including in the int part, so i'm making it so you can empty a corrupt file.
