Error-:-The Parameter Is Incorrect - Boolean StartWithCreateProcess(System.Diagnostics.ProcessStartInfo)?
Jun 30, 2009
I have a service that runs under local system that I need to have execute an external .exe using alternate credentials. Using the code I have posted here, I get the error "Error-:-The parameter is incorrect" and the target site is "Boolean tartWithCreateProcess(System.Diagnostics.ProcessStartInfo)"Here is the code:
Try
Dim AuditProcess As New Process
Dim p As System.Security.SecureString = New System.Security.SecureString
I am getting following error whenever I want to use IIf function inside entity framework query.
LINQ to Entities does not recognize the method 'System.Object IIf(Boolean, System.Object, System.Object)' method, and this method cannot be translated into a store expression.

In this screen I want to let the user decide which elements are on shown on a label. When I hit the update button (BDUpdate_Click; see below), it first checks whether the Barcode sample text is empty. Afterwards I want to invole the refresh of the label preview. The strange thing is that the first time it works fine, but when I alter the sample text and hit the button again, I get the Error "System.ArgumentException was unhandled. Parameter is not valid." The error points to the DrawSting function in the LabelPreview_Paint Sub
Dim BarcodeLabelUpdate As Boolean Private Sub BDUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BDUpdate.Click If BDBarcodeSample.Text = "" Then MsgBox("Please enter a sample text", MsgBoxStyle.Information Or MsgBoxStyle.OkOnly, ProgramTitle)
The parameter to a sub is being passed a value like 501/500, of coarse this value should be converted to 1.002. Unfortunately, the actual value being passed to the parameter is 1.0.
I am fairly new to VB.NET (but have vast professional experience with several other languages) and am completely new to these forums (so please don't burn me if I posted in the wrong place). I have run into a rather odd quirk with System.Diagnostics.Process.GetProcesses. I have a sample application (source posted below) that checks all running processes every second for changes (created and destroyed) and tells the user what has changed, if anything, in the last second. The sample runs for anywhere between 29-72 seconds before issuing an array out of bounds error. It appears that the Windows system processes, SearchProtocolHost.exe and SearchFilterHost.exe explicitly, disappear from the list causing my application to throw the aforementioned exception. Specifically the exception I am receiving is as follows:
Unhandled Exception: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.I have noted in comments where the exception is thrown in the code below. If any of you would be willing to try this sample on your PC's or could suggest potential issues with my sample that could cause this problem
My sample code: Imports System Imports System.Diagnostics
When I use System.Diagnostics.PerformanceCounterCategory.GetInstanceNames call, I always get 0 instances returned the first time. If I actually query for a counter value first (using perfmon) and then call GetInstanceNames, it works fine. Can someone provide some insight? Do I need to get a counter value first (in code) and then use the GetInstanceNames?
I am tring to build network toolkit for my very computer illiterate techs. What I am trying to accomplish is to embed a command prompt of sorts in a form. I have been sucessful to a point. Here are my main two problems.
1: I cannot read line by line as the output of the process is generated. Rrather I have to wait untill its complete, this is ok for "IPConfig and Maybe "Ping". But for longer diag tests this would take too long and it would look like the app has crashed. So I need to figure out how to redirect the output of the process to my text control.
2: I would like to have the ability to redirect keyboard input to the process. For telnet as an example. I would capture all keyboard commands while my text control has focus and send them to the process and with the problem solved I should be able to establish 2-way IO with the process. Is there a way to do this or am I barking up the wrong tree.
I'm getting the following exception when I try to run up my Winforms app and haven't been able to find a solution to it:
System.ArgumentNullException was unhandled Message=Value cannot be null. Parameter name: activationContext
[code]....
I've added a handler for the "unhandled error" event in the applicationevents class but it never reaches that stage and there is no source code running that I can break into and diagnose.
The application was fine until I added a user control (nothing fancy, just a standard windows user control) and then dragged it onto a form in the app (user control and form were in the same application). The application builds and compiles without any errors or warnings but when I attempt to run it up I get the above error straight away.
Does anyone have any idea what it could be or even how I can go about investigating it? I'm a bit stumped on this one as I'm not sure how to investigate it. I removed the user control from the form and then I removed the user control from the application entirely but the error hasn't gone away. In all honesty the addition of the user control might be a red herring but the problem manifested straight after adding it.
So I have this weird issue where I set a SqlParameter.DbType field = to a SqlDbType.Decimal, but instead it sets it to a SqlDbType.DateTime. I'm going to include 2 screen shots from the debugger one line after the set statement. As you can see when I hover over (just after the execution of that line), it set the param.DbType to the wrong value. I can only assume that the param.DbType has code that incorrectly changing the type. How can param.DbType become a SqlDbType.DateTime when the varable I'm setting it to is a SqlDbType.Decimal? I'm targeting the .Net Framework 3.5.
Dim ItemProcess() As Process = Process.GetProcessesByName("vlc") If Not ItemProcess Is Nothing Then For Each SubProcess As Process In ItemProcess[code]....
Now I have created two sub in the first sub I started a process using process.start(preview.mp3)in the second sub I killed this process using the above code but instead of passing the mp3 file I am using the vlc.exe which is actually processing the fileFor this I have to manually check the task manager and get the process name.So my point is ,is there any way i can write a code that automatically the corresponding exe file that is using it.
I'm having a problem. I have researched this for over a week and have not found what I need. I find a lot of great suggestions but none of them work for me.My code and program works 100% if you put a valid program, process or file name in the box but if you don't, it crashes. Also if the program is not registered or in a known path it will crash.
I've tried My.Computer.FileSystem.FileExists(txtProcessName.Text) and System.IO.File.Exists(txtProcessName.Text)
But every variation I try thinks that none of the files exist.I don't want to hard code any of the paths or file names because I want this to be dynamic. I also want it to be a one file program. I know eventually I will need to get into multiple files but I like basing all my programs on a file that can be copied and pasted to any computer and ran without problems.
NOTE: This is a multi-function program. Not only does it start programs but it also terminates them, looks the process up on the web to see if it's spyware, adware or a valid program and it also is a Task manager.
I have an windows application from where i start another EXE by using the system.diagnostics.process.
I do as follows: private myExe as System.Diagnostics.Process myExe = New System.Diagnostics.Process() myExe.StartInfo.WorkingDirectory = "...my path ..." myExe.StartInfo.FileName = "...my exe..." myExe.Start()
I'm using System.Diagnostics.Process.Start to open a file using a string stored in a SQL datatable. It works absolutely fine as long as there is an application on the local machine associated with the file type. If there isn't an association, what happens is the "Save as" dialog box pops up. What I'd like to happen is to just bring up a message box or some other prompt that tells the user what the problem is, and to contact the helpdesk. Some users will be confused if they see a "Save as" dialog box, I think.
I am having problem trying to use Imports System.Diagnostics.ProcessThread to closed multiple WORD.exe session using Vb.Net. My sample code below managed to close just one session instead of all the sessions with WORD.EXE. [Code]
The programs runs fine for about 10 seconds but then I get this error message: ArgumentException was unhandled. Message: The parameter is incorrect. Here's my
Trying to integrate the google closure compiler in a batch job of mine and having difficulty getting it to work.Using command prompt I can enter the following command and get my scripts compiled. (The command is a self explanatory example)
This may be more of an OOP concept question, but here's what I'd like to do.I have an application that outputs debug information using System.Diagnostics.Trace.WriteLine so it can be viewed with DebugView.I'd like to override/extend (not sure of the proper terminology) this method to log the text to a file instead, or maybe in addition to the Trace output. This would allow me to write a new WriteLine method for my app, and I could leave all my other System.Diagnostics.Trace.WriteLine statements unchanged throughout the rest of the application.?
I have a read only file and I am using System.Diagnostics.Process to open the file.If a user tries to save the file the "Save As" dialog box opens because the file is read only. The "Save As" dialog box brings them to the directory from where the file was opened from.
I have a checkbox named chkFactureren.When I want to save the value of that checkbox to my ms access 2003 DB I get the error: oledbexception was unhandled by user code - data type mismatch in criteria expression
I recently discovered that the standard System.Boolean value is actually 32 bits - this seems pretty "far out there" since it's only ever going to be 1 or 0 - I found this information in somebody's blog which contained 3rd-party documentation on the System.Collections.BitArray. According to this blog, the individual Boolean is 32 bits while the individual index entry in a BitArray is actually just 1 bit - official documentation here at
MSDN indicates that in reality, the BitArray is just an array of Boolean Values (which would be the same size as any other boolean) that provides methods and functions useful in deconstructing System.Byte values into the BitArray and reconstructing the BitArray back into a System.Byte (same with System.Byte()).
I'd rather not go through a lot of code to restructure Boolean Arrays into BitArrays unless there's going to be some genuine memory-use improvement (which I'd expect to see if I converted large Boolean arrays - at 32 bits per index - into large BitArrays at 1 bit per index). I'm also interested to know if the Boolean is actually a 32 bit monstrosity.

After I ran it, I had a file a.txt in my debug folder but the size is 0 bytes (and when i open it is empty of course) Shouldn't the output had "asd" in it ?
I have an windows application (created using visual studio 2005) and it also is using an autocad .api. The user runs Autocad and the user enters various commands that will open forms. One of these forms, contains Windows.Forms.LinkLabels with paths to the autocad drawing files they've attatched (.dwg). When they click on the link, I need the file to open in the existing Autocad they already have open; however, the problem is that it's opening a new instance of Autocad and placing the file into it. How can I make it so it opens in the existing Autocad program already open? [Code]
it says "The type initializer for 'System.Transactions.Diagnostics.DiagnosticTrace' threw an exception."

Here is my problem: I developed one application in VB.Net in VS 2008 Express Edition on MS Vista. I published the application and created the installation setup. Now when I install this application on any Vista machine, it runs without any problems, but if I install it on an XP machine, the installation is clean, but when I launch the application, it ends abruptly without any warnings/error just after the splash screen.
Then to investigate further what I did was that I copied the source project from my VS 2008 Express Edition on Vista to an XP machine having full (VS 2008 Team System) version , and when I try to compile it there (XP/VS2008 Full), I get one error in one of the forms resx file. Incidently this is the same form that gets loaded after the splash screen. So I see there is some correlation between my application ending just after the splash screen and failing to compile the main form of the application. The error that I get reads like: "Invalid resx file. The parameter is incorrect Line 1374, position 5."
