C# - Software (or CommandLine) That Dynamically Runs Dotnet Code?
May 4, 2012
I once heard about a software that could dynamically run dotnet instructions (C#, if I remember well) on its command line, e.g when entering 1==1, the output would be true.I don't remember the name of this soft, and sometimes one just wants to know the result of a given instruction, without having to create a new program, compiling it and run it...
I would happily take the challenge to make a soft like this on my own later, but for now on I'd just like to find this soft.Does anyone know its name, or another app which would achieve the same result? (Don't tell me PowerShell, I'm searching for something more handy.
EDIT For those who use Visual Studio and who didn't know (I just learnt about it), you can also use the Immediate Window. It even allows you to get intellisense in some cases.

I've created a form with a PictureBox on it and would like to dynamically create another PictureBox on the form while the program runs (to the left of the static one). I've written this code:
Dim temp As PictureBox
temp = New PictureBox
temp.Image = StaticPictureBox.Image
temp.Visible = True
[code]....
When I run this code I can detect that the temp PictureBox does get created. However, it is not rendered onto the form. It seems like it's there but is invisible.

I've got a vb.net 2005 form that calls a stored proc to load a combobox with eligible sales reps. There are approximately 40k sales reps available...I know that's a lot, but that's what I'm dealing with. I'm trying to figure out why it's taking this form 15 seconds to load.
Here's my code:
Want to load this in the most efficient way possible given the HUGE amount of data that my client is wanting to see.
Can you help me? :confused:

Having recently installed IIS Express I was hoping that it was going to make life easier for me, but I've run into a problem almost straight away.Consider the following which is representative of some live code:
Public Shared Function GetServiceId() As String
Dim principal As MyCustomAuthentication.Principal.MyPrincipal
principal = CType(Thread.CurrentPrincipal, MyCustomAuthentication.Principal.MyPrincipal)
[code]....
Running the code under the ASP.NET Web Server (Cassini) everything is fine and I can see that Thread.CurrentPrincipal is of type MyCustomAuthentication.Principal.MyPrincipal.Running under IIS Express this same line throws an InvalidCastException and checking the type I find it is now of System.Security.Principal.GenericPrincipal which is confusing as nothing else has changed.I can confirm that MyCustomAuthentication.Principal.MyPrincipal implements IPrincipal and remember this is Live code, it is currently deployed and working.

i wrote a piece of code to write some data to a card reader, and read back from that device, filling a form with the data (after reformat).When I step through the code while debugging (using F5, F8 for stepping forward) the form is filled correctly.However, when I run the code (Ctrl-F5), the program seems to hang for about 5 sec and then throws an exception: 'Length should be >0' When looking further during debug - it seems that the program calls 2x the Sub Frm_Read_Display().

I'm creating some buttons in Word 2007 that I want to use in my company application to make our teams life easier. The application is a server application but when it loads it goes through our internet explorer.If I could reveal the source code then I could get the ElementbyID to hook up the button to the text field in the application.When the application loads I can quickly right click on view the source code and it is written in C#.This is one of the id's i was able to grab
id="upEnvironmentHidden" value="PRODUCTION"
How can I make it possible to view the source code of this application...also the internet explorer will dissapear and then the application is launched.

I've almost completed my first VB.Net app which is a rewrite of an old vba app I wrote.The last part that I need to write is the timed events part. What I have in VBA is quite straightforward.Every 500ms the Timer event runs through, it checks if certain variables have been flagged and if so runs the relevent code? Code is nothing major, just updates a networked device.I've looked into timers in .net but it seems like there are various routes that I can go down.

Option

When I run or debug the code, it asks for the First Number and then just completes the running of the program without asking for the second number and uses some random number. The console.readline() doesn't work either, the console window just disappears.

I was wondering if there is any way to make a sub run when another bit of code has run like doing a handles event bit.The reason I want to know is that I have made a custom message box and would like to effectively create a shortcut by whereby when the string CusMsg (my chosen variable for the message box message) appears in the code and runs, it makes form3 (custom message box form) open and label 1 on that form is the writing the of the message.

When debugging my app it works fine i.e. It gets the two commandline args, through a loop, and execute as expected. However, once I publish it, the app only picks up the first argument, which is the .exe file string. Code below:
Public Sub Main()
Dim args() As String = Environment.GetCommandLineArgs()
Dim n As integer = args.Length

I have some vb.net code which should print out labels using Teklynx LabelView software (which I've had working before.)Problem is, it runs fine on Dev machine, but when I run it on the end user's PC, I don't get any error messages until it completely dies with the "Send error report to Microsoft" message.
How can I troubleshoot this???

This is the command line I want to use inside my VB.NET program. Look for the running process "mpc-hc.exe" and get the commandline of the running processwmic process where name='mpc-hc.exe' get CommandLineI want to retrieve the output from that command into a string. I know that it could be done natively in a VB.NET program and I have looked at how it was done. However, I cannot get the code to perform what it did in the commandline I have above.

I'm using VB.net to have a GUI on top of a commandline program.
[code]...
Which works and prints out all output from the commandline program. However at some point the commandline program ask for user interaction, eg: Type a number (1/2/3/4):But the commandline program stops after this. I suspect this is because it doesn't receive a valid option.Is there a way to capture when the commandline program wants user interaction and hold the reading of the stream to be able to enable the user to input something?

I have an app that allows a user to type in code that can be executed much like vba code in the office world.I currently execute this code with the Proprietary Dexterity code used with MS Dynamics - GP.However, my users need to be able to run outside the Dexterity world.The easy answer is to allow them to type in vb scripting or vb code instead of dex code.However, I can't find an easy way to dynamically execute their code within my methods.CodeCom looked like it could be the answer, but If i'm reading it right, I would have to know what libraries the user is using in their code for vb.Thus, I thought to simply limit them to vb scripting.Unfortunately, I can't find a way to execute vb scripting from within vb, (all the articles are ancient and most links fail - thus I gotta believe there is an easier way).I'm at a deadline where I developed the prototype but trying to use sql statements failed miserably when trying to execute.

I want to exit my GUI application (vb.net 4) using a commandline parameter.I should send thive! from the commandline:
myapplication.exe quit and an already running instance of the application should exit.
Now, I have a mutex detection in place so that I can only have one instance of the application running at a time. It seems that if I send a commandline, it won't work on an already running application; it will only work on one that is launching.

I've been working on a project that converts several file formats to a PDF in VB.NET/C#. The specific files are DOC, TXT, JPG, TIFF, HTML.
Actually I already have a solution for DOC/TXT to PDF using Bullzip PDF Printer by sending the files to the PDF Printer using VB.NET. However, each time it converts a file, MS Word opens and then closes once the file is sent to the printer. It really slows down the process.
As for TIFF to PDF, I haven't found a solution for it at this time.
I require SDKs or Commandline tools and not PDF convertion applications, since I need to integrate this function in my program. I prefer free or open source SDKs but commercial ones are accepted as well.

I have an application that has file extensions associated with it. The application has been deployed using ClickOnce. I have checked the associations table to confirm the entry is there and the association is to the 'ClickOnce Application Deployment Support Library'. When the application is triggered using a file with my extension, it does not pass the filename / directory in the CommandLine Arguments, instead you get the executable path of the application.
Which is under ..LocalSettingsApp"Random Strings"MyApp.exe
I have checked the Registry entry to confirm what the extension is set to open with and the application is dfshim.dll. Is there a way to overcome this, or is this just another limitation of ClickOnce deployment?

I have commandline strings that contains application paths and might contain arguments. Some examples:
1. "C:Program FilesMicrosoft Officewinword.exe" "C:some dirdocumentname.doc"2. "C:Program FilesSome Dirapp.exe" /dosomething3. C:Program FilesSome Dirsomefile.exe4. C:somedirsomefile.exe /whatever5. C:Windows
otepad.exe6. someapp.exe
I'm looking for a simple way to split the path to the application and the optional argument.Sometimes the string contains quotes around the path (1&2) and sometimes, even when the path contains spaces, the string does not contain quotes(3). And sometimes the string does not contain spaces in the path (4&5&6), but a space is used before the argument(4). And (6) is a executable without a path. I have to use the environmentvariables the find the fullpath of the executable. This string (6) can also have arguments.Is there a standard function available to do this split?
Note:I have a regex pattern to handle (1,2,4,5,6), but is doesn't work for (3), because of the spaces in the path."[ ]+(?=(?:[^""]*""[^""]*"")*(?![^""]*""))"I cannot control the strings. Some of them come from user input and some of them come from the registry.

I am developing an application that will run with a GUI when no commandline args are passed, but can also run invisibly if started from the commandline and passed necessary arguments. I have been asked to include a /version argument that will return a version number. For simplicity this version number can be stored in a variable. Without doing something like writing the version number out to a file, what is the best way for me to return this info to the caller? My app will almost always be started from a script, so the script will have to read the version number and make decisons based on the version.

we currently use our own 3rd party customer management system that is cloud-based. They offer pretty good reports; however, we need special reports and the only way to do this is to download our database though web services that the vendor offers. I have some education and experience with programming, but it has been a while. Instead of having to actively engage the webservices directly, our vendor has offered a stepping stone. They have a command line exe that interacts with the webservices and, with the use of different parameters, gets us to the point of having all the data downloaded in xml, csv, or screen printed - the only problem is that it will only do this a table at a time and there are 43 tables I need to interact with. I need to build something that can either be a console application or something that can be run automatically in the middle of the night when there is no load on the server.
Here is what I need to happen:
The command is CMSDownload.exe. It needs to login (again, there are already parameters set up to do this so I can hard code that into the script) Once logged in, the script needs to check a parameter that has been saved that signifies the last date of successful completion. (Obviously, it needs somewhere in the code to place this parameter also). As I mentioned before, each table needs to be downloaded into its own xml file individually. For instance, the following is one example of a table being downloaded in this fashion:
Generate an XML file of all of the data in the accounts table between '01/15/2009 09:13:34 AM' and 01/16/2009.CMSDownload -d somedn -u someusername -p somepassword -f c: empaccounts.xml -m xml -o all -t accounts -s 'start date' -e 'end date'
-d is a login component (credentials)
-u is a login component (username)
