VS 2010 Program Already Has Written To The "file"?
Dec 2, 2009
I am making a program thats writing to a file. Another program is also writing to the file. Its a txt file. My program adds some text to it.When i click a button in my program, i first want it to check if i was the "last" program who wrote to that file. If i was, then it should not write. If i wasn't, then it should write to it.
I don't know a good method for this, but i know 1 method:after the program has written to the file, it gets the size of the file and saves it. Then next time it gonna write, it checks the size of the file and compared to the saved one. If its the same, it was my program that wrote to it last.
I know pretty much how to save information into a text file from runtime VB2005. However, I wish to be able to write the information into any kind of form of file that cannot be simply opened and read by anyone (such as text file can be). Is there anyway that VB2005 can do this?
I am a sys admin for a company and our programmer left several months ago. a program they wrote is now failing and i am struggling to work out why. the program basically pulls data from a csv file into a readable form, written in visual basic. the application works on a couple of machines but not on a couple of others. i have matched up .Net framework versions, MS Primary Interop Assembly versions, still no joy. As the app works on some pc's i am wondering what other differences could cause this?
The error output is:
see the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.
Exception Text
CODE:
JIT Debugging
To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.
For example:
CODE:
When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

I just want to know whether I can use "Reflector" to disassemble a Program written in DOS and go through all the Codes of that program to learn how that program was made? If the "Reflector" is not the one for DOS Program, could you recommend a Free Disassemler for DOS Program?
I have a program written in VB 2005, the computer used to write the code was running in Windows XP and 32 bit Pentium D. Now, my boss want to buy a new computer to run the program, and he wants the one that comes with Windows 7, 64 bit. Can my program run in the new computer without any problem? Or, is there anything that I need to change for it to run there?

VS 2008 VB/I've implemented an interface to a .com program written in c++. I'm trying to access a data structure array(uNewValues) of type PLCCOMMLib.ANALOG_CONTIN. uNewValues should be a datastructure array of several elements (iSigIDCount). My problem is I only get the first array element of the datastructure.I've tried several methods and looked into marshalling but don't understand how to implement marshalling if that is the correct option.
Code below:
Public Sub AnalogContinUpdate(ByVal iSigIDCount As Integer, ByRef puTimeDateStampGMT As PLCCOMMLib._FILETIME, ByRef uNewValues As PLCCOMMLib.ANALOG_CONTIN)

After upgrading code to VS2010, the error "MSB3134: The permission set requested by the application exceeded the permissions allowed by the Internet or Intranet zones.

I am parsing a web page with the HTML agility pack in vb.net and it works great most of the time, but I have come across a site I need help with.
When I go to grab the web page with my http object (I am using chilkat http and it does not have a javascript engine) I get back the page which is poorly written with document.writes for basically the entire page.
I do not want to use the browser control to first render the page.
Do you know of anything that will allow me to parse this page easily with xpath... does xpath work with javascript? Is there a way for me to remove the javascript with the agility pack?

I've been working on a program that generates a batch file, then when you press a button, it executes that batch file. There are multiple batch files attached to each item in the list box.
[code]...
The only thing that it does when I press the button, is starts the batch file, then goes to function searchtitle, which executes the batch file again when it finds out it didn't work properly.The button text doesn't change, none of the items are being added to my first list box, and I can't do anything to the window after pressing the button. It constantly opens the batch file every 5 seconds or so.
I need to add quotes to a line that is being written to a vbs file WriteVBS("filesys.CopyFile " & OldNFile & "" & My.Computer.FileSystem.GetName(nfile) & "," & NotesFile & "," & "True")Old Nfile is a variable defined: Dim OldNFile As String = ("\" & OldPCTxtBx.Text & "" & NotesSource.Replace(":", "$"))NotesFiles is defined as
Dim NotesFile As String = (NotesTgt) & "" & My.Computer.FileSystem.GetName(nfile) I need to add quotes before and after the OldNfile Variable and the NotesFile variable I dont want to change the variable just the WriteVBS line not sure how to do it since intellisense does not suggest a better way
Can anyone think how to read how many lines will be written to a txt file via streamwriter?I know i can do a count and increment on each writeline but maybe someone knows how to countlines from streamwriter?
I'm currently using this method in calling batch files in vb.net:
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click System.Diagnostics.Process.Start("F:ipconfigflushdns.bat") End Sub
Is it possible to incorporate the code written in the batch file so that I won't have to call it like the one above?
