I have created a program that saves and opens a custom filetype that I have created. In windows I have associated this program with that particular extension. What kind of handler do I need to tell the program what to do when it is started by double-clicking a file that it is associated with? As of right now, the program starts, but of course it doesn't know what to do with the file that started it, so it does nothing. I searched with no luck, sort of hard to choose keywords.
I'm coming to end of a program I've been writing for quite some time now. In this program, I use text files to store/retrieve all the data I need for the program. I've save each file with text characters, with a file extension of .fad.
The problem is, how do I make it so when someone double clicks on one of my .fad files, it launches my program and opens that file?
how can I get my own icon to appear on my .fad files?
I have a config.txt where some of the parameters are set. When I start my app, I want to read that textfile and get these values. But the thing is I want to do it during the splash screen time. Is it in the applications event.vb?
I should I do so that when a program is run, it automatically checks for conditions. If true, it will continue opening the form but if false, it opens another. What I've done is it goes directly to one form and if false it will close the form using me.hide() and loads a form using Form1.show(). Problem is, if the condition is false, both forms will open. What is the right way to do this?
I'm using this code to find all the start up programs.
If e.ColumnIndex = 1 Then Dim key As String = dgv1.Rows(e.RowIndex).Cells(0).Value.ToString If dgv1.Rows(e.RowIndex).Cells(1).EditedFormattedValue = True Then
I am trying to launch a program using System.Diagnostics.Process.Start("C:Program FilesFrets on FireFretsOnFire.exe") but the program always fails - the program generates an error log - so its obviously trying to start - ive included the log text but i doubt it will be useful.
Traceback (most recent call last): File "FretsOnFire.py", line 45, in <module> File "GameEngine.pyo", line 23, in <module>
Yet it runs fine when double clicked? why i can launch it from explorer but not from my code
I got the start function, but know i wanna resize the program i am gonna make it start
Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click System.Diagnostics.Process.Start("C:GAMENAMEgamename.exe") End Sub
How to add to that code and make it so it makes C:GAMENAMEgamename.exe start as windows size?

how I can start a program with Visual Basic Express Edition 2008? I mean do you have any code I can use as a base to start another program? If that made sense.
I'm getting a really strange error. I have a program that needs to run a thread on startup, and for some reason when I do myThread.Start() in Form1() it will crash with "program is not working" (But only on Windows Server, not on my local machine!). However, if I put the same code under button1_Start() it works no problem. What gives?
EDIT A little extra information: In my thread I have a line of code that uses invoke
And for some reason the crashing goes away after I make the thread sleep for 2 seconds before it starts executing. Am I using the right method to execute code on the app startup?
I'm typing this up only to document it and possibly save others the three days of frustration and hell I had to go through. Because this unhanded exception was damned near untrappable (it happens on Form.Show(), but since my primary form was affected, I couldn't tell at the time), it's one I know I lost a lot of hair nailing down.
I have an office application. Standard fare utility program that grew to do lots of custom tricks for my place of business. Lots of database providers to pull data from various unconnected sources and crystal reports to make fancy reports from it all.
When I make a change or addition to it, it usually is only needed by one employee, so I only deploy the new version to one computer at a time. Recently, I had to reinstall the program to the whole company. Everything was going fine, until somebody who had a Windows XP machine tried to run it. It was giving a "clr20r3" "System.InvalidOperationException" on program boot. None of my Try-Catch blocks were catching it. Any Windows XP machine I installed it on was failing, and any Vista/Win7 machine had no issues at all.
I spent the next three days trying to catch what was causing it, pulling out references, reinstalling .NET. Searching for references to this error online was futile since System.InvalidOperationException is one of those ultra-generic errors that pop up for hundreds of oddball reasons.
Finally, by happenstance, I found the cause via a single, obscure post on TechArena by a poster with only that post to his name who decided to chime in with his two cents on someone else's System.InvalidOperationException problem.
About a month ago, I replaced the program icon with a new one. I made up a nice Icon, and compiled pre-sized versions of it into a proper .ICO file from 16x16 all the way up to 256x256. I replaced the program icon with it, the links to the shortcuts in the setup program, and the icon on the main form.
THAT was the bug. Because my .ICO file had sizes larger than 64x64, Windows XP couldn't handle it as a form icon! It works fine for the program icon and for the shortcuts, but the form icons MUST be 64x64 or smaller or the program will throw System.InvalidOperationException on Form.Show(). I didn't know this was the issue since this change was over a month old and I hadn't needed to upgrade a Windows XP machine in that time. Windows Vista and 7 can handle large icon files just fine!
Solution, I made a second, WinXP compliant icon just for the main form. Problem solved. My big icon is still used for my program and shortcuts, so they look great scaling to max size in Windows Vista/7 and XP no longer crashes with a cryptic error message.
While i Minimized the program and clossing the program , next times i start the program, it also minimized. how can i prevent this problem happen!! And i want to start the program at position which start minimized. how can i do it!!!
I'm trying to open any file using Process.Start, but every time I try to open a file that isn't an executable the program crashes... This is the code I'm currently using:
vb.net Private Sub ListView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDoubleClick For Each lvi As ListViewItem In ListView1.SelectedItems Process.Start(path & "" & lvi.Text) Next End Sub
Path is a string that contains the selected folder path, and lvi is the text of the list view item (each item contains the icon and name of each file). It is working fine for .exe files, I was just wondering if it's JUST for .exe files...
But thing is I renamed this player to myplayer.mo so will it work like a normal exe or is that not duable ( I know u can do this in VB6 ) but not sure how its done in VB 2008
I have more than one file under project. Where do I configure the first/start file when debug? Example: form1.vb is load by default when debug. Now I want it to load login.vb instead.
Im simply trying to load a file on my network. The file is a database file for access.. This code opens the file on my computer. However on the four computers tested 2 of them throw an error stating that the user canceled the operation. However the user didn't do anything. The error is thrown automatically. The other two are working perfectly fine.
I have a startup form with one list view and one combo box. When combo box SelectedIndexChanged a make call a subroutine that perform read of a file. In Main_Form_Activated i give a default value in my Combo box. The problem is: The program didn't show me the main screen and after call the subroutine to load the file but without show me any screen starting to load the file and they show me the screen AFTER the load of the file.
I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.

Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?
