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?
View 17 Repliesi have to write a program for my VB class that consists of a resistance checker program. I've searched like a madman to help me through this and I have found nothing >. The program consists of 2 combo boxes, the first one is the nominal resistance drop down list of the numbers :100, 150, 220, 330, 470, 680, 820 and 1000. The second list is of the tolerance numbers; +/- 0.4%, +/-0.6% and +/-0.8%. Now what i want to do is select a number from the first combo box and select the tolerance level of the second combo box and i input the resistor of said value into the text box. when i click the check resistor button it should display a message saying if the resistor is in or out of tolerance. For now I have the form all laid out and the values inputted into both combo boxes and i can go to run the program i am able to select said values. Now my problem is trying to get the right code so that i can check the resistors value.
View 2 RepliesI need to create a a palindrome checker program. Now I know how to check a simple palindrome by using the reverse method however I am unsure if the palindrome had special characters or spaces. My question is what is the code for removing spaces and special characters from a string using loops and if statements. Also we cannot use arrays.
View 9 RepliesI'm just messing around coding a ID Checker that checks registry value. if it does not equal to the string, then the program will close as so:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim check As String
check = "XXXXXXXXXXXXXXXXXX"[code]....
Now what im trying to do is, where the 'check' is, i want to add more than one UniqueID so that other users can use the app. Lets say a user with a UniqueID of YYYYYYYYYYYYY purchased my app and recieves updates.

View 10 RepliesI 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 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.

View 2 RepliesI'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
Invoke(new Action(() => richTextBox1.AppendText(string.Format("Updating {0}..
", DateTime.Now))));
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.
I know that to start a program at startup, we should add this subkey
"C:Program Files<myprogram's path><nameoftheprog>.exe"
to
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun
Alright!
But the problem is when my program has to delete a certain file in C:/ at startup, it just can't because it's not ran as administrator!
