I have a sub that I just discovered does not work for my windows 7 users but works fine for my windows XP users. This is basically a sub for a ping monitor to ping devices on a timer. What happens is that when the windows 7 user tries to ping, it always reports "down" on a windows 7 whether actually up or down. But, windows xp will report correctly with "up". 3 different windows 7 boxes, users say it worked before. Can't quite debug correctly as i'm on xp myself and it works just fine. Also, I haven't changed anything in the code in quite awhile and this is a recent bug that just started.

Within a VB.net program I used IO.File.GetCreationTime to read the file system's creation time of a file. I was irritated, because the returned value didn't match with the time displayed in the explorer. On another machine the time was displayed correctly.

ive decided to try out win7 since its finally a bit more debugged, ive backed up very carefully all my projects, however there semms to be a problem with the one i was working on, this first chance exception error has been avoided and not even mentioned in winxp however in win7 it not only mentions it but makes the application crash, This is what its nagging me about, i dont get it isnt windows7 the same when it comes to mydocs? Was not possible to locate part of the path: C:UsersEugenDocumentsIOrganizeSettingsCalendarConfig
Sorry i had to translate it, its in portuguese language, yeah i know... if i could i wouldve changed it but win7pro doesnt gimme that option, anyways back to the topic:
A first chance exception of type 'System.IO.DirectoryNotFoundException' occurred in mscorlib.dll
This is the code i came up with:
If My.Computer.FileSystem.DirectoryExists(My.Computer.FileSystem.SpecialDirectories.MyDocuments & "/IOrganizeSettings" & "/CalendarConfig/") = False Then
My.Computer.FileSystem.CreateDirectory(My.Computer.FileSystem.SpecialDirectories.MyDocuments & "/IOrganizeSettings" & "/CalendarConfig/")
End If

I have a simple datagridview that I fill from a mysql database using the latest mysql connector.net.I configured my columns in the datagridview collection and the data displays fine.I don't want the user to edit data directly in the grid so my datagridview is not readonly but all my columns are except the checkbox one. If I set the datagridview readonly I can't check my checkboxes.I added a checkbox column to be able to delete multiple rows easily but I can't uncheck a checkbox.
Let's say I have 3 rows in my datagridview I check line 1 checkbox- I check line 2 checkbox- I uncheck line 1 checkbox- I check line 3 checkbox As soon as I check line 3 checkbox, line 1 checkbox becomes checked "automagically"

I have a VB 2008 program that has a number of forms. When I run the compiled program on a different computer, the form appears different. The relative position of various controls on the form are different. Its as if the controls have been repositioned. Resizing the form does not correct the problem. The only difference between the two machines is the size and resolution of the screens.

I have an application that will not load unless my local SQL Server is running on an Vista Home Premium machine. This started after a .Net 1 to .Net 4 conversion. I am using a sub main sub that is not being called (msgbox is not fired when entering the app), however, I see the app through taskmgr with increasing memory usage, but then the app is removed from the list. By design, if the program cannot locate a SQL Server a form pops up with a connection box to locate the SQL Server for the app. How it determines if it has a valid connection is the program looks for a connection string in the registry, then attempts to connect to it, however, none of this code executes because of the failure to enter into the sub main.The two machines I have tried the 32 bit app on

View 13 RepliesI have a program that looks for a file named 'license.dat' upon startup. The program first checks the directory it's in, and if the license file isn't there, it prompts the user to select the license file with a file browser dialog. I have tested this code and confirmed it working in a number of different OS environments.Recently, I received reports from two users (one in Germany and one in Italy) that the program can't find the license on their computers, even though it is present in the program's directory and they manually selected it with the file browser dialog. The only commonality I'm seeing here is a lack of English OS, but beyond that I'm stumped.This is the code I'm using:
If System.IO.File.Exists(System.AppDomain.CurrentDomain.BaseDirectory + "license.dat") = False Then

I am using the following Recursive Directory Copy code, and am having a strange issue. I am using this to copy and directory and all subdirectories and files to removable media (flash drive). Everything copies perfectly fine except for 1 file. this occurs on the same file every time and sometimes the file copies successfully, but other times it does not.The problem file is a 7-zip archive with a .7z file extension.When it does not successfully copy, the file is only 8 bytes on the flash drive.[code]
View 5 RepliesI am primarily a C# developer; however, I am currently working on a project for a client who preferred VB.net. I have managed to switch over fairly well, with one frustrating exception. When editing a C# file in Visual Studio pressing enter will select an item out of the IntelliSense window and keep the cursor at the end of the selected statement.
However, when editing a VB file, pressing enter selects the item out the IntelliSense popup AND moves the cursor to the next line. I realize that this is a small thing, but it drives me crazy, because it makes it really hard to switch between C# and VB projects.
I have searched for everything I can think of in Google and found nothing. Does anyone know of a way to change the IntelliSense selection behavior?

View 8 RepliesI am trying to create a button behavior such that when you click the button it fires the click event as normal & runs the code under it. But if you click & hold the button for 1 second then it jumps to a different sub & runs some other code. I got my button working that way for the most part, using a timer & the mouse down & mouse up events. The only issue I have is that after the timer fires after 1 second & I execute my alternate code, the normal button click event still fires when I release the mouse button & runs that code. How can I cancel the normal click event so that only the alternate code runs when I click,

I have an app developed in VB that works fine on Vista machines but fails on Win7. The offending line of code merely references a variable stored in a module. Evidentally, something is quite different on Win7. How to I find and fix this behavior?

It seems like this would be a very easy thing to accomplish, but, from what I can tell, it's most definitely not. My OS is Windows 7. All I need to do is get the current volume/audio level - the master volume. When you click the little speaker icon in the task bar and change the volume - I need that number. All I need to do is get the current volume and assign it to a label. So if the volume is at 74 when the application starts, I need my label to display 74. I've been searching for days now for a way to do this and I'm starting to get frustrated. I've looked everywhere. I've tried 3 different classes, at least a dozen different codes, assorted imported dll's- none of it even came close to what I need. From what I can tell, the current methods are all designed for windows xp. I need a way to do it in windows 7.
View 7 RepliesOk I have a project which has a MDI parent. Inside the parent I have multiple isntances of a form load(frmLine1t5). When my program loads it will load a different form(frmSelect) and if I manually load a different form(frmRetests) I can put frmSelect on top of frmRetests and bring one another to the front if it's clicked on(without using the bringtofront method)However as soon as I load a single instance of frmLine1t5 I immediately can no longer bring ANY form loaded into the MDI parent(before or after frmLine1t5 has loaded) to the front. I can only bring them to print IF I use .bringtofront method
