I just switched to Win7 Ultimate edition 64bit and now the beep functionality via internal speaker (system speaker on motherboard) does not work anymore.The reason is described here (basically M$ trying to clean up their code):url...I used "Console.Beep(a,b)" to notify me that a process has ended.Any ideas how to send some kind of acoustic signal through the internal speaker (any loud noise would do for my purposes).
View 14 RepliesDepending on what component is handling the print for you, some of them are not 64 bit ready (i.e. 32 bit only). To use them you must compile your application as 32 bit only. It will then run on the WOW platform that Win7 supplies.
You change this option on the PropertiesCompile screen. Press Advanced Compile Options and review Target CPU:
Does the NDde class work on 64 bit platforms?
I have used it successfully on 32 bit Win XP VB2008 Express application, but I am having trouble in 64bit Win7 environment.
Specifically the .Connect method is throwing an exception {"The client failed to connect. Make sure the server application is running and that it supports the specified service name and topic name pair."} NDde.DdeException
I'm using VB.net 2010 express, where can I find the compiler option for 64bit? or, it will compile for 32bit only? or, it should work for both 32 and 64 bit in most case?I'm using a 64bit component in the program, vb express reports error when I compile it, but if I use the 32bit compnent, then it is ok.does it mean express 2010 automatically compile to 32bit? or somewhere I should set the win7 64bit (which is what i'm using).just start using win7 64bit & vb express 2010, got confused

View 1 RepliesI have written a Forms application that analyzes a lot of (~1400) 8-bit jpg images from automated lab-equipment. I am in the process of migrating from WinXP to Win7 and to my surprise I noticed that analysis was 5 times slower under win7 compared to win XP (!?!?!). I investigated further and found that the loading of the jpg images was the step that was takning longer! The simple code demonstrates the problem: On XP i get 70 images per second, but only 12 images per second under win7. Has anyone else noticed this performance drop, and can something be done to improve it?

I'm updating a program that was written in an older version of VB (by someone else) and I can't figure out to how replicate this data entry line in my Form.
Each textbox can be changed and there is a nice scroll bar at the bottom to move left and right as you enter each datapoint.
I tried using multiple tabs within a Panel and setting the Appearance to FlatButtons, but the text area under each tab gets covered when you select another tab.
I have looked everywhere on this but do not know anyone who have accomplished it so far that is how to read values from a grib (gridded binary) file. Below is a link for Environment Canada where they store the forecast values in grib format. These file can be opened using tools like wget but is nowhere close in reading the data values from the file itself.url...
View 2 RepliesI currently have a program that I made which opens other apps packaged with an installer. I have set the installer to install everything to the Program Files folder. However, not all computers have a C: hard drive. I have a way in which they can enter their drive letter in one form then in the next form it remembers the drive and will take them to the program. The problem is my program stores the drive letter in an xml file. On the startup of the program it looks in the xml file to find the drive letter, if there is no drive letter the form opens then lets the user set his drive letter. The xml file is stored in the folder "Math Wizard" in the Program Files folder. But if not all

I'm working on modifying this example:
Using advWorksContext As New AdventureWorksEntities
' Call the constructor that takes a command string and ObjectContext.
Dim productQuery1 As New ObjectQuery(Of Product)("Product", advWorksContext)
[code]....
An ObjectQuery can be enumberated only once. (Subsequent attempts at enumeration throw an exception.) The enumberation takes place in the for each statement. The problem is that if the query is empty attempting a For Each will throw an exception. But if I check for a count:If productQuery1.Count > 0 Then . . .
That eats up my one chance at enumeration. I could nest the For Each in a try/catch block and throw away the empty query exceptions, but that's ugly.

View 7 RepliesThe sample below does what I want it to do and that is once I've filled the maskedtextbox and press enter it goes and does stuff. However, because the maskedtextbox is full I get an annoying 'beep'. So I figured I'd just use the tab key, I changed theChrW(Keys.Return) to ChrW(Keys.Tab) but it doesn't fall through, it just changes focus to the next maskedtextbox that I have. Is there a way to lose the beep? Or how do I get the tab key to fall through?
