I'm writing a program to set the sale prices in an sql database based on criteria entered by the user. The application that came with the database crashes when you try to update over 1,000 sale prices at once. The other users also loose connection to the database due to a timeout error...
How can I make my new sale program pause after a certain number of updates as to not bog down the SQL server
I am trying to make a start and pause button (and hence continue) to start, pause, and continue my program. The start button works but the pause button does not. Can someone look at my code and see what the pause button needs to do to pause the program? I am using VB 2005. Here is my code.

I am starting off in the .NET world and wanted to know what a great beginner book would be that would explain how to use asp.net, vb and SQL.
I hear "Learning Visual Basic" is a good series but wanted to see if there were anymore out there.
I am really interested in learning VB .net, but I don't really know where to start. Could anyone recommend a good book or website to start learning.

View 3 RepliesMy problem is that I have a textbox that is filled with a line of data from an attached barcode scanner. I want to make it so when something is scanned into this box, another function is triggered (it clears the textbox and commits the data to a CSV file, so the user can scan another barcode). I was using a .TextChanged function so that when the text was changed in this textbox, it would commit it then, however the problem with this approach is that if the serial number is 77G8DS, then it will commit 7,7,G,8,D and S individually, instead of an entire string.
View 1 RepliesI am a EE graduate from about a year and a half ago working in the semiconductor industry as a hardware/test engineer. I wan't to learn VB to do lab level data test and acquisition. I am learning this in my free time at work and home, and I would be using VB to talk with different electronic equipment through GBIP to source, measure, and record data. Anyone have any good ideas of a good book for such applications?? I know there are a ton of books and courses out there, but 99.9% of that information is not going to be needed for my industry application. I also took a few C classes in college, and I have some experience with labview so I am not a total noob to programming. So if anyone has a good book, or refferences that would be really appreciated.Also what version of VB would you recomend me learning?
View 4 Replies1) Why the pause button and also the pause command does not exist in VB 2010 Express?
2) I have some solutions under 2010. In 2 or 3, while debugging, I can change instructions without restarting the application. In others, I cannot change anything (Is like readonly), Looking in 'My Applications', Tab 'Debug', Option 'Configuration' I can choose several Options. In the applications I can debug, the default is 'Active (Debug)'; in the others is 'Active (Release)'. If I change the options, the word 'Active' remains attached to the original option.

View 3 RepliesThe problem that I'm encountering right now is that I can't seem to get my program to wait for a couple seconds for another application to load before it starts to check if it's open. Here's what I've got (feel free to tell me its a terrible way of writing!):

So if I don't have the sleep function then oasicer hasn't loaded and it says it's finished straight away, but if I call a 5s sleep then it crashes, and not for just 5 sec. Is there a replacement for this line? Something that would just delay going to the while loop?
I am not sure how to make my program pause in the middle of execution, waiting for a certain period of time to pass BEFORE the next lines execute. I have already used System.Threading.Thread.Sleep(int) but this pauses the waits but still executes the subsequent code. If I were to:Private Sub Hello()System.Threading.Thread.Sleep(int)MessageBox.Show("Hello")End Sub* Time in milliseconds.This would NOT stop the execution of the MessageBox for int seconds, the program continues to run???How would I pause the code execution where I want, and for the time I want?

This is transmitted to program over netstream.I want the code to pause though while waiting for an answer as different routines are run dependent on the answer.

I have a program that checks the system time every 250milliseconds and I need to skip checking it three times the first time it comes back with ":00" seconds from the system clock.

View 2 RepliesOut of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)

Anyone know of any cheaper options that will do a good job? I tried a couple of cheaper RTF to PDF convertors, saving the Word doc as RTF via the app but the PDF they output lost formatting on Word tabs, table of contents, page numbers, etc. Not good enough.
Otherwise, I will have to tell the app users they will need to convert the Word doc to PDF themselves (unless they have Word 2007 and pdf add-in which I can probably offer as an option).
