View 2 RepliesI use Visual Basic.net to create a program that connects to several websites, logins, then post some data. I can't use the httpwebrequest, some java is required on those sites, so i use the webbrowser control.Now I created a form, some fields for input data and a submit button. The coding part is like this:
Code:
sub website1(vars)
'login here
'post some data
[code].....
The problem is that I can't control what happens after submit button is clicked. I need to pause or stop the process at any time. If I exit the program while processing, I can see that even if the window disappear, the program is still running!I tried to use a thread for this, but the subs only get called if I use begininvoke, or invoke on a starter thread.
I am trying to make a very simple program that connects to a MySQL database using VB.NET. My program only has one form and one label. I setup my MySQL database to have a table and one field (a VARCHAR)called "Tab1". I manually inserted the value "CLOSED" into the Tab1 field using PHPMyAdmin. I want my program to change the value of the field to OPEN/CLOSED and I also want the label text on my form to change too when it's clicked.

View 7 RepliesI was trying to make a program for a teacher that automatically determines random students that he or she can call on.I'm trying to make a program that will allow the user to add student names to a listbox. Then, when a button is pressed the program will output a random name from the list. I keep getting a lot of errors and can't seem to figure out why. Finally, I need an exit button that should close the program. I need to assign access keys, have a proper tab order, and assign default and cancel buttons for the form. Also, if you know how to implement any extra 'bells and whistles' into the program,I've tried making this program but it comes up with either a lot of errors, or it just doesn't want to debug. Was wondering if I could either get some help with the coding or the "how-to" on doing this.

I am manually adding a record to the underlying database using an OLEDBConnection/command (cloning the current record).

View 7 RepliesI'm trying to get a VB2008 multi thread application working that connects to a local server program using sockets. Server requests for this particular system can be more quickly handled by a number of connections, so I've written some code to run any number of data request threads that I choose. The problem that I'm having is that the data returned from the server is getting mixed up and is often returned to a different thread/socket than the one that requested it. Other than that, it seems to work okay. If I use just one thread, then the system works as it should. Pls. see incuded code, which is heavily edited to remove all the other fruit salad. Is there any way to set up the sockets so that data returned to the socket/thread that requested it?

Suddenly whenever I build my applications, although I get a "build succeeded" result - the executables are either not updated or updated in the "wrong" place.So for example if after succesfully building I press <F8> to step through the code I get a message saying the "source is different from when the module was built"I have no idea how to begin tracking this down - how .net determines the placement of files and so forth.

View 9 Replies"Employee Monitoring Program"
Source: Visual Studio 2008 Pro
Language: Visual Basic
I already Installed the components came with the VS2008 Installer (Sql etc)
The idea of the program:
The program will create a personal information of every employee including the userid and password that will be use to log in (user validation) .The application will monitor the login / logout and save the task of every employee.he application will save/store the daily activity task done by the employee (login/logout time,notes, and other task assign). the information will be saved in a database which can be access by the application in every PC within the network (LAN).The application will be installed in different PC within a network(LAN). The number of PC is not yet confirmed (5-10 PCs)
The application will be used concurrently within the network.The database will be updated after the employee save his/her task.
I plan to have ONE application only, to make it simple no server type installation and client type installation needed. Just one installation type only, the functionality/privilege will depend on the login information validation.
There will be 3 account types, Manager Account (Administrator),Regular Account (Normal Employee) and Guest account.
1. How to create an application which the database will be on the other PC within the network (LAN) ?
2. How to do it during run time/design time ( the database will be on the other pc)?
3. Can I have a guide or walk through on how to do this project?
