I have a program that opens the command prompt and sends commands. I need to leave the first CMD open, open ANOTHER cmd and send more commands to the second one.
Then I do some processing and can close them both. How can I open more than one, and how do I refer to the first or second one?

View 1 RepliesI made a small VB.NET application which includes a Crystal Report. Running the Crystal Report on the machine I made it works perfectly. When I run the application on my laptop, the Crystal Report always prompts me for a login even though the database has no login set to it. I have tried passing in "Admin" and "" with code, but no luck. I'm working with an Access database, this is the code I have to load my Crystal Report:
If frmReport Is Nothing OrElse frmReport.IsDisposed Then
frmReport = New frmReport
End If
frmReport.CrystalReportViewer1.ReportSource = "../../Reports/Klantenbeheer.rpt"
frmReport.MdiParent = Me
frmReport.Show()
I did look at Prevent login of ODBC Text driver in Crystal Report for Visual Studio 2010 but I'm not sure if it applies to my situation? I also tried setting the rpt's datasource to the datasource I work with in the application and then assigning that to the ReportSource, but no luck either.

View 6 RepliesI'm writing the following bits of code for a SaveFile Dialog box in Visual Basic 2010.NET. The code works well as the XLSX file is created and opens in Microsoft Excel. However, the problem that I am having is that if the program overwrites a file, the user is getting two prompts. One prompt is from the program's own SaveFile dialog confirming the choice. The other is from Microsoft Excel asking you the same. It's as if the program is running in the background. Does anyone know how I can write this code to save the file as an Excel file? [Code]
View 1 RepliesI'm trying to create a program that does the following:Executes the following command line string (wmic /node:computername bios get serialnumber)Prompts user for the "node" entry Displays the resulting serial number in a dialog box I'm a bit of a noob at this (I haven't coded anything in VB since early 2000s) so I'm at a bit of a loss where to start. I plan on including some functions to submit the node entry and the resulting serial number to a database in the future for archiving as well.
View 4 RepliesWe have a issue with laptops for the current client in which IE continually shows prompts to users about working offline. The laptops are on a flaky wireless connection (Personally I would much rather fix this but they would much rather just fix this issue, apparently this works better money wise. I have my doubts).
Anyway the issue I'm facing is removing this box from opening at all.. Now there are two ways I can think of doing this. A possible Hook if it is available to catch it before it comes out and stop it. Or the less nice way is to when the box comes up to automatically hit the "try again" option using a sendkeys push.
I have to create an application that prompts the user to enter today's sales for five stores. The program should then display a simple bar graph comparing each store's sales. Create each bar in the bar graph by displaying a row of asterisks (*) in a list box. Each asterisk in a bar represents $100 in sales. I have to make two different versions of this program. One using a "do while ... loop" and the other using a "for ... next loop". Could someone give me a hint on how to do this. I the "do while ... loop" version and I have had some problems, especially with converting the numbers to asterisks.

this is my first vb. and i have assignment and i have been trying for hours but i couldn't do it right I have to create an application that prompts the user to enter today's sales for five stores. Create a loop to prompt for an amount for the first store using an inputbox and do not exit until you have good data. The inputs cannot be negative or greater than 5000, but may contain decimal values. The program should then display a simple bar graph corresponding to the amount of sales using a row of asterisks (*) in a listbox. Each asterisk represents $100 in sales. Display the total of all the stores by looping this process for each store.

I wish to communicate over usb in vb.net i realize i might need to use openfile windows api or createfile windows api but im doing a generic mouse driver which should be miles simpler to do since microsoft and usb.org already have the report descriptors available so all i want to do is just send data to the device directly using my program.

I'm working on a little app which needs to recieve information from a script on a web server. I tried to have the vb.net app pole a php web page for a command every half of a second. This worked but, the app is streaming video and every time the app needs to pole the webpage the video stutter stops. I tried setting the pole timer to 5 seconds and still every 5 seconds the video stutters. I thought that maybe sockets would be the answer, so I looked for examples of vb.net socket servers and php socket clients. I tried implementing a solution but the php cannot seem to connect to the vb.net server. I googled around and saw that maybe php cannot communicate with a vb.net application.

View 2 RepliesI have a library that interacts with our phone system, ie, Hey phone, call this number for me. This library is used in one of our in house products.
