Maybe... I'll explain my assumptions because I am not 100% sure what you mean.
* You have a variable called Packagea which has a value of 99.00.
* You have a variable called txtpackagea which is a reference to the TextBox control
* You need to convert the text in the TextBox to a number in order to perform the calculation.
Try this:
Dim quantity As Integer
Try
quantity = Convert.ToInt32(txtpackagea.Text)
Catch ex As Exception
MessageBox.Show("The quantity entered for Package A is not a number")
End Try
Does this help?

Anyone here know if it would be possible to override the mouse click event when clicking on a POINT on a graph?
Basically, what I'm trying to do is, if the user clicks on a POINT on a graph, it will prompt him to enter comments on that particular point.
At the moment, if you double click on the graph, it will automatically open the edit chart dialog.
Anyways, if anyone can share some insight on the problem at hand, let me know.
Thanks,
Jon

You'd have to write code to map the mouse click onto the image of the chart and then determine if the mouse click actually hit the POINT on the graph. But, that would require your code knowing exactly where each point was in the chart image. As far as I can tell, there is no way of determining that...

You should use Install Shield to create package. Its very good and supply functions to create key option
Good luck

Hi,
I'm trying to create a little service that connect to a SQL database.
I'm using USER ID and password for authentication and everytime I try to open the connection I receive the following error :

cObjConn.Open()<br />
<br />
Catch se As System.Security.SecurityException<br />
System.Console.Out.Write(se.ToString)<br />
End Try<br />
Does any1 know where I'm wrong ?
thx

Try dropping the "Trusted Connection" portion of your connection string. Also, make sure that the UserName and Password is setup correctly in the SQL Manager so that the ID has the correct rights to the database it's supposed to.

back from holiday....
The problem is not in that way. I've heard something about a policy that you have to create to establish a trust connection between the client and the server when there aren't running on the same computer.

|

It's not so much a policy ... I think this[^] is what your referring to...

Your right but I've heard about a method to use with application.
I've got about 500 Pc and I don't want to add all one by one on my windows 2000 Server which is not an Active Dir.

In that case, you can't use a trusted connection. Since all of your machines are not in the same domain, you can't use the same username/password (or SID) for each user that accesses your SQL server. A better method to use, in your case, would be SQL authentication using an SQL user ID and password that is specific to the database you want. This actualy offers you better security because the SQL user ID doesn't have any rights to any other part of the server that is hosting your SQL server. This means that the ID can't be used to open any shares on that box, or anything else for that matter, just the database, tables, views, stored procedures, ... that you specify in the SQL Enterprise Manager.

I am not sure if this is the proper forum...
I am looking to create a VB.NET based Forms App that will interact with a Web Service. I want to have a main/UI thread that spawns a thread to handle the web service. How do I then, communicate between the two once this is done? I will need to have the Web Service handling thread send information back to the UI, but also have the UI thread send new information back.
Can someone point me in the right direction or to some articles? I haven't had much luck and, with what I have found, have more questions than answers.

I have a VB6 app that needs to send keys to a message box. Is there a way to use the SendKeys method to do so or is there another way? Also..is there a way to execute the next line of code if a line is interupted by a message box... kind of like On Error Resume Next only instead of an error there is a message box?? Thanks for any help.

You'll find that the method you've chosen to control another application is problematica at best...
You can use the AppActive function to switch the input focus to the window you want (all you need is the exact title of the window) immediately before using the SendKeys function to send the keystrokes. The problem is, the user or another app can steal the focus at any time after the AppActivate function returns. This means that the focus can be moved before OR DURING the SendKeys function. There is NO ERROR when this happens. There is no way you can catch this situation and handle it. Using SendKey, this is just something you have to leave to chance...

Ok..now what I'm really trying to do is find a work around for the Outlook Object Model Guard. The vb6 app gets and sends email through outlook 2003. The Redemption[^] library works well but what about when its time to upgrade to Office 2005 or something?? We have a lot of apps (web and windows)that use Outlook 2003 and we dont want to have to go through each of those in a couple years and clean out all the redemption stuff if redemption doesnt happen to be around.We really need to find a work around without using third party software. Thats why I thought about using SendKeys. I need some code that "watches" for message boxes so I can SendKeys to them as needed.

Your only work around is to disable the security through policies. But, that would also let the email worms do what they want to. There is no easy way around this. The "SendKeys" method is also not a method I would in production. It's just to unreliable...

I have a VB.Net Windows service that needs to access a network drive. The code works as desired as a console app on the server but fails on the network share access as a Windows service. I have used both the Local System account as well as the local admin account to run the service. Same results both times. In ASP.NET I know the work around is to use Identity Impersonate in the web.config file but this is a Windows app not a web app. Any suggestions are appreciated and I apologize for the cross post.

You've used both the Local System account and the Local Admin account, neither of which has rights to the network share. You have to run the service under an account that has appropriate rights to the local system AND to the network. That's why the app ran fine in the debugger. It was running under YOUR account.
