Checked Listbox Gitosh18-Jun-06 23:46 Gitosh 18-Jun-06 23:46  Hi guys, I'm on role based security thing. I have a roles table , a users table and a UserRoles table which contains User Id and Role Id (both primary keys). For assigning roles to the users, I have a form which has a combo box for listing all the users and a checked listbox for listing all the roles. To assign a role I select a user and check the role I want to assign. That Information is stored in the UserRoles table.The problem is when I load the form and select a user who as been assigned roles, I need those roles to be checked.The datasource for the checked listbox is the roles table. Any help will be highly appreciated.

Thanks Re: datagrid Werries23-Jun-06 7:24 Werries 23-Jun-06 7:24  Protected Overrides Function ProcessCmdKey(ByRef msg As Message, ByVal keyData As Keys) As Boolean End Function This sub capture key messages before the form get's it. You can handle the key message manually from here and set the focus to the next control is keyData = Keys.Tab Try this, it's how I manage to control where the focus is on my application and it works fine! A programmer's life is good... or is it?? Ek dink nie so nie!

I've recently arrived in the world of .net from VB6. I have seen applications that can send a method to an object with a compiled executable. For example, the screen capture software called SnagIt has the ability to scroll a list box within any application window that is active. From my experience, the only way to accomplish such a task would be to send a call to a dll file but it would seem impossible to me that SnagIt (for example) would know the dll to hit for a software program that it never saw before. Somebody told me that this functionality is now possible because of the .net technology. Does anybody have any code examples of a VB .net program that can send methods to a control within a complied executable? Thanks, Derek Re: sending methods to an object compiled within an exe Dave Kreskowiak18-Jun-06 18:38 Dave Kreskowiak 18-Jun-06 18:38  You cannot send "methods" to other applications. You can't send methods to anything actually. What you're seeing is SnagIt sending Windows Win32 messages to those controls. You need to get the Window Handle of the control that you want to send messages to, then call the Win32 function SendMessage to send whatever messages you need to to that control. This is nothing new. This is how Windows has worked for years. There's nothing in the .NET Framework that makes this any easier than it was 10 years ago.

After all, that's what you paid the money for...support. Right? Sorry, there's just too many cracks out there for their ActiveX components to believe that you paid the money for the component and are still asking this question.

Are you saying that you're running your own SMTP/POP3 mail servers at home? Most ISP's will NOT allow you to do this.

What do you mean by "some times it take a long time to recive email"?? Are you running your own mail server at home? Are you expecting a message from an outside sender to be delivered to your mail server and you're not receiving it? Or are you saying that the mail message never leaves your mail server and arrives at its destination? By the IP address in your code, I'll assume that your running a mail server on your local machine. Most ISP's will NOT allow this and will NOT forward messages sent from unauthorized mail servers.

Re: sending email Dave Kreskowiak21-Jun-06 1:24 Dave Kreskowiak 21-Jun-06 1:24  That depends on your ISP's SMTP server. But, generally, no, there isn't. As for the CDO.Message object error, you might want to take a look at this[^].

Then show them in a listview by icon view mode. However, the picture is not clear. How to do? Thanks! VB 6.0 Re: Why listview could not show good image? Dave Kreskowiak18-Jun-06 3:03 Dave Kreskowiak 18-Jun-06 3:03  Are the images you have in the ImageList the same size as they are going to be displayed in? Or are they larger images being scaled down to icon size in your ListView? If they're being scaled, your sacrificing alot of image quality doing that. It's best to use images of the size they'll be rendered at, not scaled.

The 2nd parameter of this function is declared as Dim driveLabel As String = Space(200) This string remains 200 in length even though the label returned is only 11 chars long, say "MY PROJECTS " This string delaration is giving me a lot of trouble and it completely messes up the rest of my code when I concat it with other string variables. (eg dim myText = " label is " & drivelabel). Everything become 200 in length. Does anyone know how I can extract the useful part of "driveLabel" as declared above??? That is a string with the correct "string.length" value (for "MY PROJECT " I need driveLabel.length=10) Re: How to extract part of a string progload17-Jun-06 18:40 progload 17-Jun-06 18:40  String.Trim Removes all occurrences of white space characters from the beginning and end of this instance. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemStringClassTrimTopic1.asp[^]
