Wondering if its possible to move the tabrect areas? For example:
[Code]....
I can already paint the tabs to the new location, but not sure if I have to override onmousedown or onmouseclick or what to have the tab selection area match up with the new painting. I haven't found any example of what I am wanting to do.

I have created an application that has a webbrowser, two radioButtons, button1, and a menustrip.The menustrip has two main heading and under each heading are about 15 Tool Strip MenuItem. The ToolStripMenuItem properties are set to CheckonClick and an example of forum1. vb code for this section of the application is:[code]What I need is for the user to be able to add his/her own ToolStripMenueItems to those already present, along with the base url.So that clicking Button1 sends them to the base url And also have the Radio Buttons automatically add the extensions to the base url when the RadioButton is clicked.They need to be able to do this from the application itself.But I'm not sure how to code this in.They will not have VB to make modifications.

I have built a Dll and a Windows Service in vs2010. Both are targeting the .net 3.5 framework, but when I install it on the server it installs fine, but for some reason it targets the 2.0 framework and any time the methods fire that are using linq it crashes out with a clr20r3 error system.nullreferenceexception. Not really sure why it's not targeting .net 3.5.

Has anybody had this problem? I have a very simple query where I'm using a comma to denote something like - In ("purchase","refinance"). Access says that the comma is a special character & won't allow me to do anything. I have another PC which has all the same MS Access settings that allows me to run the same query. This lets me know it's a setting issue but I can't find it anywhere. Does anyone know what setting would cause MS Access to view a comma (,) as a special character?

I am developing an application in VB2008. I initially starting using Office 2003. But later found out that I need to develop it using Office 2000 automation instead.
The problem is when I developed it using Office 2003 I was able to reference the bookmarks by name like this:
Code:
Dim data As New DataObject
data.SetData(DataFormats.Rtf, pubrtfContent)
Clipboard.Clear()
[Code]....
Why would just changing the references in the application cause the bookmarks to be referenced by numeric value only, instead of name? And how I can I get the bookmarks to be able to be referenced by name in Office 2000? Obviously I am doing something wrong, but can't figure out what.
Btw, when I try and reference a bookmark with the name in with the Office 2000 references I get this error: Conversion from string "Judgement" to type 'Integer' is not valid.

I'm Writing a program for my VET IT class at school, so other IT students dont ruin computers we have set up. the program is working great, with only one problem. the program carries out its task, even during debugging (Although it shows an error.) the problem is with windows. in order to stop users from pressing the windows key, the program turns of windows explorer when run, and turns it back off afterwards. before doing this, windows asks for permission. does anyone know how to use visual basic to automatically interact with this messagebox?i have uploaded a video showing my program in action and the problem.

I have a .Net Console application which displays thousands of lines on the console each minute. I want to convert it to a Windows Service, however I still need a way of viewing these messages. There are far too many messages to write them to the event log or even a standard log file. I was wondering if there were a way to write a systray app that could simply intercept these messages from the service and display them in a console window. I have no need to save older messages, I only need to see current activity.

I have a console application where I successfully have added custom menu item in the application's system menu using the Windows API calls. How do I hook into the events to capture the event raised when the user clicks on one of these menus? All my Google results talks about overriding the WndProc method, but this doesn't exist in a console application.

This may seem complicated but it's a somewhat basic concept, just probably a complicated execution, I am trying to create a program that will allow you to basically "IM" between computers on a LAN network. That's the concept, I plan on doing this by generating .bat files, executing them and printing the last few messages sent in a label, the big problem I have is receiving messages, I have no idea whatsoever how to even go about finding out how to take the messages received from the messenger service and print them into the label, any ideas?EDIT: This is in VB.Net 2008

I've started using the FormView control to enable two way databinding in asp.net webforms. I liked that it saved me the trouble of writing loadForm and unloadForm routines on every page. So it seemed to work nicely at the start when I was just using textboxes everywhere....but when it came time to start converting some to DropDownLists, all hell broke lose. For example, see:

I am writing a program that and like to implement data verification system. It needs to return a unique string for any value entered. My question boils down to: is it possible for an AES function to return the same value for two different entries? The source values will becoming from data held on a magnetic stripe card.

I posted this through my phone originally, and I am now just getting back to this post.
I've been looking around the web and while reading Wikipedia's article on SHA, I see that SHA-2 (SHA-256/224, SHA-512/384) have no detected collisions (assuming the article is accurate/up-to-date). This is desirable. Any recommendations on what version of SHA-2 I should use?

I make an application and make setup file using VS setup project. This work fine and create default text files into Program Files Folder for winodw 7/vista .but can not modify these files or create any new files.
There are few text files need to create ,modify during application running ,but in windows 7/vista unable to create,modify files.I am using full default admin right for these OS. If iuse C: root path then application work fine or for win XP no problem.I think UAC restricting to perform these opeartion. But i do not know how to change these restriction using vb.net, whenever application start.
I found one solution that , if change user rights manually then this problem solved.Follow these step to change your account settings.Control Panel-->User Accounts and Family Safety-->User Accounts-->Change User Account Control settings-->Never notify(Set tab to never notify).After this change need to restart system.Now can make all changes like windows XP into Windows 7.can also make changes into program files.
Its working fine, but need to make these changes manually in OS.but its not efficent solution. So if any one knows how can make these changes by coding that will nice.

I'm developing a program where I've had to add a keyboard shortcuts system. The problem is it uses a third party OCX for a part of its display, and it is catching some essential WM_KEYDOWN messages when in focus, like Ctrl+C, Ctrl+V, etc. I've tried catching the WM_KEYDOWN message through WndProc, but the message is not propagating, so I guess the keyboard messages go from the inner container to the outer one, don't they?
The WM_KEYUP messages can be caught tho, but I'd prefer to be able to catch some of those messages on the KeyDown event. I'm aware I could make some low-level hook, but I'd like to avoid this workaround. Well, if the WM_KEYDOWN message goes from the OCX to its top level container, I guess I'll have to treat those key combinations in the KeyUp event.
