The default MDI parent control has a large "desktop" area that can display multiple child forms. Users can drag forms to the edge of this desktop area so that most of the child form is off the screen. (A scroll bar then appears in the MDI parent) I don't like this feature. Is there a way to lock down the edge of the desktop area so that the child forms remain fully visible?

I have a richtextarea with a bunch of text in it. I would like to somehow make it expand to fit all the text without showing scroll bars. I would like the width to stay standard and the height to expand. Is there a good way of doing this? I planned on looping through and adding a pixel to its height every time.. and then checking if the scroll bars are visible. There is no simple way of doing this in vb.net that I can find without using windows api specific methods.

View 1 RepliesBasically back in VB6 days, I created several VB6 apps with Access as the backend database. I'd package my Access db file with the application setup, which copied it on to a shared network drive, and then different computers on the LAN could use the same backend database file, and that worked just fine. With SQL and VB .Net, I've done work with a SQL database hosted on a remote server, so you can basically build your query string easily and anyone can connect to it from anywhere, and it works just fine.However, what I'd like to do is have a local SQL express database as the backend for a VB .Net application and make a setup program that can install it in a way that it could be shared on a Local area network, without the user who is installing the application do anything.
I know about building a connection string with the local machine name, but I don't really have any experience with including an actual MDF file with the application. Does anyone know how it works, and is it a better approach? Does it work similar to placing an access file in a shared unc path?I know that ClickOnce (which is awesome) can install SQL express easily on a user's machine. However, the key is that I want SQL express to be installed only on the machine that is going to be the database server in a LAN enviornment, and not on every machine, unless it is neccesseary. And then how does your VB app know how to build the connection string to access the database from any machine on the local share?

View 1 RepliesI am currently working on a multi branch desktop based project using VB.NET 2008. My Admin want to see the list of currently working branches and not working branches. Additionally they want to know how long a branch is not working.
To display the offline branches I first take a ListBox control named lstListBranch and then upon that control I take another ListBox control named lstListTime to display the offline time.
I want to permanently hide the scrollbar for lstListTime control and want to scroll lstListTime when lstListBranch is scrolled.

View 1 RepliesI have an application that is written in VB.NET, using the System.Windows.Forms.Form as the front-end GUI. It runs perfectly on my Windows machine however recently there is a business requirement to convert this application to run as a web application so that people could view them in their blackberries when they go to the URL. Is there any quick way to perform such a conversion or I will have to translate the code line-by-line for such cases?
View 1 RepliesTrying to set the viewable area to a smaller screen area and have it cycle through as the person moves using collision detection to move the backgroudn image. Here is the start but its off to a bad start so far.
Public Class Form1
Dim Mapx As Integer = 600
Dim Mapy As Integer = 2000
[code]....
Basically the forum size is set to 600x2000 but the client should only allow you to view 600x600. I want it to add +1 once you "collide with a invisable box I'll add and this will redraw the screen.
I designed a form and managed to fit graphics inside it. Picture box is 465 pixels high. Form1 is 500 pixels high. SnapShot of the screen verifies that the 500 pixel height is the overal height. It includes the upper Bar and lower frame. Is there an instruction to set the From's inner pixel size and not overal?

When switching to a new desktop it starts a new instance of my app in that desktop (works) and on the form load event it says process.start("explorer.exe") <- here is the problem. It only shows a window not the actually bar.Also this may be important it shows the window, but when I navigate to explorer.exe 'C:Windowsexplorer.exe' and open it there. The explorer bar does show up.

View 10 RepliesIs it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).

View 4 RepliesIn an article in techrepublic about 10 tips to go from a beginner to an intermediate developer
one of the auther's suggestion was "try to become an expert in at least one area of focus" and learn advance idea in depth about that area. With this in my mind I have programmed for about a year mainly for database application in .NET envirnoment (VB/C#), Currently I want to focus or be an expert in at least one area of .NET environmt. As a resutl I had skimmed some area in .NET such as WCF,WPF, ASP.Net MVC ...etc (just reading an overview of different books). My current job . also demand on database programming mainly for desktop application.
So can you suggest me a list of areas of focus in .Net where I can delve on it beside my current job.
I am not sure whether they can be an area of focus I had some ideas such as SOA with WCF
MVC web application Database design and modelling
Edit @sajoshi I have some strength on data modeling and objected oriented design and mainly I like to work in domain modeling and object persistance with ORM tools.I have little interest on UI design.
I have the latest versions of VS 2010, .NET 4.0 and MVC 3 and I have a problem using areas in asp.net mvc 3 when using vb.net.
I do the following:
Create a new visual basic asp.net mvc 3 project. Select Razor as the "View Engin" and call the project "TestApp".
Create a new area called "Test", it will be in the folder: /Areas/Test.
Add a new empty controller called "PageController.vb" in /Areas/Test/Controllers/".
Add a new folder in /Areas/Test/Views/ called "Page".
[Code]...
These are identical with what you get if you repete steps 1-7 and use c# (only difference is that you will get c# code that is equal to above vb.net code).
I repete: If I do the steps 1-7 in C# it works, but it will not work in vb.net!
I would like to use Graphics.FillRectangle or Graphics.Clear with semi-transparent colour (e.g. ARGB=128,0,0,0) to darken entire area of the Graphics object except some specified (rectangular) area:I know this can be achieved with four FillRectangle calls, but I wonder if it cannot be done easier.I am aware of simple clipping (Graphics.SetClip), but this allows me to clip everything outside the specified area and I would like to achieve the opposite.
