I have a project that uses the asp chart control. The project was developed to use .net 4.0 but the server uses version 3.5. I changed the project to 3.5 but now my charts don't work.When I change it it tells me that system.web.DataVisualisation.dll will be removed.
View 1 RepliesI have several asp.net website projects for various sites.Currently I want to add REST API's to these projects so I can start developing mobile apps (using HTML5/JavaScript/CSS3 and PhoneGap) that make use of these webservices.
Since WCF is far more powerful than regular asp.net webservices (among others with control over the service and authentication/authorization), I'd love to add these to my existing website project.
I did a Google search but cant find anywhere a step-by-step tutorial how this can be done. And also if there's any functionality I'd possibly loose when adding WCF functionality.I was also thinking of creating a new project specifically for WCF, but think I'd rather add it to an existing website project.
I am running vb.net in visual studio 2005 and i am fairly new to it all, whilst trying to create a windows application i have lost the .vbproj file and am only left with the .vb code that has been created whilst i have been using the toolbox to create the application graphically. Is there anyway for me to recover the .vbproj file without having to redo the whole thing?
View 3 RepliesIs there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

I am using Visual Basic 2010 Express. I want to put an icon my Application to make it look better instead of the regular [IMG]C:Documents and SettingsJake EhrmanDesktoppost 1[/IMG]
I have the picture saved as an .ICO so i can insert it but i want it like this... [IMG]C:Documents and SettingsJake EhrmanDesktoppost 2[/IMG] how would i go about changing the icon for the project file?
I actually don't care so much about the name of the project as I do the .exe it builds. So I went into the project properties, goto the Application tab and change the Assembly name. But when I build, it loses the resources I've included. It builds w/o errors, but the icon's and pictures I've included are not in the program, and then the IDE gives me errors telling me it can't find those files.
I do have those resources in the program, their persistence is set to "Embedded in .resx" and their Build Action is set to "Resource". They work fine in the designer and show properly, and they build and show fine w/o changing the Assembly name.

View 2 RepliesFrom my DLL project I have succeded in making AutoCAD launch by pressing F5 from VB.net IDE (Visual Studio 2008) en route to try to make debugging of the DLL easier ...
... however one last obstacle is currently in the way and the obstacle is that for some reason when I hit F5 and AutoCAD is launched my breakpoints are not recognized at all... and program runs from start to finish instead of allowing me to debug ...
It issues a strange message which says "The following module was built either with optimizations enabled or without debug information... to debug this module, change its project build configuration to Debug mode..." and it is all weird because as far as I know I am not in release mode .. but in debug mode (anyhow I am relatively new to Visual Studio .NET so I am thinking that my impression could be that I am in debug mode when in actuality I maybe in release mode)...
Here is why I think I am debug mode ...
1. From Solution explorer ... when I click on the Solution Name and view its properties ... the Active config property says Debug|Any CPU
2. When I look at the properties of the project and look at the compile tab it says that the Configuration is Active (Debug) and under Platform it says Active (Any CPU).
3. Under the Advanced Compile Options of Compile Tab from project properties ... Enable optimizations is UNchecked ...
Anyhow with all the settings mentioned above it seems that I have everything okay but then the message above proves otherwise ... and so at this point I know that I am still missing something ... like a setting somewhere... wondering what else do you think am I still missing?
As additional info...there are seven projects in the solution and it is the main one (the one that I set as startup project) whose properties I refer to in all the paragraphs above.
I'm searching for a way to change the font size of selected text in a RichTextBox (rtf) having different font families (e.g. Arial and MS SansSerif) and font styles (underline, bold...) using the FontDialog, but without changing the families and styles.

View 5 RepliesFor reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

View 2 RepliesI'm a complete noob to VB.NET and have just made a tic-tac-to game and want to make it multiplayer over the the internet with direct conection via IP address (like CFS3 and the like).
The only thing is I have never used the this before and have searched loads on google and on this site, I just can't seem to find anything that I can understand so if anyone can help me out with where to start getting two machines talking, I have used the WINSOCK tool in VB6 before but didn't really understand it.
I have used sockets in VB6 before but cannot get the same functionality to work in VB.net. I have two machines running VB code and I want the applications to exchange information via a network connection. Using VB6 and socks it was easy but I just can't figure it out in VB.net.The data exchanged are string messages; there is no interaction between users it's just the applications exchanging info. The one machine will always be the server and is running a windows forms application which I'm writing in vb.net (it's actually a satellite antenna controller) the other machine is connected by an Ethernet connection (private network these are the only two devices) and is also running a windows forms application which I'm writing in VB.net (this is the remote controller for the satellite antenna controller) Can someone give me a pointer to some simple code that opens a connection and I can read and write between the two (both ways) using string messages. I' am assuming sockets are the right way to go? Everything I research keeps coming up with console applications

adding certain functionality to an existing ASP.NET application running on IIS 6.0 programmed in VB.NET.To aid in future development the client wants the additional functionality to be as future proof as possible. Ideally i have said that I would like to push for a solution using ASP.NET MVC3, running off IIs 7.5 and .NET 4, written in C#. This solution would act as a seemless addition to the current web-portal appearing probably just as an extra tabbed page.
But they will be completely seperate web-apps. Which is crucial.The main problems i can forsee are firstly sharing session particulars between the asp.net web app and the new application. Particularly with regard to maintaining session state (and not having IIS timing out on one of the apps). Also, conjoining the two "apps" appears problematic in my head, although this may be far simpler than i fear.
1) Embed the new fuctionality into the existing codebase (not a great option). This would mean losing any potential future upgrade-ability and also means not following better OO conventions by utilising the MVC framework.
2) Using an iFrame to link to the razor pages of a seperate MVC3 app (the one im favouring currently). Allows uses of all new technologies, however downside is sharing session data. Either through iFrame "attributes" through persisting a session state to a db? (slow?) or even some kind of web service interaction between the applications to push/pull user/session data?

View 2 RepliesA little but pissed off at the moment as I have just lost a few hours of work. While I was trying to get a form to resize better (so you can make the form bigger and have all the panels and therefore things inside the panels take up the same percentage of the form), I thought about looking in the designer code to see if anything in there would be easy to change to make it work the way I wanted.
Upon finding what I thought was going to be a good bit of code to edit (code that placed the panel in position), I changed it so that panel2 would find where panel1 was (in the y axis), add panel1's height onto panel1's Y location and use that value as panel 2's Y location:
Me.Panel5.Location = New System.Drawing.Point(0, Panel1.location.Y + Panel1.height)
When I switched back to the visual designer view it came up with a warning page (blue bar across the top of the page saying "To prevent possible data loss before loading the designer, the following errors must be resolved:".Therefore I went back into the designer code and deleted what I had previously done and was a little bit annoyed that I couldn't use that code which I hoped I could.Upon going back to the visual design page everything was gone so I went back to the design code but everything was still there.I sighed in relief and ran the program and everything loaded properly so I decided to quit and reload the project to revert to before the incident occurred to be able to see the design in design view.When I reloaded the project everything was still gone and I then found out that the code from the design had gone too meaning I had lost it all. The code that I created would work in the vb coding, I have tried it.

I have a treeview which has lots of files listed in it that it has downloaded so far in it & I want to make it faster/easier to save files in my program rather than clicking save 100 times, is there a way I can make it so they can physically drag the item out of the app to a desktop/folder & have it save there? I am willing to do whatever coding it takes but just need a basis for how it maybe done.
Like I have a lot of files listed under multiple treeview items too though so can I also make it so when I drag a certain item it will make a new directory with all the files under it included? For this all I need is the basis of where they dragged to & what item they dragged then I can make the code to actually put everything where it's meant to be but I don't know if this is possible. I don't want to keep using the slower method of clicking save on each individual file or even the whole tree of items, while pretty quick I just want to do drag+drop instead. I will keep both methods in the program but have drag+drop in it I think could be really useful, I don't need to drag files into the treeview though, just drag items from treeview out to make it save the file(s).
I am looking at adding in some bluetooth functionality to my vb.net application. I require it to couple with a specified mobile phone (that is found by the app) than to be able to retrieve contact information, phone calls (made and recevied) and images from the phone.
Can anyone tell me what my best approach will be for this? If there are any good third party solutions that will do it? If it is actually doable? Im thinking that it should because im basically mimic'ing what all the new fancy cars do with their bluetooth phone compatibility.

I need to extend the functionality of the ToolTip control...Problem: I need to show some introductionary instructions to my users the first time they see a new form based feature in my app. Something along the lines of: '...Welcome to the blah, blah, blah feature. To do this, click that, mouse here, press that so on and so forth...'
Then I want a 'Don't show this again' check box somewhere near the bottom so the 'welcome screen' can be supressed. Currently I'm thinking of loading an app wide form (Public Dim frmMyToolTip as frmToolTip) and using it's .TopMost property to ensure that when I show it, it appears over my modal form (I can Hide/Show at will.) Also without a caption or border, my users can't move it.
As it will be displayed on top of a Modal form, I need a Background worker component to run a timer which will hide the form after a set period. I can store the state of the CheckBox to stop the form from showing next time if user does not require it.
