Multiple Tables In Visual Studio 2010 (VB) On Data Grids
Feb 13, 2011
I have looked at the answers in the forum and some seem dated. I an an old vb2 person and need to move up. I understand sql very well and use complex queries. First test project and trying to add multiple tables to a data grid (Only Form in project).I used the Data wizard to add the Access data base and worked by way through to near the end. The query works in the wizard and returns the correct rows. The error message is "The solution returned by the new query differs from the base query."
During the creation process I selected all the tables. Reading some of the old anwsers I get the inpression that VB 2010 does not handle multiple tables in a datagrid (forum items go back to version 2008).

I have been trying to find and/or think up a way for data to automatically update a data table.I have a log that shows all the customers that came in today with various information. There could be twenty or thirty employees adding to this log or updating or doing things with that customer. This information is in a Data Table on a ASPX page in Visual Studio 2010 that the code is binded in the aspx.vb page that is calling a page in my APP_CODE database file that calls a query in my Database to get the information.My question is could someones actions on a different computer make my computer refresh or to re-bind that data.I have thought of some kind of timer/counter maybe that looks to see if the count of the log is different.

i notice that when i start next line of code and i press enter, it recompacts itself and the continued line moves left a bit... then if i place focus on the second line and press enter again, it (the second line) moves to the left some more, and it keeps doing this every time i focus on second line and press enter. how can i make it so that my second (and third etc) lines are formatted in a pre-determined way so they are always a certain amount of tabs indented to the right from where my line 1 starts?

I am converting an older software package written in VB 6 to VS 2010.Not to incredibly painful but planning for the future as we have had lets say a few issues with VB 6 on our current layout of multiple OS and this is my first real project lead.We are a smaller job shop and we move on a rotation of new PC's/OS's come in to replace broken or exhausted older PC's in the front office and move the older PC's out to the shop floor.We have an array of different OS's ranging from Windows 98 and Windows 7 (32 bit and 64 bit OS). By the time I am done with the conversion we should be sitting comfortable with a range of PC's from XP and up. When creating the executable for my project is this something that can be handled ahead of time, creating multiple executables for specified OS, or an all in one package executable?I was looking to see what people had as suggestions at handling this.We haven't even bought VS yet and are looking at the VS 2010 Premium package, do I need Ultimate?

how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success.
I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.

im trying to add a new data source to my visual studio 2010 project. As it stands my project consists of a few windows forms. I plan on making it access a database (made in access, unless this is a problem), and be able to perform pre-set queries, search/sort, and basic delete,add,edit functions. I will hopefully be later adding the function to print reports according to the database entries.However, the problem i am having is that when i go on to data sources, and click add new source, the following happens:3, it asks me which connection i will be using, i click new connection, then in the new connection dialog i choose the following : Microsoft Access Database File (OLE DB), then i browse for the database i made in the 'database file name' box, Then i delete the default username in the log in to database bit, as my database has no protection.

Does anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.
At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates
Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?

I am just wondering how I can add Direct X references to Visual Basic in Visual Studio 2010 Beta 2. I cant find them in the .NET reference list, or the reference list, or anywhere. I downloaded the Direct X SDK for August 2009, but I can not add the .dll files to the reference list. Is there anything I can do to add them? I need the references for programming reasons.

Back in Visual Basic 6.0 and prior I could have a picturebox control and then have multiple images on that and using a gif file; then I'd have some images transparent. For example, I am trying to make a map where each country has it's own layer and the void is transparent so the underlying picturebox contains all the water.
However, in visual studio I've noticed the image control is now gone. I tried using a panel and a picturebox on top of that and it works but I can't use another picturebox on top of that picturebox, nor can I stack multiple panels with the same affect.

I have a Windows project in Visual Studio 2010 in which I store all images in the project's resource file that Visual Studio created for me. However, it's getting cluttered and I'd like to separate images into multiple resource files if possible. I created a new resource file, but Visual Studio doesn't recognize it when I go to the form designer and try to change an image. The only file that comes up under the Project resource files available are MyProjectResources.resx. The one that I just created isn't there.

I can launch a program from inside my program and embedded it in my program using a Visual Basic Control such as a Panel. That works well if you launch say NotePad or Calculator.However, If I want to launch a program that uses MULTIPLE forms... all that gets embedded is the Main Form... All the other forms are floating on the desktop nonconstrained... So If I minimize my program the other forms are still shown.So what I am attempting to do is to get ALL the Forms from the external program embedded into their own objects on my form.Have pieced together a program from a couple of program samples that I have seen across the internet... Here's the code so far:[code]The Main form for the program that I am attempting to embed is 384 x 347 in size.Panel1 is a Panel Control on my Main Form."MyProgram.exe" is a program that I have written myself.I have looked at Spy++ for Visual Studio 2003 and it is able to identify ALL the forms from my program.My question is how do I embed ALL the forms from my external program in the NEW Program?

I am working to make a function that will update the back color of a text box based on multiple variables values. I can write the code to do the calculation, but I am not sure how to make the function realize which text box to update (as I will have about 30 different boxes). Below is the code that I have for each box so far, but I will have quite a few more, and would rather use a function to reduce the amount of code, and also make it cleaner as well.
If sngPreviousPrimaryPropertyTotal >= sngPrimaryPropertyTotalCost Then
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightGreen
Else
txtPreviousPrimaryPropertyTotal.BackColor = ColorProgramLightRed
End If
[Code] .....
Or is there a way that I can tell the function that it's updating the text box that call the function in the first place? Say if txtBox1 has updated text and calls the function, then the function 'knows' to update txtBox1, but will update txtBox2 when it's called by txtBox2.

if it affects the run time of a program if I were to have multiple data tables as opposed to one data table with all my data in it? I am trying to minimize datagrids and just use code to access table data, in hopes that it will speed up my program. But I am ignorant if multiple tables vs 1 main table will make a difference because there will still be the same amount of overall data present in my program one way or the other....?

My VB project is large enough that it requires several files. It was originally developed as a Console App and I created each file as a MODULE. All modules could use subroutines, data structures and constants from other MODULES and everything worked fine. I needed to add basic windowing to the app and this required that the app be converted from a Console App to a Windows Forms App. The main window is Form1 which is not a MODULE but a CLASS. The problem is that some MODULE based functions cannot access subroutines, data and constants that are defined within the CLASS Form1 unless they are incorporated into the CLASS file and this makes the CLASS file very large. If I add a new Class file to the project, it also cannot interoperate with Class Form1 in the same way that multi-MODULE code interoperates.
How does one spread CLASS code across several files and still allow it to interoperate as if it were in a single file? Alternatively, how does one create several CLASS files that operate the way multiple MODULE files operate.I am sure that there are all kinds of best practices that I am violating but the goal to to get some prototype software working and interfaced to some lab equipment.
