Get Code For A Datagrid With Owntemplates To Work
Mar 8, 2009
Been trying to get my code for a datagrid with my owntemplates to work but I'm about fed up with it now butI still want the control over what I can do with the data.I'll give you all the code I've been working with.I would like to keep the concept of what I have been doingthe same if that makes any sense, I like just using classesand code behind.If I turn AutoGenerateColumns to false I do fill the grid with the data.Otherwise I'm not filling it with the data, just the text from the labels.Also the TextBox doesn't show either. [code]

I have created a test application to display data in a datagrid, using the Dataset Wizard per the help. All fine - data is displayed.
I then added insert, delete and update queries by selecting Edit Dataset with Designer, selecting the table and adding a query for each action via the TableAdapter Configuration Wizard. In Advanced Options, all boxes are checked, and on the last screen of the wizard it says it has generated SELECT, INSERT, UPDATE, DELETE statements, table mappings, Fill, Get and update methods. The TableAdapter shows four entries: Fill, GetData(); DeleteQuery; InsertQuery; UpdateQuery. On the DataGridView Tasks page, Adding, Editing and Deleting are checked and the data preview shows data.
When I run the application, I can update, add and delete data, but this is not saved.

I have a VS2005 utility that I'm working on that has an Access 2003 backend. A couple of days ago, my boss asked that I change one field in two tables from TEXT to MEMO, to allow more information to be put in. In doing some final pre-deployment testing, I find when I hit my button to pull up the list of tickets, I get the error
"System.Data.ConstraintException was unhandled
Message="Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.""
The datagrid is based on a query I have in the database. The query runs fine, and when I go through the XSD and go into Query Builder, the QB is also returning data. I have made the various changes to the utlity as suggested by Microsoft, but no luck. When I put the two columns back to TEXT, the Grid works fine.
How the heck do I set it up so that the grid will recognise the new data format? The number of characters for the individual columns is set to 37,627 (I believe, it's whatever the default is). I only have 200 characters in my test data. I need to rebuild the whole dataset - this deployment has to be done by the end of the day tomorrow and I have a whole pile of other stuff left to do.

I need to pass the values that I generate from SQL queries back to my VB code-behind window so I can apply a bunch of program functions to them. The queries work like a charm, and look something like:
SELECT Max(Number) FROM .dbo[00Masterlist] WHERE (County) = @County
and then in the next screen of the "Configure Data Source" tool I set up the WHERE and all is well.However, this information is only the beginning of my obligation to the project.It will display just fine in any data view I choose, but that's not what I want it for.I want to code with it from there. I've tried setting up the SQL as a string variable in the VB, but it reads the string as a literal set of characters instead of as SQL.I've tried stealing it from the form it prints to in a querystring, but that got really really messy.

I created this ASP.NET Web application and I can't get the amoritization table(MonthlyPaymentBox) to loop correctly. I think the problem is somehow in my code I am setting the TotalLoan = 0, but I just can't locate where that is happening. I assume this because instead of of starting the current balance at the users input, it starts at 0.

I am a kid who just wants to learn coding with my friend. We bought the book "Microsoft Visual Basic Game Programming FOR TEENS second edition". We realized we were using VB .NET 2008 and the book was programmed in VB. NET 2005. Will the code work. If not, what do I have to change?2) For those familiar with the book, how would I make a Save/Load feature. Where would I add the code?

Would someone advise as to why the cursor position code does not work in the downloaded code snippet this code is from the second tutorial located within VB 2010. The debugger moves through the method but the cursor is not affected in any manner i.e does not move to position 10,10 when called to do so.I am using XP windows 2003 as a virtual machine through Macintosh OS X 10.5.8 -maybe this has an effect somehow?

I have a materials library that I am adding into a database, the library has a number of columns, the one I am concerened with here is the Item Code column.
All Item codes start with 'M' and then have an integer after them (M1, M2, M3.....M9999 etc) What I want to do is to auto generate the next available item code when a new line is added.
The next available code should be based on the last value in the 'Item Code' Datagrid View column but I don't know how to do this.
I have tried getting the next available code from the database but this doesnt work as I want it to.

I have been coding in Visual Basic with Excel for a while and am now getting into using databases within the code. I have been looking everywhere trying to find how one can code for the datagrid width. I have figured out the individual columns but I want to code for the entire grid width. I am trying to code the datagrid to be the exact total of all of the columns eliminating the horizontal scrollbar and then next I will eliminate the vertical scrollbar for any account that has less than five records.

I am using VB.Net 2003 with an Access 2000 database. The program contains three options for the content of a DataGrid, each from a different table. I have finished programming the DataGrid which loads as the default when the program starts.When I run the program the DataDrid appears, but it is empty, except for a small box with a "+" in it. I click the + and the table name appears, I click the table name and the DataGrid is populated exactly as I wanted it.

Basically we ran into where, for whatever reason, we had to put some 3rd party dll in the GAC for it to work correctly. (The assemblies loaded, but had weird behavior and trouble finding types in the loaded assemblies. The app itself is a add in to another 3rd party program, so it must be something about how its being loaded.) So I tried to write some quick code to handle this without having to manually do this on each machine it was needed on. This is basically what the code boils down to:
Dim X As New System.EnterpriseServices.Internal.Publish
X.GacInstall(name)
Where name is the filename of the dll. This runs without error. It even add the assembly to the GAC. However, the application still experiences the same issue until you manually add the assembly in .Net Configuration window.

Assume an application uses the Dim SalesArray(1 to 10) As Integer instruction to declare an array named SalesArray. The array contains 10 sales amounts. When the user clicks the DisplayAverage button on the form, he or she should calculate and display the average sales in currency format. The code for the DisplayAverage button doesn't work. Fix it.
