Lookup Tables To Display Names Instead Of ID's In A DataGridView
Jul 17, 2009I've been trying to use lookup tables to display names instead of ID's in a DataGridView using a DataGridComboBoxColumn and have even copied the example shown in the Forms over Data videos produced by Microsoft but still get the following error message:System. =Argument Exception:DataGridView ComboBoxCell value is not valid..Everything was done in the designer and the problem only occurs with the DataGridView; lookups work fine using a combo box when displaying single records.Also the error message only pops up when I close the form. Prior to that all the names are displayed correctly for each record, the drop down list shows the names correctly and I can edit, add and delete rows and save all my edits with no problems. Its just when I close the form that the problem occurs.Each time I press OK in the message box the names in the combo boxes are removed, one by one.
View 5 RepliesSQL SELECT With Multiple Tables To Datatable/DataView Get Table Names
Feb 21, 2011For my app users can enter a SELECT statement themselves. This can be any select statement at all, it will be mainly used for creating a quick view e.g. SELECT * from table1 LEFT OUTER JOIN table2 on table1.id = table2.id.
Whatever this select statement maybe I load it into a datatable (after checking for no nasty stuff of course) in vb.net. I want to know the table names so I can query the database again for validation purposes on things like datatypes etc.
da.SelectCommand = New SqlCommand(sqlStatement, tempDB.Connection)
da.MissingSchemaAction = MissingSchemaAction.AddWithKey
dt = New DataTable
da.Fill(dt)

Joining Two SQL Server Tables Together
Jul 17, 2011I am not sure if the above title is suitable for what I mean, but basically my application has a login table with entry U_ID and I have also created another field in my other table which will store this ID from the login table.
What I want to do is, if a user with say U_ID = 1 downloads data and stores it in the
second table I would also for trackable reasons be able to store the U_ID of that user
in the second table so that I would know who downloaded the information.
How can I acheive this and if there are any example then point to them.

Sql Server - Get Column Names From Blank Stored Procedure Data Set
Oct 31, 2011I'm currently writing a small app that takes data provided by an SQL stored procedure and makes it available for easy export for non-tech savvy users. I'm trying to make this as generic as possible, in that you should be able to plug in just about any SP and follow my template to have an export utility. I'd like to add a way to get the column names before running the SP from the SP itself. I had assumed you could just run the SP with impossible values so nothing is returned, then get the columns from the resulting VB.NET DataTable. However, if there is no data returned, the column names aren't returned either. How can I get the column names from the SP without having to hard-code them?

Keeping Tables Cached On Server In Project
Mar 7, 2010I have an ASP.NET project which is a front-end to a database. In addition to the large tables, the DB contains a few small tables to help normalize the larger tables with common values. I have a VB.NET project which loads the smaller tables into memory, using "Shared" (i.e., "static" in C#) member variables, and uses them. I have a call to load the tables in Global.asax - Application_Start. This works for a while. That is, Application_Start runs when I first run my project, loads the cached values, and will correctly keep them in memory for a while.
What I'm seeing (when running my project via Visual Studio 2008 Debugger, hosted locally) is:
A) The Application_Start code will run more than once. Not in a row, but after the user has navigated to some other pages, I'll see (my breakpoint in) another call to initialize the cache, coming form Application_Start. Is it expected?
B) The "Shared" variable that was set to True when the cache was initialized is now False again (which should only happen when the class is first loaded). Similarly, all the data that was chached is no longer present. That is, it looks like VB is unloading all the Shared members. Is this expected?
Making XML In SQL Server Faster - Convert To Tables?
Feb 22, 2012I have a field in the database that is XML because it represents a class that is used in C#/VB.Net. Problem is after the initial manipulation most, but not all, of themanipulation is done in SQL Server. This means that the XML field is converted on the fly.As we are getting more fields and more records, this operation is getting slow. I think the slow down is the converting all of those fields to other data types.So to speed it up I was thinking of a couple of ways:Have a set of tables that represent the different pieces of the XML data. I would make these tables read only using a trigger on Insert/Update that would reject any changes. My 'main' table with the XML in it when it updates the XML would turn off the triggers, update the tables with the new values then turn the triggers back on.
The only real reason we use the XML is because it's really easy to convert it to the class in C#/VB.Net. But I'm getting the point where I may end up writing a routine that will take all the bits and pieces and convert it to a class and also a function to go the other way (class -> tables).
Selecting TOP 4 Records From Multiple SQL Server Tables?

Update Local Tables From Remote Server?
Apr 19, 2010I have an off-line project. User uses a laptop to input data off line into local SQL server express. Once connected to domain (on line), local data will sync with remote SQL server using sync framework. (It is done, works fine)One job left:Since another user used another program to update some tables in remote SQL server, such as CUSTOMER, SHIPINFO, my off-line program need to update these new data once connect to domain.Here is what I design in Pseudo (take CUSTOMER as example)
1) In remote SQL server, create a store procedure (sp_customer) to select all CUSTOMERS
2) In application, create a dataset (dst_customer) based on sp_customer
3) Insert all customers data which is in remote SQL server but not in local SQL server based on CUSTOMER_ID
Sql Server - Join Tables Based On A Column Without Creating Records For Every Combination
Mar 20, 2012I have two tables as follows:
Customer | Product
------------------
A | Car
A | Bike
A | Boat
[Code].....
If I use a normal JOIN then I get a list of friends for every separate product. I just want the two lists once.
The output lists with '-' need not be table cells, they can be <ul>s.
How can I achieve this? I would like to bind to ASP.net GridView. Should I try to do it all in one query, or use multiple queries and somehow add them both to the same Grid?
Each row actually forms part of a long report. Essentially each row of the report contains Customer ID, a bunch of other fields which match one-to-one with Customer ID, then the two lists for each Customer ID I described. Perhaps I can use a separate query for each list, then manually add each list to the grid on RowDataBound or similar?

I have edited the column headers and set the column names to the same values as my table names yet the data is not showing in form load I have set datagridview.AutoGenerateColumns = False I know the data is there if I delete datagridview.AutoGenerateColumns = False then the data is shown with the default headings?

View 8 RepliesC# - Decompiling .Net Assembly Produces Code With Invalid Member Variable Names; Names Starting With $STATIC$?
Sep 5, 2011I am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:
private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;
why the generated code has these invalid member variables?
