I'm trying to see if Codedom can handle strings and concantination between different languages, without me setting up conditional strings per language.For example, I need to generate the following exactly as shown below in both C# and VB.NET via Codedom:
C#
errorMsg = errorMsg.Replace('"', ''').Replace("
", @"
");
System.Windows.Browser.HtmlPage.Window.Eval("throw new Error("Unhandled Error in Silverlight Application " + errorMsg + "");");
[code]....
The CodeMethodInvokeExpression for errorMsg.Replace and System.Windows.Browser.HtmlPage.Window.Eval is simple enough, it's the string inside them that I can't figure out if Codedom can automatically handle.
i'm dealing with a variable of the type string, in a "select case" code; if the string in it was "5a6-Hor" then some calculatins will be made. the problem is that the value would be "5a6", but the case related wont be applied(the compiler isnt reding it as "5a6"), although i had a msgbox showing the value of the string as "5a6", as was defined under form_load event here is the code:

View 1 RepliesI'm trying to get the list of field names for a given table, to turn them into a string which I can to post back as a variable to another function.I've Googled loads of stuff regarding GetSchemaTable but all I seem to be able to output are field parameters, but not the actual value of these parameters (ie ColumnName, which is the one I actually want!)
Found this page; What is the SQL command to return the field names of a table?But all the queries on there give me an error "You do not have access to Table 'Columns'"I feel sure this is pretty simple, can someone give me a little function that will simply give me fieldNames = "fieldName1, fieldName2, etc"I am using a MySQL server and ODBC connections ASP.NET using VB.

I have a Windows application that uses typed datasets. When setting up the datasets, Visual Studio asks if you want to remember the connection.
Before filling the dataset, I programatically change the connection string of each table adapter so that it will connect to the remote database. Before this operation, it is set to the local database since that is the one I am developing on.[code]...
how do you convert a bidimensional array (of string)
View 2 RepliesFirst I tried getting a SQL query into an array, and then mail it. Made the data incomprehendable. So someone told me to use CSS to build a table format, filling it with the array. A LOT of hard work (since I had to learn css all the way from "what is a css".
Then I was told "Array? why use array when DATATABLES are soooo much easier"
So here we go again. "What is a datatable, and how does it work"
I'm a beginner developer using VB 2008 Express Edition and SQL Server 2008 Express. I have tried my simple problem using many different ways and also have searched the web, LINQ to SQL, SQL commands, MSDN library, MSDN Forums, 'How do I' help document, and ... but come up empty. In my simple Table.mdf (see below), I have created some tables (T1, T2, T3, ...) which none is joined together. What I try to do upon request is to get a value string of specific row and column of table?

I'm trying to use variables in my connection string to a table adapter. The only clean cut method I've seen is the following, however, I'm getting "Invalid Connection string" upon run-time. I'm assuming maybe this can't be done?

'TODO: This line of code loads data into the 'BCPM_DDBODataSet.LTC_FBS' table. You can move, or remove it, as needed.

Me.LTC_FBSTableAdapter.Fill(Me.BCPM_DDBODataSet.LTC_FBS)
Is this possible? Currently I'm using a login form that passes txt box values to string and then use as variables in the hand coded connection string (for each query) is there a way to use this with a table adapter? something similar to how access remembers your login credentials when accessing an ODBC table? I've tried editing the connection string in the config file, but says it's invalid every time. I'm only using the table adapter to populate my form after running a hand coded search query.
This is what i use for manual insert/update/delete query

I need to split a string into parts to insert into a table (Data Grid View).
The string is as follows
map: mp_shipment

Following is the code which gets xml data from web service and then dataset reads using ReadXml method. This Xml has ID and MyDate tags for each table row (so table(0) will have ID and MyDate columns) and this Xml data does not have schema associated with it. When page is loaded first time, it sorts by ID in asc order. It was working until ID was 999. When next ID came as 1000, even in ID asc, 1000 is showing before 999 in datagrid.
I wanted to confirm that when dataset is loaded using ReadXml, all the columns in its table are treated as string even they are numbers or dates and that's why in ID asc order 1000 is coming before 999.
Also, MyDate tag has date in format "01/31/2011" (mm/dd/yyyy) and it seems that sorting is wroking fine for date. Would sorting by date always work even when dataset table MyDate column is of type string (assuming that my above statement is correct)? Are my two above assumptions correct?

I am storing my connection string in my app.config file. I am using sql server express 2005. The connection string on my dev machine is different from the ones at the clients. so each time I update I open the config file and edit the connection string setting.
