View 1 RepliesHow To Write A Scalar Query In .NET From A SQL Database
Jul 11, 2011I am trying to write VB.NET query without writing SQL stored procs. I have already gotten many dataset text queries to work. But I am having trouble with getting this scalar query to work. All I want to do is to get the result of this T-SQL query. How can I code this successfully? select (DateDiff(w, '1/1/' + '2011', getdate())) / 7 AS SELECTED_WEEK (What this code does is it returns the current week of the year). And will this query above return the value as an integer datatype or string?
I tried your answers but it gave me this exception error:
System.InvalidOperationException: ExecuteReader requires an open and available Connection. The connection's current state is Closed.

Write A Dynamic Sql Query That Fetches Data From Oracle 10g Database?
Jan 27, 2009trying to write a dynamic sql query that fetches data from oracle 10g database. My Where criteria is giving me real problems but i guess it has to do with the oracle data format. The data column is a TIMESTAMP data type storing values like 25-JAN-09 07.06.01.000000000 AM. Am trying to get rows having the columns matching a specific date( ignoring the time values), my where looks like this

View 3 RepliesBinding DataGridView To TableAdapter Query That Takes Parameters?
Aug 3, 2009I'm trying to bind a datagridview to a tableadapter which contains a query that requires parameters (for the WHERE statement of the query). The datasource is a SQL Server database. When I bind the datagridview in design view, it does not let me choose which tableadapter method I would like to use. The way I've been fixing this is to go into the code behind that form, where Visual Studio puts in some auto-generated code that fills a datatable in the dataset and I change the method that it's using there and put in my parameters. I don't think this is the proper way to do it, however, especially because sometimes that code doesn't even get generated! My other solution is to just programatically bind the datagridview to a datatable which I have filled using the tableadapter. This seems like more work than it should be, though.

Jun 9, 2011The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage.

Large Database File (mdb) Takes Time To Load In .net So Alternative?
Feb 8, 2011I have 4k records in access database. And one of the field value contains ~100 lines each so and one other field has ~25 lines. So total database size reaches ~30MB and it takes lot of time 15-20 seconds to load the database in vb.net using odbc [URL]..and updating of any other small fields also takes time due to database being large
So as an alternative I used rtf file (txt files were not preserving all the newline characters). So these file are around 5-10kb only. But for 4k records and 2 fields I have now 8k files. And copying of these 8k rtf files is taking huge time for 5MB transfer it takes an hour or so.So is there any other alternative for storage of this data. So that it will be portable and easily loaded/accessed/updated from vb.net?
Resources To Write GPS Information To Photos?
Jan 23, 2012I've been searching for days, even weeks for any hint of code that will take my GPS data and write it to a .jpg There are many samples, but read down the comments: Not a lick of them works
This can't be that hard- My boss' phone can snap a picture and ~poof~ there it is. Does any one have any solid resources that can take my GPS data and write that data to a .jpg in a format that Bing maps ot Google earth will process? Many people would like to know. It would be nice if we could get all this information in one thread. If my application is too hard for a 5th grader to run, I've made too complicated"

Write XML Document To Group Information From Two Different Sub Routines
Jan 19, 2012I am trying to retrieve all processes running on a machine with the usual information; process id, name and the memory usage. I am trying to export it all under one xml file, however to get all the information I had to use 2 separate methods. To get the process id, name and session id (process owner) I used the following code along with a dictionary and a class, using a .net library called Cassia.
Using server As ITerminalServer = manager.GetRemoteServer("Spartacus")
server.Open()
For Each process As ITerminalServicesProcess In server.GetProcesses()
If Not String.IsNullOrEmpty(process.ProcessId) Then
dictprocess.Add(process.ProcessId, New Processes(process.ProcessId, process.ProcessName, process.SessionId))
[Code] .....
As you can see the unique id (process id) is the same in each xml. Is there any way I can write the xml so that the information from both methods can be under one tag?
VS 2010 - QUERY The Information From The Databse With Variable
Dec 9, 2011I am almost finished my project for a vb database app, but lack the apparent knowledge to make this last connection. My listbox populates fine on form_load. I have identified the "category id number" from the database as the identifier for my information to be displayed (from that field). The variable catID returns the proper "category id" number to match the information to be returned when clicked (a description is part of the field for the appropriate number)
I presume the extra sub procedure I wrote for another daCategory = New OleDbDataAdapter is probably not necessary, but I'm very confused. How do i QUERY the information from the database with variable catID? tblSamples.Category(#) to return tblSamples.description to textbox when called from the listbox. I am not/will not use a databinding approach. [Code]

The programme that I am writing to has up to 500 line items, by 10 possible suppliers; as you can imagine testing this every time is too labour intensive.[code].....
This code correctly takes me through the various forms until it reaches the Input General Information Form, which opens with the top TextBox in focus. However the entry, "Escravos Gas to Liquids", is placed in the last TextBox.How do I make it enter in the first TextBox, which is in focus? From that point on how do I cycle through the remaining 10 TexBoxes to make each entry?
