Here is my problem:I have 2 tables Accounts and Transaction Logs.in Accounts table, it has column "Amount" which is a base amount of an account.and in Trans Logs table, it also has column "Amount" which is additional (add or minus to the base amount) amount of the account.and I don't know how to retrieve that base amount to edit it, then save it back to the table.That means I need to get a value of the right column by using Acc_No to find. I'm using DataSet, by the way.i think it should go like this:
Dim Amount as Decimal
Amount = *the code to retrieve the base amount*
Amount = Amount + txtAmount.Text
*the code to save the new amount back to Accounts table*

How can I replace the "FileInfo" in the above code line with datarow("statusupdate")

View 5 RepliesHow to retrieve the particular column row to the text box?
I mean how to display it in textbox?
The column has got different rows.
The code I wrote in vb net is :
cmd = New SqlCommand("select ida from Issue where aname='" + TextBox3.Text + "'", con)
In the above line I compare the textbox3 data in the table.And if the data matches then it should display the ida that matches with aname row to textbox4.
I know this has to be a very simple answer but I seem to be overlooking it. I have an Access database that I have conected to and have created a DataSet. The DataSet consists of one table with several rows and a bunch of columns. What I am trying to do is get the data for one specific row and column so that I can use this data is some calculations. I can position the row if I need to but I can't figure out how to get the data in the specific column I need.
View 3 RepliesMy requirement is to read all rows of an excel-sheet in first column that are not empty, are numeric and have a length between 15 and 20.
For example:
358218033354974
359473035499561
358218036156129
354022038366247
358218032490035
359473030516492
353210040325399
This column might have a header that is not numeric and there might be empty rows. This would cause an exception when importing them via SqlBulkCopy. So i want to prefilter the correct rows via OleDbCommand.
What I have tried so far is following(C# is also appreciated):
Using connection As New OleDbConnection(sExcelConnectionString)
connection.Open()
Dim schemaTable As DataTable = _
connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, _
New Object() {Nothing, Nothing, Nothing, "TABLE"})
[Code] .....
But this throws an exception if there are empty rows or the format of the value is incorrect. So my question is: How to restrict the rows of OleDbCommand to:
Get only first column of every worksheet
All values that are numeric
Skip empty values
Ideally only the values with a length between 15 and 20
Any way how to skip the empty rows, Or do I have to to select the whole datatable? I hoped it would be possible to do that only with one query because of performance reasons.

Add persistence to multible DataGridView in terms of Hide/Show column and column width
View 1 RepliesVB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

View 1 RepliesIt seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?
