I'am new in the VB world, and should translate excel sheets into new sheets.I'am using Visual Studio 2008 (with VB .net I think) and I'am trying to tackle empty rows deletion.Maybe an additional problem is, that some columns having a space (visualy the row is empty and should be deleted).[code]...
View 10 RepliesI have an Excel sheet that looks like this.
View 1 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.
How can I set the column width and leave the top 10 rows empty in order to insert an image into my Excel report?
Here is my code:
If ComDset.Tables(0).Rows.Count > 0 Then
Try
With Excel

I have a sheet which contains various data, from which one of them is dates. I would like a macro that will search through those dates and if it finds a date that is older than 6 months then it will delete the entire row.
View 7 RepliesHow would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.

View 10 RepliesWhen I iterate the media items in a Windows Media Player playlist and set the properties of a user-defined class to the attributes of a media item, the first n rows of the playlist are populated with useful information; however, the remaining rows are empty. If I perform the same operation but access the media items directly (e.g., display the attributes to the console window) then all items in the playlist are populated properly.
Here is an example of the output showing the condition:
Inserting song "The Arrest" from album "Jesus Christ Superstar [MCA Original Cast Recording] Disc 2" into database...

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.
