IF Statement To Check If Textbox1 And Textbox2 Are Blank - Notify User That Must Insert A Value
Jan 22, 2010I am practicing abit with For Loops. My code works fine which i am very happy about. I have now moved on to inserting an IF statement. I want the IF statement to check if my textbox1 and textbox2 are blank and if they are to notify the user that they must insert a value. I thought this would be quite easy to do however i think i was again ignorant to the coding! See below.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim answer As Integer
[CODE]...
I want to concentrate on the IF statement only as the For loop is working just as it should. When i run the program and leave both textboxes blank and hit the button i receive an error saying 'Conversion from string "" to type 'Integer' is not valid.'
OleDbDataReader From Excel Gives Blank Line
Apr 8, 2010I am creating an application which uses OleDb to connect to an Excel spreadsheet and read the data into DataTable. The problem that I am having is that some of the columns I am getting are coming up blank, I've managed to narrow down that this is because that the first few lines for that column are blank. As unfortunately this is valid in the context of the Excel spreadsheet as not all dates etc. are required to be filled in. I was wondering whether anyone knows of any way that I could go about ensuring that the columns are populated by the OleDbDataReader even if the first x number of rows have that column as blank.

View 3 RepliesReading EXCEL In 2010 Detecting Blank Cells
May 16, 2012My Visual Basic .Net 2010 application reads data from an EXCEL spreadsheet which will be generated by my "customers". The responses to Alkis last year (23 July 2011) has been a big help and got me over a hump in my application. Now I am down to the last issue - how do I detect a blank cell? Valid data is numeric, starts at a fixed cell (A5 to be specific), and will be continuous until it ends with blank cells. While blank cells appear to print a "zero", when I try to use zero as an end criteria I get a 'System.InvalidCastException'. When I put in a specific end value (-1) in the last cell all works fine but that, of course, is an invitation to a user error.What is the difference between "Value" and "Value2" and where might I find documentation that explains the difference?

View 1 RepliesReading A Blank String From Excel When Trying To Read The Header Of A Data Column?
Aug 25, 2011I use an OLEDB connection to read from an excel database, and this loop to read in all of the data from each of the columns
While reader.Read()
For i As Integer = 0 To reader.FieldCount - 1
temp = reader(i).ToString + ControlChars.Tab
output_file.Write(temp)

Some of the columns contain date information, which are read in fine (usually as a string "2/20/2011" or so), but the headers of those columns are read in as a blank "". The headers for all the other columns read in fine, but not for the date containing columns.

Screen Blanks After 1 Min Of Processing (of Excel File) / Refresh Or Freeze Screen To Avoid Blank Screen?
Jun 29, 2011BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?

How To Insert Row At Top Into Excel Spreadsheet
May 7, 2010I am taking a pre-existing excel spreadsheet and inserting a blank row at the top. This part works, the part I am having problem is the fact that based on the code I have, I have to open the spreadsheet so when you execute the code the spreadsheet opens. Then when done, close it. When I try to close it wants me to save the document, even if I call the save method. This whole process should happen behind the scenes so I really don't want the spreadsheet opening.
See code below.
moApp.Visible = True
oWB = moApp.Workbooks.Open("I: estcsv.xls")
oWB.Sheets("testcsv").Rows("1:1").Select()
moApp.Selection.insert(xl.XlDirection.xlDown)
oWB.Save()
oWB.Close()
'When call the close, it still asks me to save the spreadsheet even though I called oWB.Save above.

View 6 RepliesOLEDB For Excel: Inconsistent Insert Results?
Jan 13, 2010OVERVIEW:I am currently having an issue loading a large number of rows into Excel. I say large because the attached code in fact correctly inserts 50 rows into an Excel worksheet, however, as the number of rows increases to no more than500 rows the data is not inserted into the worksheet. No error is thrown by .net and the .xls filesize actually shows an increase in size, however, when the file is opened there are no rows in the spreadsheet..... Then, when the .xls file is closed the filesize is once again reduced.
Again, the code works for a small number of rows. Are there any known bugs with the OleDB driver for Excel?ADDITIONAL THOUGHTS:I have tried inserting rows to both Excel 2003 and 2007, same issue.I have tried closing the connection after each insert.... performance if horrible and it does not fix the problem.I have wrapped the ExecuteNonQuery in a transaction.... no go....
