Reading A Blank String From Excel When Trying To Read The Header Of A Data Column?

Aug 25, 2011

I 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)

[code]....

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.

Finding Maximum Value In Column Of Table?

Nov 9, 2010

I've tried to use the DMAX Function in my VB windows application to find the highest value in a column in one of my tables, however it doesn't seem to work. After doing some research, I think that the function is only relevant to VBA, although I could be wrong.

'show me the maximum HCCID - DMAX
'Dim HCCNUM As Int32
'HCCNUM = DMAX("[HCCID]", "tblHCC")

How to find the maximum value in a column in one of the tables in my database?

Finding A String Between 2 Other Strings That Has A Minimum Length Of 5 A Maximum Of 7 And Contains 2 Dots

Oct 5, 2011

What I need to do is find a string that can be any value, and is placed between ">" and "</" with a minimun length of 5 and a maximum length of 7 and contains exactly 2 dots.

So if I have a text file like this:

<a href="www.site.com">a site</a>
text<br />
More test<br />

[Code]....

I want it to find only the 5.0.77. And no, the number isn't always between h2 tags, and the number isn't even always the same. The only thing that is static about it is that is is between ">" and "</" and that it is between 5 and 7 characters and contains 2 dots.

DataGridView Not Allowing Integers / Doubles And Strings In Same Column

I am using an oleDb connection to connect to an excel spreadsheet (.xlsx) file and load the information into a datagridview. From there I hope to have it edited by a person and programmatically at runtime. However, I noticed that when I import a file that has integers in a column, it will not import any of the string values in that column. Also, It will not allow me to manually enter strings into that column at runtime - it results in an error stating: [Code]

VB GridView Control Does Not Allow Code To Access Column When Column Has Visible Property Set To False

Apr 1, 2010

VB 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.

Datagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?

Feb 13, 2012

It 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?

Private Sub DataGridView1_ColumnHeaderMouseClick(sender As Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick

Copy Files From Excel Column?

Sep 28, 2011

I have many files at work that need to be copied from one directory to another. However, I do not need to copy all the files at once.

I get excel sheets with the list of files that need to be copied once a week. So, in the main directory there is about 150.000 files and I only need to copy about 800 at a time.

I am thinking of having a textbox and an open dialog so I can pick the directory the main files are at - another one where I can choose where they will be copied to.

The problem is the list will be in excel sheet (column A). How do I have vb.net (2008) see the file names in column A and find them and move them?

Right now, I have macros in excel doing the job, however, I have so many things in this excel I need to transfer this part out and into vb.net.

The macro in excel doing the job is:

Code:
Sub CopyFiles()
Dim objFSO As FileSystemObject
Dim strSourceFolder As String

Delete On Column Header In Excel?

Apr 26, 2012

Looking at deleting columns in excel and have found several threads that show how to delete an entire column which I have tested and done successfully. These columns were all identified by "A", "B", "C" and so on...

I was wondering if it was possible to do the same thing using the column headers. When deleting the columns in excel, one has to keep in mind that columns deleted from the left will shift the entire sheet to the left and if one is not careful, the next column[code]...

Let's say a user wants to delete the 'Middle' column (assume as column B in excel) and then delete the 'Suffix' column (assums as column D in excel). If they don't know to work from right to left when deleting columns, they would write code that would delete Column B and then repeat that code for Column D. However, once column B is deleted, all columns will shift left, which will result in the 'Phone' column (formerly column E now column D) being deleted instead of the 'Suffix' column (formerly column D now column C).

If there was a way to delete the columns by their headers (i.e. Middle, Suffix...) this would eliminate the problem; to me it seems a bit more intuitive as well.
