VS 2010 Import Excel Process Clearing Certain Fields?
Nov 7, 2011
Issue: The .xls file has about 800 records but it's only importing about 480 records. I step through each row and find out that some rows have null values.After spending some time I believe I figured out why this is happening. My first field is a SKU value. The first x rows have all numeric values. Then it gets to a SKU like '1234-SE' and this row doesn't have data. So it's like it takes on the field type of the first data type.Question: Is there a way to order the data before I populate the dataset? I tried to do an order by but didn't work.My current code that is not working as I want.**NOTE: I have tried 'ORDER BY SKU ASC' and didn't work as well.
Sub FillDataSet(ByVal sFile As String, ByVal sTab As String)
Dim containsHDR As String = "Yes" 'Change to "No" if it doesn't
Dim strConn As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source='" & _

I have tried to import an Access Request in Excel. However, the last field (SP) contains Null cells and it seems that it prevents the importation in Excel. There is a way to change Null cells?

I created an e-mail program in VB2008. I have an excel file with a list of all e-mail addresses and attachments to those e-mail addresses. What I want to do is import thethe e-mail addresses and attachments into my program. I want my program to then take each e-mail address (automatically) and insert them with their attachments into their respectable fields in the program. The primary objective is to insert 200 e-mail addresses and attachments. Each attachement is significant to each e-mail address.

I tried searching for a solution, but couldn't find anything, so if I am re-asking a common question, don't beat me too badly. For a class, I have to create a form that allows someone to enter in the names of six students, as well as five test scores each. It also averages the scores, and displays them in a label.
What I am wondering is if there is a way to clear the text from all 36 text fields, as well as the 6 labels without having to do everything individually?
I could certainly go through, and write out txtField1.text = String.Empty 36 times, but it seems there would be a more elegant solution. Also, if there is a way to do so, would the same would apply for putting the data entered into an array, or saving it to a file?

web page has a few fields to allow the user to enter payments. After the system processes the payments, the fields weren't cleared out.so my task is to simply clear them out.[code]The procedure is writing an HTML receipt into the strBody and displaying it to the user.They see the 'File download, do you want to open or save this file' and can open the receipt in ms-word. Without those three lines, the resetting works. So clearly they are messing up something, I just don't understand what.I've got a workaround, but I'd like to know what is going on.Even to the tune of is this a correct way of creating/downloading a document.This in an inherited system, the original designer is long gone.

I accidentally submitted it before realizing that I probably should have selected the "Visual Basic General" forum. I am attempting to retrieve file properties of all files in a particular folder. I have used objFolder.GetDetailsOf... to retrieve the desired information of Excel workbooks saved in Excel 2003 format, but I cannot retrieve the information from files savied in Excel 2010 format.

Okay so my program opens excel, reads a few cells, and closes excel. But, it does not fully close excel and after multiple runs, I have multiple EXCEL.EXE *32 in my process list. It also asks for a save when it's closing when there are no changes being made, is there any way to avoid this? And how do you get Excel to fully close?
[code...]
The program closes, without asking for a save, gets me the data I need, but remains in the process list.

I need to access the current instance of MS Excel. To do that, I wrote the following code:
Imports Excel = Microsoft.Office.Interop.Excel
Imports System.Diagnostics
Private _ExcelApp As Excel.Application
[Code].....
The code runs nice, but it has a problem: After the user close the Excel application (click button X - note: no other instance of Excel exists), if you open the Windows's task manager, its possible to see the process Excel.exe.
If I open and close the Excel application, there is no process Excel.exe, but if I run my code with the Excel application openned, after the user close the Excel application, the process Excel.exe isn't finished.

I have written an import routine, that imports a textfile into a database table, using a schema.ini.In the input file, 3 fields are seperated, that should be concatenated in the import-routine. Does anyone know how I can make that happen...Small part of the import-routine, first lines are the last lines of the programatically created schema.ini.
Code:
PrintLine(intFile, "Col11=mededelingen1 Text")
PrintLine(intFile, "Col12=mededelingen2 Text")

I have multiple textboxes that I clear once the task is done to be ready for the next set of information to be populated into the textboxes when the user opens the next file.In the textbox_TextChanged event I check to make sure there is some text in the textbox before running the code. Since I am clearing the textbox this fires the TextChanged event and causes me an error:

I'm doing an assignment for Uni and in my VB.NET form I have some checkboxes, I'm trying to loop through and clear them (I have a button which will clear the form). My problem is that there seems to be no property I can use to set the state of a checkbox when not explicitly telling VB which checkbox I want to use. for example, I can go
WineCheckBox.Checked = False
That will check the box, but I wand to DRY the code up a bit and not have to repeat this for each check box I have, this is what I was trying to do:
If TypeOf element Is CheckBox Then
element.Checked = False
End If
I've tried using element.CheckState and element.Checked and both times I get "Checked (or CheckState) is not a member of System.Windows.Forms.Control".
This is the whole block of code:
'clear the controls
For Each element As Control In Me.Controls
If TypeOf element Is TextBox Then

Am just goin on 3 weeks of teaching myself vb2010 and have found a long way to do a simple task. Well it seems it should be a simple task. I have about 12 different listboxes spread over 3 different tabcontrols. There are 3 buttons that load all the listboxes according to which tabcontrol they are in. I found that when populating the listboxes it would not clear before loading the information so it would basically double post, triple post etc. I've figured out one way to do it that I've put in a sub and call the line before the tabcontrols are populated with their listboxes. Here is the sub:
[Code]...
It seems like a longwinded way to do this is their an easier way to have one command clear all listboxes within all tabpages within all tabcontrols on the form??

Basically I have a list box with a collection of strings. The way it works is you select an item from the list box then enter an integer into a text box and it calculates, straight forward.Where I'm getting tripped up is I'm trying to implement a 'Reset' button to reset the list box and text box. The text box is straight forward as is clearing the selection in the listbox:[code]I understand that since there is nothing selected the index is getting tripped up or whatever but I don't know how to stop this. I'm new to VB and programming in general and have been googling for days trying to get this fixed to no avail.

I am trying to import an excel sheet to a sql database. I was able to get it to work using sqlbulkcopy. I am now trying to do it line by line. The code works fine except that only the first row is added to the database. I used a msgbox to ensure that I am iterating through all of the excel values. So I am not sure what is wrong.

I tried searching for someone that has done this, but turned up nothing. I can import an excel sheet to a DGV just fine, but want I want to do is import it row by row so that I can do validation on each field and then if it is ok, put it in the DGV.if I could do it row by row, validate, then add it to a datatable/dataset, then bind that to a DGV.I can't find any example code of someone doing it row by row, only SELECT * which grabs everything and puts it in a dataset.
