Forms :: Importing 5 X 1000 Data Field Into DataGridView

Nov 29, 2010

I am trying to make part of a form program do the following When I exit a text field, I want to import some datainto a datagridview control.The columns are (1)Key, (2)Location, (3)Part Number, (4)Serial Number, (5)Description.There are up to 1000 rows of data in anyone of the spreadsheets I am working from.By using a datagridview, I can click the header and sort the data by either of the 5 columns, and when I select a data row, the Key number is reported back (for now, into a text box)I will be using the key number to further manipulate the spreadsheet after I have solved this problem.There are thousands of articles on DataGridView, and over the past 8 days, I think I have read them all. I have tried many downloadable routines, which haven't populated the DataGridView at all.Please can someone show me a simple program which will do the above task, and will give me a base to start from.I am running MS Office Pro plus 64-bit on Windows 7 and Visual studio 2010 pro

Importing Data From Excel To Datagrid Or Datagridview?

May 5, 2010

I have a problem loading big spreadsheets into a datagridview.

I had a similar code as above that i used and it works great if you have say 10000 cells to populate cell by cell.

How ever moving to 2 mil cells is a different cup of tea, the code took more than 7 minutes to load the data, and although the data was perfect in every way, its too time consuming, i cant get it to work faster so I used the datagrid instead.

The sheets needed to be imported is 350,000 cells plus. I used code that works realy great, does the import into the grid and transfers the data to a datagridview within 15 seconds with little resources which put a smile on my dail :) then i saw something and it dropped ...

see code:

[Code].....

My problem is that whenever there are values below the heading of the cell the datagrid displays (null)

No matter what i do even converting the values in excel to text it does not display the heading of that column.

When i paste other text into the cells below the heading (NOT NUMBERS) it shows the data and heading, Only if the "type" of content is the same does it display both the heading and the text that follows in rows below.

Exporting / Importing Data From / To DataGridView To / From CSV Or Text File

Jul 15, 2008

I want to export data from a DataGridView to a CSV/text file. I then also want to be able to load that same CSV/text file and populate that same DataGridView at a later point in time. My information is loaded into columns in the DataGridView. That is, I am not using rows to represent records, I am using columns. As such, I need to load all the data in each column and export this, by column to the CSV/Text file. Likewise, when I load the control from the CSV/text file, I need to load each column with this information.How do you export/import from/to a DataGridView controlHow do you organize the data in the CSV/File

IDE :: Importing VB6 Forms To .NET?

Jul 10, 2009

I inherited a DLL project developed in VB6; this project has to be integrated to a VB.NET GUI. At the moment, the project is integrated succesfully except for one detail that it is taking a lot of my time.

Every time that has to load a form from the COM DLL, the execution of the program loops and gives an OutofMemoryError -- I imagine the error is because the executing is looping by trying to load and reload the Form1 from the DLL. So, is it possible to import graphical controls and components along the DLL, such as Form1? or, do I need to separate them in order to import the DLL succesfully?

Importing CSV Files With Windows Forms?

May 2, 2011

I am building a small Windows Forms application. I need to 'read in' CSv files into the application.

I am using StreamReader to read the CSV files into the application. That is no problem. On my Form I have a text box, 3 Buttons and 2 data grids. With the first 'browse' Button I am using OpenFileDialog to select which CSV file I want to display in the first grid.

Then I want to use a 'convert' button to display the information from the CSV file in a much more 'user-friendly' manner in the second grid. Lastly I want to use my 'export' button to export the converted file to excel.

I'm using a datagridview to display data from an Access database. Is there a way to have the columns that are imported be set to fill up the entire datagridview? depending on what data I'm displaying the columns are either too narrow or too long for the datagridview.

Forms :: Writing Data From A DataGridView To A Text File?

Feb 17, 2010

I have been using this code, see below, to try and write data from the DataGridView to a text file. It works but it puts an extra comma after each line and thinks that there has been another line so puts an extra 4 commas on a new line. So the text file looks like this:

9,Here to There,1,15,
8,Hell to Heaven,16,34,

I'm looking for any help for a way to get rid of the extra commas or an entirely different way of doing this whole process.

Windows Forms Datagridview Doesn't Show Data?

Oct 7, 2009

I have a user control that contains a search value text box a button, and a datagridview to display what the data adapter found. In the data set designer, I have an ODBC connection to a table, with two SQL queries defined FillByCustomerName(NAME), and FillByCustomerNumber(CUSTOMER_NUMBER). If I preview the data in the designer, I see the data expected. The datagridview doesn't show any data. The functions PopulateGridByName and PopulateGridByNumber do the work. I've tried adding a dgCustomer.show statement, The form that calls the user control has no codebehind code, and throws no errors.

Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
Try
Dim SearchValue As String = CreateSearchValue()

Importing Data To Excel?

Feb 19, 2010

I am trying to import data from a server and put it into an excel sheet. I have included (imported) the Microsfot.Office.Interop package into my program. I have been looking through the Object Browser to find the correct commands to add this imported data. Should the ListColumns.Add and Listrows.Add functions be used in this spot? I have started a code however, it was initially going to be used with human interaction. The new direction is to make it automated. The section of code I have written follows:

#Region " (Import Data) This function will import the PI Tag Names and desired Attributes into an Excel worksheet "
Private Sub Import()

[Code]...

After the nvs.Add("changer", 1) there are many more attributes that are going to be added to the excel file but I did not feel they needed to be shown here.
