View 1 RepliesDataGridView To Excel File?
Aug 21, 2010So I'm working on this project. I got around 60 images or so which I need to OCR, then I'll be inputting that data into my program which formats it and inputs it within this DataGridView. Now, I need the same data to be exported into an excel file. I saw several tutorials online but none of them are current (for VB 2008 or 2010). Either that, or they're not for VB.NET Windows Form Application. [I'm using VS 2010]
I'm fairly new to Datagridview as well. Just learnt how to add data to datagridview using this tutorial:
http:vb.net-inform...ridview_add.htm I was hoping you could help me out with where to start once I get my data all set up in the datagridview?

Loading Datagridview From File
May 3, 2010I've written the following sub to load a comma delimited file into my datagrid view but it's hanging up when it attempts to load the first two values into the cells of the datagridview. I think it's having trouble adding the cells to the datagrid. I have tried writting them directly using the .text of the specific row and cell but when I incremented to the next row it hung up because the row didn't exist (I think).

Loading XML File Into DataGridView?
Jun 9, 2011I generate my xml into "variable string str" by using "dataset.GetXml" and then I write the "xml which is contained in variable str" into "file.xml" by using sFile.WriteLine(str) while 'sFile' is a stream reader"My reason for using 'writeline' instead of 'dataset.WriteXml' because I need to encrypt the 'xml stored in 'str' before I store it into file.xml.I got everything fine for the encrypted result, and so does the decrypted result as well.Here's the decrypted result of my file.xml below (I have checked it the xml value which in str before encryption and which in decrypted file.xml. They are all match well)Here is my plain xml value before it got encrypted or decrypted which I stored it in variable str by using GetXml. I don't know for sure but my xml value doesn't contain declaration "<?xml version="1.0" encoding="utf-8" standalone="yes" ?>" like common xml used to have.All the xml file which I got from GetXml is just like below (No declaration like <?xml version="1.0" encoding="utf-8" bla ?>) Book 1 2010-09-22T14:43:00.0000000+07:00
And since I think it may not cause any problem then I keep coding and decrypt it which is going well and the decrypted result is perfectly same ofcourse.My problem is, when I try to make my xml value show in Data GridView by using the code below, and run the debug, it prompt an error said "could not find the file c:laFile.xml ".
ds = New DataSet
path = System.IO.Path.GetFullPath(strFileToDecrypt)

Mar 5, 2012Is it possible to use a datagridview with a text file? I'm guessing I can't just link it directly like I can with a SQL or access DB. But it has the option to manually add column headings so I'm guessing there may be some way of filling it in manually - like an array or something...?

DataGridView - Loading Each Table Of XML File?
Nov 9, 2010I am facing a "weird" problem with the DataGridView. In fact, I have a function, that loads each table of an xml file into a datagridview (27 tables all with same structure except one called Listes). In the datagridview I have a combobox column to select "type" (it's the 3rd Column, so it's index is 2 normally). The problem is that when I call the function loaddata for the first time, all work perfectly ! If I call it for a second time, to reload the data, I get an error of cast! I verified and it seems that first time I call the function the column that contains the combobox is column(2), but when I run it again automatically the indexes of the columns are changing and am getting the error, because the column that contains the combobox is becoming column (3) and that explains the cast error because the column'(2) is not anymore the combobox so the cast will fail ! What I can't understand is why it's reordering that way my columns automatically ?

oData = New DataSet
