i use below code to open CSV file with openfiledialog to datagridview1. So i can show my CSV file at datagridview1.my problem is thaif CSV file have 5-10 line, it works good. But if CSV file 1000 line, it doesnt open. I have a error message that "it more than 60 second and it get CPU and RAM so much. You should use something(I dont understand what it means so i wrote something)"
OpenFileDialog1.Filter = "CSV Dosyalarą (*.csv)|*.csv"
'OpenFileDialog1.InitialDirectory = initialDirectory
OpenFileDialog1.Title = "CSV Dosyasą Seiniz"

It seems like in order to use "TextFieldParser " you need to include the path of the file to be parsed. Is it possible to use OpenFileDialog1 and then choose a file? I keep getting error messages.

I am running a piece of code which takes 3 secs to process and it is triggered by the clicking on the OK button on the OpenFileDialog1 box.
Everything works fine except the OpenFileDialog1 remains visible during this 3 second time period and I would prefer it to immediately hide once I click on the OK button.
I have inserted me.refresh in various locations without success but I believe this is acting on the form itself.
Any thoughts on ow to allow the box to close / refresh before the processing
I am having a problem with the AutoUpgradeEnabled property on OpenFileDialog1 and SaveFileDialog1. When set to True and I call it, it works fine, but it takes 2-5 seconds to return the filename I just selected with the dialog. The Dialog box changes to a larger box than when it's set to False. If I leave the property set to False, everything works normally and the selected filename pops up immediately. What does this AutoUpgradeEnabled property mean and why does it take so long to work? (I experienced this problem with VS2005 and VS2010)

View 1 RepliesI'm using VB (visual studio) 2008. I'm trying to search a microsoft word file and select/copy text from it What i want to do
a. Search for a string/word in a text document(i.e "question)
b. When its found copy of text from that point to a point further down the document defined by a certain string ("a.")
c. after this is done it will continue to look for the next time the same string occurs (i.e. "question"") and continue as above?
I've figured out how to search for the word (question) but not managed to figure out the rest of it. Heres the code so far

I currently know how to click a button on the application and when I click it, it invokes the OpenFileDialog Event or Object. After It Opens the Open File Dialog, I am able to select only ONE file from a location on my computer. After I click that Single File on my computer, I press the Okay or Open Button on the Open File Dialog, and then it adds that items to my list Box, knows as PlayList_00 and PlayList_01.
Here's what I got so far.
Private Sub addBTN_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles addBTN.Click
OFD.InitialDirectory = "C:Movies"
OFD.ShowDialog()
PlayList_00.Items.Add(OFD.FileName)

I have a Comma Separated value file in .txt format... simply put, its a bunch of data delimited by commas and text qualifier is separated with ""For example:
"So and so","1234","Blah Blah", "Foo","Bar","","","",""
"foofoo","barbar","etc.."
Where ever there is a carriage return it signifies a new row and every comma separates a new column from another.My next step is to go into VB.net and create an array using these values and having the commas serve as the delimeter and somehow making the array into a table where the text files' format matches the array After that array has been created, I need to select only certain parts of that array and store the value into a variable for later use.... how to make the array and selecting the certain info out of it..

I have a form that needs to add user selected items to a listbox. But these selections are done outside the form itself. So in windows explorer, the form pops up and then the user keeps clicking on files and I want these file names to be added to the listbox. How can I do this? in my case, as soon as I click outside, obviously the form loses focus. How can I "listen" to mous clicks outside?
