Open CSV File With Openfiledialog1 To Datagridview1?
Feb 8, 2010
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)"
Here is code for selecting a file with the openfiledialog1 on button4_click
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click OpenFileDialog1.Title = "Please Select a File"
[Code]....
This code only can select files.. and not folders.... how do i make it select folders and not files?
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)
I watched a youtube video that showing me how to make multiselect work and it worked but its just one problem: It opens two times.

I've noticed that when you click on a web page in Windows Explorer, or open a file in general, and the default application to open it is internet explorer, ie opens and opens the file. However, when I tried this on my Web Browser it opened, but ignored the file and went on its usual routine. How can I get my Web Browser to open and open the file that was clicked on in explorer?
I saved a file with the extension .doc. I use the RichText to write and save the text. I did not set any encoding type when I saved it. When I tried to open the file in the Richtextbox again, I got all the formatting characters in the RTF file. How do I correct this? How do I open and re-open a .doc file in the Rich Text box control without the formatting showing up in the box with the document contents?

I created a simple form which has two tableadapters to a Access database. On the form I have a combobox that uses the Category TableAdapter and it populates on load fine. the other control is a DataGridView1 which is popluated by the Message Table Adapter based on which Category is selected. It does NOT populate on LOAD and thats my problem.
So the result I'm looking for is when you run the app and my first form loads it
A. Chooses the frist Category in the list (and it does that fine)
B. Populates the DataGridView1 based on the first Category (this is my problem) The DataGridView1 does Populate after I re-select the Category in the combobox1.
