View 6 RepliesI am currently exporting from a DataGridView to Excel by looping through all the rows & columns in the DGV, which is very slow when you have a lot of rows. Here is the code I currently use:
For i = 0 To Me.DataGridView1.Rows.Count - 1
For j = 0 To Me.DataGridView1.Columns.Count - 1
xlWorkSheet.Cells(i + 2, j + 1) = Me.DataGridView1(j, i).Value.ToString().Trim
Next

Is it possible to export an entire row to excel, instead of having to do it one cell at a time? I'm just looking for ways to make the process faster.
Since i have a background on my progam it is very slow. You got a code to make it faster?

View 4 RepliesI have a function that I use quite a bit that I wrote more than 2 years ago. It works fine but recently I saw how it can use up a good deal of time under certain condition. Here's some code that uses the function SelectValue The function works so that if you had N which you plug into the function rising continuously while SelectLimit was set to 255 then SelectValue would match N until N reached 256. SelectValue would start to descend to 0 until it reached 0 and then it would again ascend to 255 and the process would repeat. So SelectValue(255, 255) would return 255 and SelectValue(256, 255) would return 254. SelectValue(257, 255) would return 253.
Option Strict On
Public Class Form1
Dim sw As Stopwatch
[code]....
The function works exactly as I want it to but if one of you knows a way to write this so that it will process faster then you can let me know. I get a result for processing time of 6.11 seconds on my computer for the above code.

View 6 RepliesI was just wondering if a computer would add two numbers together (positive) faster that comparing two numbers.
I was thinking that it would be comparison (best case) due to the fact that the 0th bits could be different right off the bat. Where as when adding, moving from bit 0 to N is mandatory for addition.
But then again a computer may add/compare differently than I am imagining.
I have a simple multithread application that stores updated data from a list of websites. After each thread gathers data, it then store the data into the same text file. I am now thinking of having each thread store the data directly into a arrayList, and after a certain amount of time past, store from the arrayList to the text file. Which situation would enable the application to complete its task faster?

Theonly thing I cannot figure out is how to use 1 picturebox and link the image to display to the radiobutton.
I have tried all kinds of queries on the internet and cannot locate the answer. There might be something with an Image.FromFile command I saw but that might have been from a previous version of VB and I could not get it to work in VB9.

I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.
I've got a form with parent-child setup. The parent displays name and other demographic info.The child displays multiple addresses, one row at a time. There can only be one primary address for a name and this is designated by a checkbox at the top of the child form.If the user wants to change the primary address to another address,then they find the other address and click on the checkbox.The form checks the other addresses and if one is found that is designated as primary,the user is warned that one already exists and prompts them to change it.
So for example, a name has 2 addresses, the 2nd being the primary address.The user wants to change the 1st address to be primary.They click on the Primary Address checkbox for the 1st address.A warning displays that there is already an address listed as primary.The user then answers the prompt to change the 1st address to the primary address.The checkbox for the 2nd address will be unchecked and the checkbox will be checked for the 1st address.My problem is getting the checkbox unchecked for the 2nd address.If I close the form and reopen, then the checkbox is unchecked.How do I refresh the checkbox for the 2nd address?Here is the code I'm using to find if an address has already been marked as primary:[code]......

View 5 RepliesI am trying to identify the value if a checkbox against a record in a datagrid.
I am trying this:
Dim eRow As Integer
eRow = dgv.CurrentRow.Index
TextBox1.Text = dgv.Item(6, eRow).Value
But I get nothing it works on other fields in the datagridview. The user will de-select records he does not want to authorise. When he has done this I want to update another table with the values that are selected(or True) on a button click event. There could be 100's of records so not sure if this is the best way to go about this.

View 4 RepliesMy DGV has MultiRowSelect = True
I have 4 things I am trying to overcome when loading the DGV and when clicking on a row.
1. When the DGV loads, the first row is Selected by default. I would prefer that it not be since that row may not be needed to be selected and mistakenly left selected.
2. Column(0) contains an UnBound CheckBox, when I click it, I want the row to be Selected
3. When I click on the DGV Row, I want the CheckBox to be marked either True or False depending on the state before the row click and the row selected or unselected.
4. Bypassing the need for Ctrl or Shift to select multiple rows.
