So, if the First item in the listbox contained "Http%$$" then how would I change that to "Http:" without affecting the rest of the text in the item

How can I change the value of one data grid view's cell? I am trying to change the displayed value of an integer (0-5) into one of my enumeration value.
i.e. the current cell displays 3 and I want to change the displayed 3 into the fourth value in my enumeration.
I have a program in which I am doing a sql select on two tables with an outer join. In one option of my search I need to show all items in both tables so some items in the row will come back with a null value. I am familiar with using the DefaultCellStyle.NullValue = which works great when replacing Null values with the same value.
I am in need of replacing the null value in column 0 with the value in column 10. I think I am close but have not had any luck researching this on my own. Here is what I have.
dgvInventory.Columns(0).DefaultCellStyle.NullValue = CStr(dgvInventory.Item(10, ???).Value) if I replace the ??? with any value I get that rows data but all null values become the same, what can I do to tell it to replace the current rows column 0 with the current rows column 10 if column 0 is null.
I am trying to find or search record from a datagridview so I could replace it with a new data from a textbox. I used the datasource.find() method the only problem is...If the my Table consist only of one Row, the find method replaces that one row everytime i insert a data. I just couldn't figure out how to datagridview works with if else statment.
View 2 RepliesI'm populating a datagridview from a database where all the data has had apostrophes and quotation marks stripped out and replaced with ASCII values; now I want to replace them back. Since the user can perform a variety of queries that are all displayed in the same table, any column might contain text fields.

I am trying to load a DataGridView with a XML file. I got that part pretty easily. But I am having an issue with changing a column to an image column and then converting the text string to the image. This is how my xml is laid out.

View 3 RepliesThe file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.

View 2 RepliesI have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")

My original example could be solved using other methods. This example is more representative of the actual problem:

I am trying to think of a regex replace to replace double quotes with nothing. Example:
hello("hi there") would become hello(hi there)

View 1 RepliesI have a datagridview with a combobox coloumn. A few items have veen added to it. (Say Furniture, Property etc.).I wish when I select Property, the column 2 of my current row should get text Property.Which event to be fired for this.

I have a datagridView(DGV) on one of my form.DGV contains a column of type DatagridViewComboboxColumn.I have another column of SrNo.
Consider Table1 to be the table from where my DatagridView is filled which contains following fields SrNo,Value1,Value2.
My requirement is i want to fill the values in my DatagridViewComboboxColumn from Table1.The DatagridViewComboboxColumn's combobox should contain values of columns Value1,Value2 of Table1.
Sample data of Table1
SrNo Value1 Value2
1 2 3
2 4 5
As data in datagridView is filled from Table1 the data of SrNo column of Table1 is also populated in one of the column of DGV.
Now my DatagridViewComboboxColumn combobox should contain the values of Value1 and Value2 of Respective SrNo.
Like Row one of my DGV has SrNo 1 as first value,so the Value1 and Value2 of SrNo 1 should be added to the row's DatagridViewComboboxColumn.
Select distinct Value1,Value2 From Table1 where SrNo=DGV.items(0,DGV.currentcell.rowIndex).value.H ope this Query willl make things more clear
I have a datagridview with three columns which is filled using Datareader. There is a DatagridViewComboboxcolumn in the datagridView.
I want this DatagridViewComboboxcolumn should also be filled using datareader.
how can i add items to DatagridViewComboboxcolumn using Datareader. Below is the code that i have tried.
Here dr is SqlDatareader
Datagridview.Rows.Add(dr("Column1").ToString, dr("Column2"),dr("DatagridViewComboboxcolumn "))
But when i add this way im getting error on the DatagridViewComboboxcolumn Column.
I have a DataGridView control with two columns:
colName
colAnnounceURL
I also have a ComboBox that I need to bind to the colAnnounceURL in the DataGridView. So everytime I add new rows to the DataGridView, the ComboBox will be updated with the items in colAnnounceURL.
I have tried the following to no avail:
cboAnnounceURL.DataSource = dgvTrackers
cboAnnounceURL.DisplayMember = "colName"
cboAnnounceURL.ValueMember = "colAnnounceURL"
The code does not cause a crash but does nothing.
Both controls are visible to the user. The idea is to have DataGridView act as AnnounceURLs manager and ComboBox to set the active AnnounceURL.

I have a datagridview i use to load alot of klients into a combobox. The values of the datagridview is a connection to a MySQL db.
What it's suppose to do, is to: When clicking the combobox, it should make a list from the datagridview, getting all the names from the klients.
My problem is that it gets dublicated, and will use to much memory at a moment.
I've tryed to check if the item it was about to add allready existed in the datagridview, if it was, it shoudn't add it again, however my code failed, and I'm having huge CPU and RAM useage when running this problem for more than 30mins.
My code:
Private Sub loadCustomers()
SQL = "SELECT * FROM kunder;"
Try
[Code].....
The code above is only checking for dublicated in the combobox, And I want the code to also check for dublicated items in the datagridview.
Or a way to clear the datagridview right after the items are inserted into the combobox?

I am trying to filter out all unwanted characters from a string. All I want in the string is letters A-Z, numbers 0-9 as well as comma (,) plus (+) and quotes (").I figured how to do the letters and numbers, but the 3 special characters are giving me a problem. I also tried with the Chr(34) equivelant for the " sign, but no luck, as and " or , messes up the way the code is read. Here�s what I have so far, but it only works for A-Z and 0-9:
STR = System.Text.RegularExpressions.Regex.Replace(STR, "[^A-Z, 0-9, Chr(43) ]", "")
How can I specify in my string that I want to replace occurrences of ALL characters and replace them with a specified character? Something like this:
'assuming currentWord is a string that contains any word
_myWord = CurrentWord.Replace("a-z,A-Z", "*")
