I am trying to check if a cell in a tablelayoutpanel contains anything and if it does; clear it.I tried tablelayoutpanel.removeat(1) but I need to check if there is actually anything in there, or else it throws an error.
View 2 RepliesI have used the XML serialization to save a single text and a picture in a XML file.However, I am confused on how to extend the concept further.I have a second Windows Form which has a TableLayoutPanel in which each cell has a Picture Box and a TextBox. The user has the option to set the number of rows and columns himself, so I do not know about the number of pictures that have to be saved in the XML file. Further, when the user pressed the load button, the same pictures have to come back to their original pictures boxes in the TableLayout.
How can I save the contents of the TableLayout in the XML file and retrieve them in their corresponding cells?

I want to remove the lines that start with "****" and keep deleting lines until i reach ";" I thought this would be simple but im missing something and I don't want to put this array into a listbox it is being writen to a text file.
I have an arraylist of strings, one of them looks like this:It's wet out here and [player id=3686163]Ripper[/player] knows it. That ball was like a bar of soap in a prison - nobody wanted to pick it up. Knock-on.
I need to remove the square brackets and the contents of them, to give:It's wet out here and Ripper knows it. That ball was like a bar of soap in a prison - nobody wanted to pick it up. Knock-on.
The contents of the square brackets are likely to change from string to string, and in some case I may have more that one player in that string.
What I want to do is remove the errortext once the data input is valid. I have a code that works perfectly fine. I had run it a number of times and its working properly the whole time. But after I restarted my computer, there seem to have been an error.

I am using the DataGridView in Visual Basic 2008 Express with an Access 2000 database.
What I'm trying to do is allow the user to click on the Row Header and capture the contents of the 4 cells in the row to 4 dfined variables. I know that I can capture each cell individually by using the CellContentClick event but this would require the user to click 4 times rather then just once.
clearing cell contents within a DataGridView?I have a column with a list of names and would like to be able to make the whole column blank.I can currently achieve this (not the greatest) by clicking on individual cells and doing this ..
DataGridView1.CurrentCell.Value = " "
But rather than doing this I would like to be able to do every cell in the column, all at once. I'll put the code behind a button, so it can all be achieved by a single click.
I have a DGV I am working on, and I have many columns.
For example I have Columns colIsDayOff (Checkbox), colStartTime(Time), colEndTime(Time)
What I need to do is if when my DGV loads the data if colIsDayOff is checked, then make the value of the Start and End time columns blank, invisible, or something.
I am trying to display a custom control in a datagridview cell so that I can show nicely formatted information.
I am quite comfortable with the use of datagridview control accepting a list of objects as its datasource. I am also comfortable with populating the cell contents in the cellformatting event.
So I am planning to, instead of using a normal textbox control, button control and linkedtext control in datagridview cell, display my own custom control which is good one for displaying some custom data like, name, address, telephone, photo and others. It would be a nice improvement in my application.
I am trying to display the contents from a datagrid into a textbox, there are two collums that I want to display. I can get one collum to display by using the following code.
txtCollumone.Text = DataGridView3.CurrentCell.Value
but I want to display (from the same row), collum two.
I am attempting to copy the value of the TimeStamp in cell A6 which has the NOW() formula into cell A5 Based on a change in Cell A4.

I am trying to create a code where I placed sets of numbers in an array.I'll use a masktextbox to have the user enter the numbers to match what's in the array. If the user enters the number, ex: social, and the data is correct (matches the numbers in the array), something happens if the number entered in the masktextbox does not match any of the number sets in an array then another thing happens.The masktextbox so far only validates format and gets number only, however, I want the number entered to match whats in the array.
View 1 RepliesI want to create a 2-high, 6-wide grid with labels in the top row and text boxes in the bottom row. Creating the six labels and the six text boxes is easy. Main Question: How do I stuff them into the TableLayoutPanel at the locations I want?I assume that I write the labels as I would any other label, and read and write the text boxes as I would any other text box.Secondary question: Why do all Microsoft's examples do stuff I never need to do, and never do the simple stuff I need to do?
