Since the results have some fields as NULL, I want to display a zero "0" wherever the value is null. I saw a single line of code yesterday on the forum which does the job, I'm unable to find it now though.

My program parses chat room text. In the room there are smileys that get displayed. What I'm trying to do is parse out the image URL, download the image and put the smiley in the correct spot between the text of the message.I can do the parsing and downloading of the image into the datagridview but this only works of the column is set as an image column. Obviously due to the nature of the program I need to be able to put both text and images into the same cell. How can I do this?

how to do this for vb6 however i am using vb 2008 and the code for vb6 does not seem to work.
I have designed a form with a text box on it, and a command button underneath. The idea is to run this as a sort of stiky notes section.
I want the text box to read rich text into the textbox (C:\\stickynotes.rtf")
Then i have a command button underneath which i want to save the content of the rich text box to the rtf file (C:\\stickynotes.rtf). This is so that the user can edit and ammend information.
here is some code i have so far
Dim fileReader As System.IO.StreamReader
fileReader = My.Computer.FileSystem.OpenTextFileReader("C:\\stickynotes.rtf")
I am using VS2008. I have a table in which the jpg images are stored. I can retrieve the images from the table and display it in datagridview. But many images are of different sizes. So the cell height of the datagridview changes according to the image size. Is it possible to give a fixed cell size for the image column and also shrink the image to that cell height.

View 12 RepliesI have a datagridview bound to an Access datatable. It is nothing more than a one column list of chemicals. To allow the user to more easily navigate the list, if they press a letter it will jump to the first chemical alphabetically of that letter. If they keep tapping that same letter it will move down that list one by one. This all works fine. The problem is if you hold down the letter it will progress down the list but it doesn't show that progression. I want it to function much like if you hold down the down arrow key in a datable you'll see each successive cell be selected as it goes down the column.

I'm just wondering if it's possible to display a string in a integer column in a DataGridView? The reason I'm asking is that I have a column wich displays the place for each runner (it's a sports application). And if the runner is disqualified, it will display "DSQ" instead of the place.
Now, if I want to sort by clicking the column header, there's a problem if there are more than 10 runners. If there are like 12 runners, the sorting will be like this:

I am new to VB.Net, but I can tell you so far I love programming. That said, I'm building a tool basically to parse and display simple plain text log files. I'm hitting one stumbling block that really has me frustrated.
Other tools are able to load huge log files (500MB even) in a number of seconds. My tool, basically hangs loading a file that is maybe 5MB.
I'm using the MyString = StreamReader.ReadToEnd to read the contents into a string, and then RichTextBox1.Text = MyString to display the contents. That said, I really want to display the contents in a datagrid, but there has to be a better way of doing this?
How can I get my application to load larger files and display them faster? What am I doing wrong?
I am trying to make a calculator program. I would like the display(text box) to have a white background, with black font. So I set the "enabled" property of the textbox to "false"(because I want it to display, not receive input) and then choose the background colour to be white. In the form designer, the text colour is black, which is what I want.But when I start debugging, the text becomes the colour of the form. How can I make the font black?
