Hi
Assuming you are using the windows control (didnt check the asp.net one as I am lazy)
The syntax would be:
datagrid.Rows[ROW].Cells[CELL].Style.ForeColor = ________________
Hope this is of use
Dan
***Sorry this is for the datagridview control - if you are working on an old application let me know and i will look into this. If you can though I suggest using the datagridview control as it is the .NET2.0 version of a datagrid

I would like to open a vb program I created using another program. The program I created is similar to the one I am currently using just with extra functions I needed that the OEM program did not provide.
I was wondering if there was a way that I could have the OEM program access my program so that I could operate my program from the OEM program.
|
|
|
|
|
Nope. The OEM app has to be rewritten to "access" your app and use the extra functions.
|
|
|
|
|
what about this concept.
making one of your vb program executable then when trying to access the vbprogram from another vbprogram. use
'with an onclik event
shell "vbprogram1.exe";

Well, the main way would be stored procs, if you can't do that, then you can use parameterised querys. Last resort is to do some string mashing to pass in your parameter, but that opens you to SQL injection attacks.

txtSearch.Text = strSearch
This sets your search string to an empty string, of course. It also means your db code is in your presentation layer, which means your app is poorly designed ( well, not designed at all, really ).
I suspect your main problem is that you're not putting '' around your search string.

This happened because the original poster deleted his question, thereby orphaning the replys he got. It's a known issue and won't be fixed until the next release of the CodeProject web site.

Yikes this is a mess. I am trying to follow through the Changing color of text... thread. Almost there

Hi,
I am using Visual Studio 2005's Visual Basic developer. I have a problem that i need to extract the unicode from a text file to my progam. And normal character have not a problem but when come to a certain extent of the unicode set, it prompt a error saying that it is invaild.
Here is my code:
OpenFileDialog1.ShowDialog()
Dim direct As String
direct = OpenFileDialog1.FileName
Dim fs As FileStream
fs = New FileStream(direct, FileMode.Open)
Dim sr As StreamReader
sr = New StreamReader(fs)
Dim n1 As Integer
Dim s1(100) As Char
Dim n2 As Integer
n2 = 0
While sr.Peek >= -1
n1 = sr.Read()
s1(n2) = Chr(n1)
n2 += 1
End While
my input is this unicode, §. So when it read from file to here, it prompt the error. So please help me...!
Thanks and Regards,
A person who don't whether he is a newbie or novice.

Wow - what a mess.
1 - why do you limit yourself to 100 characters, instead of using a List or something ?
2 - why do you read one character at a time ?
File.ReadAllText will read an entire file in one line of code.

Hi,
thanks for commenting my previous program. I know that it is really in a WOW mess.
I try you method but I still have the unicode conversion problem that I posted in the first thread.
I appreciate your help. I have shorten the whole program as follows:
OpenFileDialog1.ShowDialog()
Dim direct As String
direct = OpenFileDialog1.FileName
Dim str As String
Dim adder As Integer
Dim reader As Integer
reader = 0
adder = 0
str = File.ReadAllText(direct)
reader = str.Length
Do While (adder <> reader)
Try
ComboBox1.Items.Add(str.Chars(adder))
adder += 1
Catch ex As Exception
End Try
Loop
So please help mi from the unicode's ASCII index is 167 after conversion. It is simple when you type in the unicode in to the windows form but I try to retrieve from file. WoW, it is very different and difficult, so need you people out that who is experted in it to help me out...
Thanks and Regards,

What does the code look like that wrote the file?? Maybe it's not really Unicode where you think it is.
Or, there's another possilibity. Change the ReadAllText line to:
Imports System.Io
Imports System.Text
.
.
.
str = File.ReadAllText(direct, Encoding.Unicode)
|
|
|
|

Thanks alot. It works.. But need to manipulate the working of normal File.ReadAllText(direct) and File.ReadAllText(direct, Encoding.Unicode)...
thanks a lot once again

how do i make a array and fill the listview1.groups.addrange(arrayname) with the array?
i want to add groups this way so i can sort the array and add the groups name in the right order: A-Z
i dont have a lot experience with arrays.
thanks for your help!

If you don't know anything about arrays, I highly suggest picking up a book on VB.NET and going through it. Without this basic knowledge, you're going to find most projects impossible to do.
Dim groupNames(2) As String
groupNames(0) = "Group2"
groupNames(1) = "Group3"
groupNames(2) = "Group1"
Array.Sort(groupNames)
For Each groupName As String In groupNames
ListView1.Groups.Add(New ListViewGroup(groupName))
Next
I've kept this example very simple. There's another method for creating a ListViewGroup array, that can be used with AddRange, that uses an Array's ConvertAll method, but you have to supply a Converter delegate and method to do the conversion from String to a ListViewGroup object. But, if you don't know arrays, this litte topic will not make any sense at all...

hi thanks four your reply
I do understand how arrays work but i dont know witch type and how i script them.
the code does not work
my code:
Dim groupNames(2) As String<br />
groupNames(0) = "Group2"<br />
groupNames(1) = "Group3"<br />
groupNames(2) = "Group1"<br />
<br />
Array.Sort(groupNames)<br />
' ListView1.Groups.Add("Group1", "Group1")<br />
For Each groupName As String In groupNames<br />
ListView1.Groups.Add(New ListViewGroup(groupName))<br />
Next<br />
ListView1.Items.Add("Item1", 0).Group = ListView1.Groups("Group1")<br />
ListView1.Items.Add("Item2", 0).Group = ListView1.Groups("Group2")<br />
ListView1.Items.Add("Item3", 0).Group = ListView1.Groups("Group3")<br />
End Sub

Define "does not work". What DOES happen?? Do you get an error message??
Is your code running on Windows XP or above? Did you EnableVisualStyles in your project?
