These boards are for answering questions to do with programming. Your best bet for something like this is a site like Rentacoder. You can get stuff written there pretty cheap. Of course, it will be crap, but it will probably work, so long as you never want to change it.

Hi everyone
I have a grid in a Windows Application that I want to format. I have read messages and followed links so I can group my records and colour certain cells eg subgroup headings in blue (by overloading the datagridtextcolumn class)
However, I have two levels of grouping and I would like to format the more important group header as bold.
I can format the entire grid as bold, but just want the text of a few cells.
Could someone point me in the right direction?
Thanks
Marg

i have followed your question and by coincidence am working on a project where i have to differenciate the fields in a datagrid by coloring the particular cells depending upon the value.
i have tried a hard to do that but i was unsuccessful.
i think that u have a solution for my problem
so please give me one solution and am working for ur query and i will get back with a solution soon.
thanks

Hi Asif
You write a class to inherit from the usual column:
Public Class DataGridColoredTextBoxColumn<br />
Inherits DataGridTextBoxColumn<br />
<br />
Public Sub New()<br />
End Sub<br />
<br />
Protected Overloads Overrides Sub Paint(ByVal g As Graphics, ByVal bounds As Rectangle, ByVal source As CurrencyManager, ByVal rowNum As Integer, ByVal backBrush As Brush, ByVal foreBrush As Brush, ByVal alignToRight As Boolean)<br />
Dim strText As String<br />
Try<br />
Dim o As Object<br />
o = Me.GetColumnValueAtRow(source, rowNum)<br />
If (Not (o) Is Nothing) Then<br />
strText = CType(o, String)<br />
If strText.IndexOf("MyText") >= 0 Then<br />
backBrush = New SolidBrush(Color.White)<br />
foreBrush = New SolidBrush(Color.RoyalBlue)<br />
End If<br />
End If<br />
Catch ex As Exception<br />
<br />
Finally<br />
' call the base class gets called with the changed brushes <br />
MyBase.Paint(g, bounds, source, rowNum, backBrush, foreBrush, alignToRight)<br />
End Try<br />
End Sub<br />
End Class
I set the table and column styles through the properties window rather than code
Then, in the Windows form generated code, modify the column's class:
Friend WithEvents colCueDescription As CCP.DataGridColoredTextBoxColumn<br />
Me.colCueDescription = New CCP.DataGridColoredTextBoxColumn()
I think that was all - it was a little while ago. Let me know

To clarify that a bit - CCP is my project name

I have a gridview on my web page that uses an xml document (dataset) as it's data source. The xml dataset has two columns that I need to divide to get a single column for display on the web page. Does anyone know how I can do this with a template column? For example here is a snippet of the html:
<%# Bind("AnswerSeconds15")%>'>
What I want to do is something like this (although this does not work):
<%# Bind("AnswerSeconds15") / ("NumCalls15")%>
Thanks!

Hi all.
Im trying to popup a menu from a seperate process.
The following code can click a menu, but it doesnt affect menus with subitems, which i think is kinda weird. There must be another way.
Any ideas?
<br />
SendMessage(MenusParentWindowHandle,WM_COMMAND,MenusID,IndexOfTheSelectedMenu), Nothing)<br />
PS. I changed all the var names for easy readin.

whoops, MenusID = MenusParentID

|

Are you calling Api?
If yes then you had called findwindow api ya?
then
it's simple
call another API
Findwindowex
|
|
|
|
|
The FindWindowEx function retrieves a handle to a window whose class name and window name match the specified strings. The function searches child windows, beginning with the one following the specified child window. This function does not perform a case-sensitive search.
What i want to do is something entirely different.
Nice try though.

Hi. I'm a relatively new programmer to VB .NET so have a few stupid questions.
On validating user inputs into textboxes and such, is there a way to validate or restrict input to number or alphanumeric only? The few instructions I found seems to require creation of custom codes to do so. I'm getting frustrated by this atm. One workaround that I did was:
dim currentstring as string
KeyDown event
if the key pressed was a number (or backspace), then don't do anything
else set a flag to true
end if
TextChanged event
if flag is true then restore original currentstring
else currentstring = txt.Text
end if
flag = false
So in essence, if a user presses any other key aside from backspace and numbers, it restores the string in the textbox to the last successful string input (currentstring).
Then another question is whether I can retrieve the source of a webpage without the use of ASP. The idea of the program is to be able to get a word count of a webpage just by entering the URL.
Thanks for any help with these dilemmas.

There lots of way of doing it.
The more appropriate (in terms of OOP) is to write a class (i.e. NumericTextBox) that inherits from TextBox and adds the functionality you require.
But if you look around there are tons of pre built classes for that.
About retrieving web pages you don't need any ASP. Just have a look at the .NET FW documentation and you'll see that there are classes ready to be used for that. Thay may differ from 1.x to 2.x. Try to use one of the WebRequest derivated classes.

I don't understand this one...
Almost everything works except the Update on the grid: Delete, Cancel, Edit*
If I take the Load_Grid out of m_dgIDs.EditCommand--I have to click the Edit link twice for it to turn into a textbox that I can edit, but the original content is not there.
If I leave the Load_Grid in the EditCommand, the textbox will appear immediately with the cell's content and I can edit it. HOWEVER, the grid no longer appears to be bound and this line blows up:
Dim id As Integer = CType(e.Item.Cells(0).Text, Integer)
e.Item.Cells(0).Text is = "" or nothing
I tried to keep this code to a MIMIMUM because I know it is a lot to ask of forum members, but if someone has the time, I would appreciate any thoughts on the subject.
Thanks - A Lot.

Yeah, I am not sure what the "real" answer was to this. I threw it all away, used the MS example from help--then, added my code back in. I could post it upon request.
Thanks Anyway.

I have a situation where I have standard form class that I created. It inherits from System.Windows.Forms.Form as a public class. The only thing added to this class is a series of variables for passing data to these forms. There are no functions or overrides in the class.
I then create a FRIEND form that inherits this class. I put a textbox on the form and I can't use CTRL-V. In fact, I trapped the keydown events and if I do 'V', I get a keycode, if I do CTRL-SHIFT-V, I get a keycode, but if I just do CTRL-V, I don't even get a keycode (it never throws the keydown event at all.) And it won't paste anything into the control.
If I change the form to inherit the System.Windows.Forms.Form directly, it traps fine and pastes the text from the clipboard into the control.
Any ideas as to what would cause this to happen?

I am trying to figure out how to send data and my customer to my banks web site to enroll for paying their bills online.
The post string that I am suppose to use is:
https://banks_web_site.com/enroll?id=12345&name=Customer&accountid=98765&backurl=https://my_web_site.com/return.aspx
The bank will return to me the following info and my customer (so they can continue the payment process) via https://my_web_site.com/return.aspx?return=0&enroll_id=765431
I'm having trouble trying to get this to work, any help would be appreciated.
Another thing that has me stumped is if I do what the bank calls a payment search, I send to them with no return url:
https://banks_web_site.com/pay_search?id=12345&&enroll_id=765432&days=2
They will return the following:
0:::
7777:1:1123123123:VISA:987554
8888:1:1231238744:AMEX:876454
Unlike the first example, the returned info is not qualified by a query string name. How do you receive this data ?
|
|
|
|
|
Response.Redirect("https://banks_web_site.com/enroll?id=12345&name=Customer&accountid=98765&backurl=https://my_web_site.com/return.aspx")

Hi Again,
Request.QueryString should help with your other problem.
Can you keep the questions to the forum, rather than Emailing me directly please?
PS: All of this can be found in MSDN if you have a hunt around. You may find it quicker that posting because you will be able to find it as required.
Thanks,
L

I did look in MSDN and it showed using the request.query.string without any parameters and the output as being unparsed. But what they don't show and I don't understand is how I get the unparsed data into a variable that I can parse. The data that I will be receiving does not have any parameter names just data.
Thanks

Ok, try the following code, then call the page with a string appended to the url after a question mark. For example "http://LocalHost/TestWebSite/WebForm1.aspx?ARandomStringThatIAddedToTheURL"
Dim sQueryString As String = ""
For index As Integer = 0 To (Request.QueryString.Count - 1)
sQueryString &= Request.QueryString(index) & "<BR>"
Next
Response.Write("Query String: <BR><BR>" & sQueryString)

Hello to all,
I use this method to run rwrun60
Public Sub ExecuteReport(ByVal ProcessPath As String)
Dim objProcess As System.Diagnostics.Process
Try
objProcess = New System.Diagnostics.Process
objProcess.StartInfo.FileName = ProcessPath
objProcess.StartInfo.WindowStyle = ProcessWindowStyle.Normal
objProcess.Start()
'Wait until the process passes back an exit code
objProcess.WaitForExit()
'Free resources associated with this process
objProcess.Close()
Catch
MessageBox.Show("Could not start process " & ProcessPath, "Error")
End Try
End Sub
if i try the ProcessPath string like for example "notepad.exe"
everything works, but if i use rwrun60....
ProcessPath = "rwrun60 report=c:\PathToReports userid=AccessInfo paramform=no destype=FILE DESNAME=c:\Temp\ReportName.PDF DESFORMAT=PDF P_FORMATO=PDF batch=YES"
gives an exception... file not found !?
if i run on Dos shell works fine.
How can i know what is the problem?
Thanks for your time
The string

This is because your command line arguments must be seperated from your executable. You might also have to specify the full path to the .EXE
ProcessPath = "C:\whatever\path\to\exe\rwrun60"
ProcessArgs = "report=c:\PathToReports userid=AccessInfo paramform=no destype=FILE DESNAME=c:\Temp\ReportName.PDF DESFORMAT=PDF P_FORMATO=PDF batch=YES"
.
.
.
objProcess = New Process
With objProcess.StartInfo
.FileName = ProcessPath
.Arguments = ProcessArgs
.WindowStyle = ProcessWindowStyle.Normal
End With
objProcess.Start()
