To get examples, type Barcode in the search field at the top of this page, if you can't find the answer there, chances are it can't be done.

How would you get a message box to have a "Get Help" button that will open a document in the folder "Help" within the folder that the application is stored when you press it?
Also, I would like a custom icon as well (in the same location as the VS logo in this error below.)
Similar to this one
http://www.littlecatdevelopment.com/blog/vberror.JPG[^]
How would you create a custom message box as a library class so i could use it over again?
Any help would be nice
In the end we're all just the same

You would just create a brand new form, design it any way you like, and use it. You can put it in a dll if you want to, but that seems overkill.

My DataTable has a VarChar field with no default value and it does not allow Nulls.
This DataTable is bound to my form using a BindingSource.
For some this reason when I do a BindingSource.EndEdit , that field is cleared, meaning the value the user entered into the textbox becomes cleared, and an exception is thrown stating that this field does not allow NULLS.
This makes absolutely NO sense, why would the EndEdit physically edit the value of one of my controls? And why change it to NULL if the field is required?

Hi all, I have a form in which I load a .rpt file, populate som values and then export it into a .PDF file. Something goes seriously wrong here thou.
All occurances of the letter t is replaced with ti or tt. All occurances of ti is being replaced
with tt. So for an example out of the file.
Should be Becomes after export to Adobe PDF

I dunno why it does this. Has anyone else been out for it or am I alone in this matter?
Below is the "export" part of the code
<br />
CrystalReportViewer1.ReportSource = rptDocument<br />
<br />
<br />
Me.rtStatus.AppendText("Exporting to PDF" & vbCrLf)<br />
Application.DoEvents()<br />
<br />
Dim CryRepExportoptions As New CrystalDecisions.Shared.ExportOptions<br />
Dim CryRepDestination As New CrystalDecisions.Shared.DiskFileDestinationOptions<br />
Dim CryRepTypeOptions As New CrystalDecisions.Shared.PdfRtfWordFormatOptions<br />
<br />
CryRepDestination.DiskFileName = IO.Path.GetDirectoryName(Reflection.Assembly.GetExecutingAssembly.Location) + "\PDFTemp\" & Ticket.ToString & ".pdf"<br />
CryRepExportoptions = rptDocument.ExportOptions<br />
<br />
With CryRepExportoptions<br />
.ExportDestinationType = ExportDestinationType.DiskFile<br />
.ExportFormatType = CrystalDecisions.Shared.ExportFormatType.PortableDocFormat<br />
.DestinationOptions = CryRepDestination<br />
.FormatOptions = CryRepTypeOptions<br />
End With<br />
<br />
rptDocument.Export()<br />
<br />
I'm completely clueless in this matter. Any help would be greatly appreciated.

hello,
i ve got a problem, where i have two asp pages say "A" and "B".
"A" and "B" are two differnet applications running on two different browsers on a same PC.
clicking a link on page "A" should check whether "B" is already running on that PC or not.
if yes then pass some parameter to page "B".
if no then create a new instance of page "B" in a new browser and pass parameters.
A help would be greatly appreciated.

Didn't you ask this using a different account the other day ?
You can't do it. A web browser cannot iterate over other browser instances that are running, it can't question them about where they are browsing. At least, not using javascript, AFAIK.

Probably you should look at opening a new window with a predefined name - this is all javascript:
var w = window.open("B" with params,"BWindow");
AFAIK, this will re-use the window with the same name if already open with the passed URL.
But remember that effectively, you are firing a new request to the server when you add the params.
Hope this helps.

That will obviously work, but I understood that he wants to find application B, no matter where it was previously opened from

Based on the above, I surmised that the apps(pages) are running on the same PC. Still, I might be wrong in my understanding.

Hello,
I have a datagridView and I have a text box, I would like the user to enter some letter that will narrow the search down. For example in they type s as the first letter, it will find all the words that begin with s in a column in the datagridview. Moreover, if they type st then it will narrow all the words even further.
I am using typed dataset and have it bound to the datagridview.
I have done this in order versions of visual studio by passing a query using the like keyword. But in 2005 using typed datasets and datagridView is there a more automated way to do this.
Many thanks for any suggestions,
Steve

' ''-------------------Selecting searchText
Private Sub txtSearchEname_KeyPress(ByVal sender As Object, ByVal e As
System.Windows.Forms.KeyPressEventArgs) Handles txtSearch2.KeyPress
Dim strSearch As String
Dim i As Integer
If txtSearch2.Text = "" Then
Exit Sub
End If
strSearch = txtSearch2.Text
If Asc(e.KeyChar()) = 13 Then
For i = 0 To DgvEmpList.RowCount - 1
If (UCase(Trim(DgvEmpList.Item(2, i).Value)) Like "*" & (UCase(Trim(strSearch)))
& "*") Then
DgvEmpList.Rows(rowSelected).Selected = False

End If

Hello,
Thanks a for your answer.
A better method is to use the bindingsource and set the filer. e.g.
<br />
BindingSource1.Filter = string.format("{0} LIKE '{1}%'",me.cboSearchText.Text,me.txtSearch.text)<br />
This should be in the text changed event of the text box.
Steve

Hi Priya,
There are 2 methods using the datarowview of the bindingsource row filter property.
<br />
dim drv as datarowview<br />
drv = directcast(me.grdMyDataGrid,datasource, datarowview)<br />
drv.rowfilter = string.format("{0} LIKE '{1}'%", cboSearch.text, txtsearch.text)<br />
There is also another method where you can use the datasource default view property, there you can also set a filter.
If you need any more help, just reply to this i will give you more sample code,
Steve

(VS.net 2003) I need help with an application that launches certain events when the user presses certain keys/key combinations.
The only thing I can't do in this program is determine what keys/key combinations were pressed and if the certain key was pressed than i want to launch a certain event.
For instance if ctrl + Alt + C were pressed than the program would catch the key combination pressed and then launch a corresponding event.
Any help would be much appreciated. Thankyou!

There are three events, KEyDown, KeyPress, and KEyUp. Your app will only get them if it has input focus. A system wide hook can give you any key press that occurs.

The header would contain both regular charaters and unicode characters (triangle sorting indicator) in this case.
