Hi
I am using the EditingControlShowing event and casting eventargs to a combobox object to get the combobox selectedindex. This works fine when i first select the combobox but before the dropdown.
How do i then trap combobox selectionchanged events?

Hi all
Though its great to have new features with every release, it sucks if Microsoft takes away old stuff that worked actually great.
I have a searchtextbox with a search button.
And what I want to build in is if someone enter something in the textbox and press enter it should hit the underlying code.
For this I need to use the textbox Keypress Event.
If you look at the code below, I get an error:
Event 'KeyPress' cannot be found
I have to use VB, its the company's policy.No Javascript
Private Sub SearchTxt_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles SearchTxt.KeyPress
If Asc(e.KeyChar) = Windows.Forms.Keys.Enter Then
GoButton.PerformClick()
End If
End Sub
Thank you for your time

Can't test it in 2008 at the moment but you can just use the 'keydown' event.
Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If e.KeyCode = Keys.Enter Then
gobutton.performclick()
End If
End Sub

Perhaps you should try to reinstall visual studio, because the KeyPress event has not been removed from vb.net / vs 2008 (I use it in several apps myself).
Or is your "searchtextbox" not a regular textbox?
My advice is free, and you may get what you paid for.

This is either an idiotic statement, or you're writing a website, in which case you should have asked in the ASP.NET forum, and in which case, it's always been the case that you can't handle a keypress event, or a keydown, or anything like that. It would, of course, be utterly retarded for a page to do postbacks every time you press a key.

I am displaying the structure members in a listbox. But i need to remove the commented structure members and then display the the other members in the listbox. how do i do that?

What on earth do you mean by commented structure members ? You can change the displaymember in the listbox any time you like.

Hey Christian,
i am getting this structure member from a C++ file.
for Ex
Struct{
char name[20];
int l_age;
double l_salary;
} Employee;
In this i need to remove int salary and display the rest of the item in the listbox. now i am using InStr to check for "l_" character to select the structure, but how do i avoid the commented members?

You can't remove anything from a struct. You can create a new struct that contains only the members you want, and can initialise itself from an instance of a C++ struct, but I fail to understand why you'd bother.

Hi,
I am not sure if this is the right location for the question but if not then apologies in advance.
We have a VB2005 web app that dynamically creates a report, renders it as a PDF and saves it to a local location on the server without displaying it to the user. We use rdlc files and the report designer in VS2005 NOT crystal reports. The web site uses ASP.NET 2, IIS7 and 2008. This web app works fine and is reliable. I would like to be able to create this same report and save it locally on the server via a web service call from a windows app. I have taken the code from the web page that performs the job now which does include a report viewer control and put it into a web service and when the local report object tries to add the report data source then it fails with a SOAP exception (null object reference).
I have provided a list of part of the code below. We use an xml file as the data source and load that into a dataset via LoadDDR call. CCA_DataTable1 exists in the local App_Code Folder.
ds4.WriteXml(xmlfile, XmlWriteMode.WriteSchema)
dp4.Dispose()
ds4.Dispose()
Dim rp1 As New Microsoft.Reporting.WebForms.LocalReport
Dim repdatsce = New ReportDataSource("CCA_DataTable1", LoadDDR(xmlfile))
"below is the line that fails with the null exception"
rp1.DataSources.Add(repdatsce)
rp1.ReportPath = "CCA1.rdlc"
etc etc
It may be that a local report requires a report viewer control on a page/form to operate correctly and therefore will not work via a web service (SOAP) call. I would be grateful for any suggestions anyone has to offer to overcome this problem - Thank You in advance.

I am facing a strange issue when sending a simple text mail with unicode characters.
This is the code which I am using
Set objMessage = CreateObject("CDO.Message")
objMessage.Subject = "another test"
objMessage.From = "sender@test.com"
objMessage.To = "to@test.com"
objMessage.TextBody = "मानस"
objMessage.Send
Till, this point everything looks fine but as soon as I try to specify the charset of the body, the bosy content get corrupted and strage charcters appear in the email.
objMessage.BodyPart.CharSet = "utf-8"
That is, when I add the above line of code it simply does not work.
You may try to reproduce this by copying code into a vbs file.
Anyone has a clue?

I am receiving an error from crystal reports that says i am missing parameters when i tell a report to print directly to a printer.
Here is the calling code.
Dim rdReport As CrystalDecisions.CrystalReports.Engine.ReportDocument
rdReport = PrintDocuments("Xbox Ticket")
'Main Report
rdReport.SetParameterValue("CustomerName", frm.cboCustomerName.Text.ToUpper)
rdReport.SetParameterValue("CustomerPhoneNumber", frm.lblPhoneNumber.Text.ToUpper)

First this app is an intranet WebForms app.
I have displayed bond data in a datalist with additional textboxes in the datalist grid for data entry. I'm actually looking for a better solution than the one that is currently implemented.
Currnetly: textbox1 is txtQty, textbox2 is txtRate, label1 is lblTotal and button1 is btnCompute. The user enters data in txtQty and txtRate click on btnCompute thus invoke datalist_ItemCommand and retrieve the txtQty & txtRate using the .FindCommand for the current row, then compute the lblTotal and move to the next row. This subroutine gets access to "byval e as System.Web.UI.WebControls.DatalistItemEventArgs" which makes the current row available and life is great, except the dataentry operator has to click the compute button.
I would like to get rid of the button and set up the app to use the OnTextChange Event of the textbox. this is a problem because it uses "byval e as System.EventArgs" for its argument and the current datalist row is not available.
Can anybody show me how to get the current row of the datalist for the textbox that triggered the OnTextChange event?
Thanks, Chuck

Hi there Vb community, im looking for help or an example for the following:
Im looking to create a program that starts up with user login, once users login they would be taken to the latest news etc. Using a tab control or something similar the user can click on mail/jobs specific to that user only.
If your slightly confused, i'd like something like this for employees.
Any help or advise would be great thanks,

Sounds more like a corporate Portal than a VB (windows) applicaiton.
Before you go and build something, take a look at Dot Net Nuke (DNN).
http://www.dotnetnuke.com/[^]
Take the time to learn about it and you will be amazed at what you get for free! 
I implemented it at my previous company and it works really well.

Hi if you are familiar with Visual basic then it's so easy to creat that kind of software .
At first your must to know all atribute . Make a design of data base
E-R diagram depand on your requrement.
First : you design the diagram and make relation with all entity (
Entity-Relationship Model )
Second : Make form depand on those table you made and relationship of model ( You must to make a table of user name and password and make relation with users )
Then it will be more easy.
If You want source code or if you want sample Please write would try to reply you as soon as possible

I've looked at several examples (not the database piece yet for capturing the "Yes" instances) and put together the code listed below. In a prior version of code also in the ItemSend Object the user is presented with the message box like I want and if they select "No" the E-Mail message is not sent.
However, when I tried to modify the code (see below) I get the Microsoft VB error:
"Run-time error '424' Object Required
Can someone help me correct my code statement and also let me know if I have the correct syntax for searching the body of the E-Mail message. I created a test E-Mail message with "Joe" in the body of the message. If I can't figure out the database piece, is the only option I have hard coding the names of all the restricted employees?
Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
Dim olMail As Outlook.MailItem
Set olMail = olapp.CreateItem(olMailItem)
Dim blnExecute As Boolean
If InStr(olMail.Body, "Joe") <> 0 Then
blnExecute = CBool(MsgBox("You are sending " & _
"or forwarding an E-Mail message from a " & _
"restricted employee, do you wish to " & _
"continue?", vbYesNo, "Rule Execution") = vbYes)
If blnExecute = True Then
'Eventually want some code to capture that
'the end-user chose to send the E-Mail
'message.
ElseIf blnExecute = False Then
Cancel = True 'this will cancel the send
End If
End If
Thanks for your help as always.

hi, im new-ish to vb
im currently pseudocoding a program for sorting some data. the data is pulled from file or database, then compared against some fields in another file or db, then put into an array. the initial data has 5 fields, the second has 8, and the result has 2 fields. at the moment its 400+ entries with 40-60 groups with 4-8 comparisons for each
what i am endlessly confused about is if a 5D array "appears" the same as a db table with 5 columns or if it more closely resembles a black hole (so i can visualise it a bit easier) and whether it would be easier to code 5 x 2D arrays for the data and another 8 x 2D for the tests
oh, and which method is more efficient
-N
note: i have completed the file>array bit and can compare two arrays
|

IMO a database table is a one-dimensional array holding rows; each row holds fields of different types, something an array isn't capable of in most languages.
In C#, C/C++, or VB.NET a row could be represented by a class or struct, where each field corresponds to one field of the datatable row.
Do not use multi-dimensional arrays if you don't really need them, and don't use parallel one-dimensional arrays either: use more structured data, as in an array of structs/classes.
