I am working on a 3 tier application. We have a UI, Remoteserver and a database server. The application is working fine till any error occurs on Tier 29remoteserver) or Tier 3(error raised by an Sp in database server). The error messages are not propagated from Remoteserver to UI, instead we get the error message "Server encountered an internal error. For more information, turn on customErrors in the server's .config file."
Please send me a solution to this as soon as possible.
Thank you in Advance.

Is it possible to set the DateTimePicker control to blanks or no value at run time? Thanks.
I found my answer. Doing a Google search returns amazing results.

Probably not.
But the standard way to do this is:
set CheckBox property to true, this will show checkbox alongwith dtpicker, u can check or uncheck to do so.

What did you type in to search? I am having the same issue and have only found controls that cost money. Is there an answer?

I have a program which reads a series of employee names and ID numbers into a dataset and then sets the datasource of a combobox to that dataset. Below is some of the logic:
.cbxEEName.DataSource = ds.Tables("EmpmastTbl")
.cbxEEName.ValueMember = dt.Columns("EmpID").ToString
.cbxEEName.DisplayMember = dt.Columns("FullName").ToString
.cbxEEName.Visible = True
Since the list of names include both active and terminated employees, is there a way to bold the names of an employee who is active, and leave terminated employees as a regular font?
Any ideas are appreciated?

I am writing a simple program to arrange data into a spreadsheet. Easy enough. However, when I store mult-selected items from a listbox, wingdings appear after each item.
I have a "for" loop that pulls each item out of the listbox. I need those items stored in a single cell. Each item is independent from one another. Therefore, I used VB's "new line" call, vbCrLf or vbNewLine. When I do this, it puts wingdings at the end of each entry within the cell. I have tried to trim the character off, but that did not work. Any suggestions would be much appreciated. Thanks.
For i = 0 To ListBox1.ListCount - 1
If ListBox1.Selected(i) Then
ws.Cells(iRow, 3).Value = ws.Cells(iRow, 3).Value + ListBox1.List(i) + vbCrLf
End If
Next
This loops through each selected item in the listbox and displays the data in a single cell.

Dizzie, Like I said in my original reply earlier on this board, the vbCrLf character that you're using is the cause of the 'wingdings'. I presume you want something like this in the cell...
value1 value2 value3
or
value1<br />
value2<br />
value3
Both can be achieved by this change to your code...
For i = 0 To ListBox1.ListCount - 1
If ListBox1.Selected(i) Then
ws.Cells(iRow, 3).Value = ws.Cells(iRow, 3).Value & ListBox1.List(i) & " " ' that is a single space
End If
Next
The latter format is obtained by also reducing the cell width and permitting the text to wrap within the cell (an Excel format setting).

Steve,
Thanks for the quick reply. I believe if I make the spacing great enough, it might just work. Thanks again.
P.S. I know this an odd question, but did you used to or do drive a Saturn? I remembering talking to an Excel expert named Steve and he helped with a previous project. He used to say how he loved Saturns. Just curious.

Steve,
I have one more question if you have the time. I have a multi-selectable listbox. The listbox is what I use to populate the cells in the worksheet. I would like to be able to have duplicates of the same entry to enter into the cells. For instance: If I have list1, list2, list3 and I want to display list1 TWICE within a single cell, what do you suggest? Thanks.
Dizzle

I'm a bit unsure why you want to put multiple entries in each cell in the first place, but I guess you have a good reason. I am assuming that you currently do not have any duplicate rows in the multi-select listbox but you'll be artificially (by some algorithm) duplicating them into the cell? Is this correct?
The trick is really to identify which list rows you need to duplicate and then simply double concatenate the value and store it as per the code I previously sent (i.e. cell.Value = listrowX.Text & " " & listrowX.Text) - I'm tired and that's not the correct syntax but I hope the meaning is clear.
If I have misunderstood anything please let me know.
...Steve

I developed one project in VB6 before 1.5 year and it is running successfully till now. Suddednly a strange problem is reported by client. The problem is, to display any report,
user need to select From and To dates provided by DTPicker control and based on two dates report shows data between selected dates, but report shows from date as selected and To date of system date(today). Means From date is working fine but To date is always system date irrespective of selection of any date from dtpicker.
I checked the code and i have not written any code to change selected date as system date. what can be the problem?
thanks.

1. this is a web application.
2. there are 2 pages. page1.aspx and page2.aspx
3. I'm using sql server.
I am using 1 table in the server to collect all the data. When the user logs in they are taken to the first page(page1.aspx) here they are asked to input some of the data. The application creates a new record with a unique identifier called form_id. The user inputs the data and is then taken to page2.aspx. Here the user is to update the new record(from page1.aspx) they just created but i can't seem to be able to tell the application to go to the database and retrieve the last record entered.

Hi,
many ways.
one is use output parameter in stored proc. and return latest id generated by page, get back id and pass it in querystring, from page2, get record by passing new id.
another way is use a query like use max function for id, but this might cause problem in multiuser environment.
Atul.

What's not working about it? Please be more specific in your postings so that we don't have to read your entire code to find out - that ultimately benefits us all 
I presume you do have a line similar to Do While Not rst.EOF to match the closing Loop statement? Good.
Be wary of compound or statements like this:
if isnull(rst("reportMonth"))= true or len(rst("reportMonth"))=0 then
because you may find that BOTH sides of the or may be evaluated before the result of the If is resolved. It could be that either the LHS or RHS of the or is throwing an exception?

Good morning to everyone!
I have created an Udp Class to handle UDP communication (using the UdpClient class provided by the Framework).
To correctly handle the receival of data I have created a new thread (this is also shown in the many examples found on the internet). My problem is: if I try to assign the data received to a textbox (for example) an exception is raised since the window (the textbox) was created in a different thread. This is not a big problem (the exception is raised only at design time and not at runtime) but I'd like to know if there is a way to avoid this problem.
Thank you!

Hi im fairly new to VB.NET or programming for that matter. I was wondering how I could pass data from one form to the other with additional data from a database.
Here's the case...I've a web app that displays various company department in which when i click on my view button it shows the machines that are assigned to them. Now here is my problem...every machine displayed on my datagrid has a detail link which i would hopefully like to show the details of the machine including serial number, date of purchase, supplier, product ID etc. Only...im not sure how to do it. Logically i think i would have to use a primary key ("Prodict ID") then use it as reference on what the other lbl boxes would display.
Could someone please give me a headstart on how to go about doing this. Thanx for all your help and suggestions!
Kampai!!!

Create the corresponding object variables in the second form,
pass as a parameter to that form before loading the form,
Perform the related operations on 'ON-LOAD' event

On-Load....oh Page_Load. Yeah I've figured then pass each label as a parameter. Wow thanx! This'l be one hell of a query...
