Yes I agree that VB6 is "officially' dead. And I have no less than 3 other programs that are written in VB.net 2005. But for this project I have to convert it to VB6 before I can more forward to .Net and I have it at least 90 percent converted but there are several places in this code that uses the scenario that I presented in my question. That is why I am asking for help.

I would think you will have to rewrite the query in Access to duplicate the results, I would guess that DSum is an Access specific function that is no longer supported by the later version of DOA.
And yes the forum is for VB and you are correct to ask the ? here, however it stikes me as invalid to move from 5 to 6 before moving to .net, a waste of resources. I just hope it is not so you can use the upgrade wizard to get the app into .net!

What kind of error message? Just saying you have an error message and not telling anyone what it says, really isn't going to have anyone help you at all.

I have textbox where I am showing the date and the format of this date is short date "01/01/2008".I have a variable called mDeliveryDate as date and I want to stroe the textbox date in Variable with the format "01-Jan-2008" for which I am using the following statement
mDeliveryDate = Format(txtdate.text,"dd-MMM-yyyy")
I am getting error something like conversion from string to date is invalid.
Any idea how to fix this.
Thanks in Advance

Defining mDeliveryDate as Date means it is stored in the system date format, not a string.
The format is done later.
DateTime.TryParse(txtdate.text, mDeliveryDate )<br />
Dim longDate As String = mDeliveryDate.ToString("dd-MMM-yyyy")
will give you "01-Jan-2008" in longDate. If it is an invalid date it will give you DateTime.MinValue (01-Jan-0001)
Hope this helps

i am using dotnet2005.i do my project in vb.net windows application.
i want to display amount as 12,34,567.00 in crystal report.
in my project,amount is displayed as 1,234,567.00 in crystal report.
displayed as 1,234,567.00 is wrong,displayed as 12,34,567.00 is correct.
so how to displayed as 12,34,567.00 in crystal report.
there is any options in crystalreport to displayed as 12,34,567.00.
no option means,can solve this problem using vb.net code.

First - this is a CR problem and so no VB-code will help you.
But you can provide format options for your fields in CR - try looking there (I think there might be a way).
If not you can create a formula-field in CR (it provides a own CR and even a Basic syntax) and format a number just like you would do it in plain VB.
If you don't manage this your last option is to use a character-field for the number and format it in VB before sending the data to the crystal report.

It looks like you want to format it for Indian currency.
I havn't looked into CR but I know VB does it automatically once you set the Culture setting.

i am using dotnet2005.i do my project in vb.net windows application.i want to add one year from selected date.the following code is
Private Sub FromDateTimePicker_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FromDateTimePicker.ValueChanged
ToDateTimePicker.Value = FromDateTimePicker.Value.AddYears(1).AddDays(-1)
End Sub
The above code is used to display as follow
for (ex)
using above code,if click date as 01/04/2008 in FromDateTimePicker means,then automatically displayed as 31/03/2009 in ToDateTimePicker.like this,if i click any date means,correctly worked.but if l click 29/02/2008 in FromDateTimePicker means,it must be automatically display as 27/02/2009 in ToDateTimePicker.But i want to display as 28/02/2009 in ToDateTimePicker.so in leap year above code is not working.how to solve this?

Use this condition to check whether the year is leap or not
If (DateTimePicker1.Value.Year Mod 4 =0) Then<br />
Else<br />
EndIf<br />
|
|
|
|
|
Note: That is not the complete condition to check for leap years, it only works for years close to now.
Experience is the sum of all the mistakes you have done.
|
|

|

add some code conditional on DateTime.IsLeapYear

Just subtract the day before you add the year:
ToDateTimePicker.Value = FromDateTimePicker.Value.AddDays(-1).AddYears(1)

In you are using 2005
In your datagridview choose edit columns, and change the type of column of the column you want to be a dropdown from datagridviewtextboxccolumn to datagridviewcombobox column and then you can bind the dropdown to any datasource

Hi,
I have this code that gives me an object reference not set to an instance object for variable objDI
when the code hits
outputfile = gserver.Outfolder & "\" & objDI.outputfolder
This is weird because the PDFDocs count is 1.
Please help.
<code>
For Each objDI In objSI.PDFDocs
outputFile = gServDef.OutFolder & "\" & objDI.OutputFile
If objDI.DocType = "HTM" Then
If Not PrintHTM(objDI.InputFile, outputFile, objSI.ToString) Then
LogPrintError(objSI, file)
Return False
End If
Else
If Not PrintOther(gServDef.InFolder & "\" & objDI.InputFile, outputFile, objSI.ToString) Then
LogPrintError(objSI, file)
Return False
End If
End If
Next
<\code>

You failed to specify what type of object objDI is, therefore you will not have access to its properties. If you add As PDFDoc after For Each objDI, or whatever type of object collection you are enumerating, this should work as you expect.
Clean code is the key to happiness.

|
|
|
|
I had actually declared the variable objDI at the top of the function
whch I did not include in the code snippet.
But I will try your idea anyway.

Hello everyone, I need help with some options.
I am creating a test app more as a proof of concept type deal. In the end, this project is likly going to moved to asp but thats later. Right now I have a set of classes that create themselves from a database. The program has to take the objects and put them into seperate groups, then compare them. Once an object is done, it is removed from the group.
This works fine when I am just comparing two objects, but I am stuck when it comes to finding a way to throw them into two or more groups, and compare each item in turn. At first I thought an array or linked list would work, but I am not sure what the performance would be when each array has over one hundred objects.
Is this the way to go, or is this a good time to break the books open and go through collection?

a few hundred objects in a List or Array won't bother any CPU 
If we are talking about several millions ...
If you want some high performant code then you will have to look hard at the problem.
For example if you want to sort a bunch of objects into groups there are two major approaches:
1.) you talke object by object, try finding out the right group and then put the object in the right bucket - for this approach nothing is wrong with List (if you are using .net 3.5 try the HashSet if not the Dictionary might be the most performant - access like)
2.) You start by putting all objects in one group and then going through and splitting if necessary - this is commonly solved with an additional object-field (just a number indicating the group).
As a example for this option: maybe you did some compiler-theory course (or read the dragonbook). Anyway you might know a situation where you are working with finite-state machines (WF anyone  - sometimes you are wondereing if there is a way to get the FSM "smaller" (i.e. fewer states - same results) - this can be done by an algorithm that first puts all states in one group and then uses some sophisticated test to split those groups - as a result you get a collection of groups you can transform into a new FSM with the same resluts....
You see: for the second approach you will have to know your problem very well!
