Add to a source? Source of what?
Keep what as safe as possible? If you're talking about files, trying checking into the security features of NTFS.

DatePicker default value

I have several date fields in a database I am displaying. Some of the fields do not have a date value yet (they are set to null), but I would like to use the datepicker to put data into them. The problem is that fields that don't have a date in them from the database are filled in with the current date. If the user saves the record the current date will be saved to all the fields that should be blank (null).

Is there a way to display (or not to display) the datepicker field without a date in it?

Hi,
I am re-writing an application that used access as the backend.
I am using t-sql.
I have a query with this line, and I would just like to know the best way to convert it to sql.

CCur(Format(DSum("[Amount]","Line_Item_Payments","ChargeID=" & [Charges].[ID] & " AND Type =" & 4),"#,##0.00;;;0.00")) AS PC

Basically it looks in Line_Item_Payments for every charge in Charges and totals it by type.

I have been working with this query for a bit and have been unable to have workable results come from it.

Please help,

Slow performance

I have created a project of approx. 4400 lines of code (I used the project line counter to check it Poke tongue | ;-P

)

It looks great, but it is slow when I first click on a button in my program, to logon a user on a computer. (I created a cyber cafe management program)
I also created a sample of this project in C# and it seems faster there.

Is it possible that VB.NET delivers slower code than C#?
I know it's not possible in theory since it's all IL, but still...

Hi again,

When I stick the AxMsFlexgrid1 on to my form and when I run it, It just displays the form witout the datas in it,
If I remove it then all the datas appear on the form.

Like I am populating my combobox1 from the data set.
When I have the flex grid on my form the combox comes up empty.

But if I remove the Flex grid the combobox is populated from the data set.

What am I missing?

Tnx

Hi all,

Can some one help me as to why I am getting this error mssg?
@ da.SelectCommand.CommandText = "select orig,ordno,name,chkno,blno,state,adr1,orddt,txble,txcrt from cshhdrpf where orig = " & arr(1) & "and ordno = " & arr(2)

Error Mssg:
Additional Information: Index was outside the bounds of the array.

Dim arr As array
arr = Split(cmb1.Text, " - ")

Dim da As New OleDbDataAdapter()
Dim ds As New Data.DataTable()

da.SelectCommand = New OleDbCommand()
da.SelectCommand.Connection = conn

da.SelectCommand.CommandText = "select * from Test1 where orig = " & arr(1) & "and ordno = " & arr(2)
da.SelectCommand.CommandType = CommandType.Text

Tnx

Just like the error message says... The index 1 or 2 doesn't exist in your arr array.
You're either not splitting your cmb1.Text text with the correct splitter or you're not getting the result you expect. Try stepping through the code and see what arr = Split(cmb1.Text, " - ") is actually returning.

Hi,

I want to learn VB, but do not have access to Visual Basic, nor the funds to get hold of the s/w. I would be grateful if anyone could suggest a free software similar to the M$ version.

Downloading is not a problem. Hope to listen from you soon.

how can convert textbox value to double?

<br />
Convert.ToDouble(yourTextBox.Text);<br />

Remember to catch exceptions as this function will throw one if it the text cannot be converted.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
