Check your Database field which you R Trying to insert null value is not a required filed in that table, and it's not a *NOT NULL* Field.

Don't think Access'97 supports null strings.

VB6 and Access 97? Why are you developing in dead software/languages?

If the field is able to store NULL values, then you should also use the NULL in your insert statement:
insert into table (field, field, ...) values ('value', null, ...
|
|
|
|
|
In the design of the Access database table in question, ensure that the field is set to 'Allow Zero Length' and that it is not 'Required'.

Hello There,
I am developing a POS Application in vb.net and using Firebird 2.01 as Database. the only problem i have there is when the connections to Firebird increase...The Client Software starts FREEZING...mostly when updating a table [Stock]. Can anybody help.

Sounds like the software is freezing because of issues with the DB. Perhaps if you do your updates on another thread, or get a better database ?

Hi,
if you're using the VSTO you should find plenty of examples here and in MSDN. Just use e.g. "VSTO Sample" as keywords for your search. VSTO also has a template for COM Add-Ins.
Without VSTO it's a pretty complex issue.

Can someone explain how to develop a program that capture keystrokes and write them to a log file or text file? Like a keystroke monitor program.

Key loggers are always suspicious. You purpose of developing one might or might not be an honest one.
And, DO NOT CROSS POST.

It's always comforting to me that the people who want to write evil software, usually have no idea how to do it. Now, you may have a perfectly valid reason to write a keystroke logger, but that's not what people are going to think when you say it like that.

Unfortunately there will always be a few people who have both the desire and knowledge to do it. Luckily we're very unlikely to ever see any of them on CP.

Is it possible to show the calendar screen of a DateTimePicker control by clicking an image instead of clicking the control's downward triangle? I cannot find a property from the class for showing the calender screen. please help. Thanks.

AFAIK DateTimePicker exposes nothing about that down arrow. I can suggest either to go for a third party control or override OnPaint for the form and Paint an image on the down arrow.
|
|
|
|
|
Thank you,
I will solve the problem by writting the following
DateTimePicker1.Select()
SendKeys.Send("%{DOWN}")
If other suggestion, please advise
Eric H.

My bad. I thought you need to replace the down arrow of the datetimepicker with some other image. Your requirement seems different. Although, still not clear to me.
|
|
|
|
|
I will try to be clearer.
When you click the DateTimePicker control, at run time, the calendar is popping-up, doesn't it?
What I needed, instead of clicking the DateTimePicker control to get this popup window, is to click on a button and to get the same screen.
My target was to put on a button an icon of calendar and when the user click the button he will get the popup screen.
I hope it was clear now.

You can always build your own control/dialog, using MonthCalendar and pop that up in response to the button click.
