 I have a Application that has to start say every night at 9.
But I do not want to use windows scheduled tasks,
Do I have to use a Timer or is there another way.
Your input would be appriciated

Then your application is going to have to run continuously and perform its task at the time you set. A timer would allow it to wake up periodically to check the time.

You could also set the application into a loop that checks the time, if it is >= the time you specify it starts the job - when finished it flags it as done for the day. If the job is not running then it Thread.Sleep(x); and loops around again. However, if the application is sleeping it does not respond to the system so if you set x to be too long and shutdown your PC you may get an "application is not responding" error message.
Does this help?
Do you want to know more?

In addition to what Colin said, when he mentioned that your app has to run continuously, that means that a user has to be logged in and running your app 24x7. Are you sure this is what you want? Or are you considering converting your application to a service?

Thanx Dave
Yes that sounds good how do you convert your application to a service

I am linking all of the columns of a database table to a dataset, binding the table to a datagrid, and using simple binding to bind individual fields to text boxes. However, in the datagrid, I would like to only display a small subset of the columns in the record so that a user can recognize and select the desired record. I don't see a convenient way to do this. The DataView appears to require display of all of the table's columns. Any suggestions?

The DEFAULT DataView will generate all columns. Create your own DataView using only the columns you want (why do you think they call it a VIEW?), then Bind the DataGrid to that.
Creating a DataView[^] (.NET Developers Guide) Pay particular attention to the links at the bottom of the page.

You were right. Thanks. It was right under my nose all the time.

You should charge into dataset ONLY the lines and columns of the database table you really need, in this way it should works fine. To do it you only need to filter them using a SQL query. I mean you shouldn't charge dataset directly from database, you should charge dataset using a SQL query, in this way you'll see into Datagrid only the lines and columns you need.
I hope this help you.

Using VB.NET and an Access DB
How do I get from text to time that is recognized by .NET?
I am currently using the Masked Edit Control from VB.6 which I added to my toolbox. I have one Masked Edit Control for date, and am able to get the correct date. I have another control for time and no matter what I enter, it comes back as 1/1/2001.
For maskDate: format property is: dddddd, mask property is: ##/##/##
for maskTime: format property is: hh:mm, mask property is: ##:##
Dim dtmTime As Date<br />
Dim dtmDate As Date<br />
<br />
Dim drTime As ds5TimeDate.TimeTblRow<br />
drTime = Ds5TimeDate1.TimeTbl.NewTimeTblRow<br />
<br />
drTime.EventID = txtEventID.Text<br />
dtmDate = maskDate.FormattedText<br />
dtmTime = maskTime.FormattedText<br />
drTime._Date = dtmDate<br />
drTime.Time = dtmTime<br />
<br />
Ds5TimeDate1.TimeTbl.AddTimeTblRow(drTime)

Are you looking for DateTime.Parse()[^]?

Thanks, Dave,
But that seems to be about taking DateTime and manipulating it to get the string values desired. I want to go the other way, from string to DataTime.
On further investigation, it looks like VB is accepting the user input as LongTime (#10:00:00 AM#). The problem seems to be in updating the data source, the database in Access.
Anyone know how to turn the LongTime into 24-hour clock time?

If that were the case, the method would be called .ToString(). DateTime.Parse() takes a string, and optionally, a format provider for some guidance, and returns a .NET DateTime object with the numerical version of the date and time.
If the user is entering date and time seperately, you can combine them and submit the new date/time string to the Parse method:
dtmDate = maskDate.FormattedText
dtmTime = maskTime.FormattedText
Dim myDateTime As DateTime = DateTime.Parse( dtmDate & " " & dtmTime )
The .Parse() method assumes that the full date and time are provided in the current culture, which on default US machines is "mm/dd/yyyy hh:mm:ss". If any information is missing, the default action is to replace the missing information with the current date/time info.

Hello,
I have just finished writing a simple program that consists of 1 form, 2 embedded icons, and 1 notify icon. When I go into task manager, it says that it is taking up 21, 288 KB (21 MB) of memory.
How can I decrease the size of the memory "footprint" that my application puts on the computer? Or is it a limitation due to the .Net Framework?
Any suggestions or help will be appreciated,

Everyone new to the .NET Framework see's this and freeks out. It's normal! You don't (and CAN'T) do anything about it.
If you minimize the app and restore it, you'll see that your application seemingly dumps alot of this memory. In reality, it's not. What's going on is that you've got the weight of the .NET Framework under your application. When you minimize your app, alot of your code and data (whether it's part of your app or part of the Framework) gets swapped out to disk and no longer resides in physical RAM. When you restore the app, only the code and data that's needed immediately gets swapped back to RAM. As you use your application, more data and code is swapped back and forth to the pagefile as needed.
If the Garbage Collector sees that there is plenty of RAM to run your application, it might not swap this stuff out and free up RAM. Why waste the time, if it's really not necessary? Only when RAM starts to run low will the garbage collector be more aggressive swapping code and data out to disk and cleaning up objects that aren't in use any more.
Don't panic! Just let the Garbage Collector do it's job!

Thanks for the quick response. I originally thought it was due to my application.

Hi everyone,
I'm trying to find out if there is a way to apply Microsoft's Word formatting features to a textbox in .NET and be able to save and the retrieve the field to SQL server without loosing any of the formatting set. Does anyone know if this is possible? I would appreciate any comments or suggestions. Thanks so much!
Tasha

No, the TextBox doesn't support any formatting. The RichTextBox does, but on a much smaller scale than Word's formatting capabilities. Since the RTF formatting codes are in-line with the text, all you have to do to save everything is get the RichTextBox.Rtf, which returns a String, and save that to your database.

hi,
in vb.net i have a form which contains 2 buttons and some text fields. the user may enter the data in text fileds in the following format.
ex. "have a #nice# day". some of the words may be prefixed and suffixed with the # symbol. now when user presses the first button i want to store these data(dataset) to the rtf or text file.
when the user presses the 2nd button, i want to open the same text or rtf file and then i want to format the file in such a way that. all the #(hash) delimited words should be italisized and the file has to be save.
so anyone pls. help me.
thanks in advance
thiru.

Help you with what? So far, you haven't asked a question we can answer. You'll have to be specific about what part of your application you need help with and what the problem is.

I need code for two buttons. to save the tab delimited file in the file. and when i press the 2nd button to italisize the # delimited text in the file.
thank u,
thiru

Ok. There is nothing "tab delimited" about your initial post.
All your doing is saving the Text to a file. If your using a RichTextBox control, all you need is the .LoadFile and .SaveFile methods to do this for you.
The the second part, you have to scan the text to find the first occurance of a '#' character. Save that position. Continue scanning until you find the next '#". This will give you enough information to set the .SelectStart and .SelectLegth properties of the RichTextBox, then use the .SelectionFont property to change the font to italics. An example of which is found here[^] on MSDN.
Why does this smell like homework?
