Just curious: Do you have a hard reason why you need to use an array as opposed to an arraylist?

It would handle all the resizing issues for you and, if needed, you can always generate an array from the ArrayList using ToArray().

This statement:

dim req() as Requirements

only declares a reference to an array of type Requirements. It doesn't instantiate it.

You need to initialize the reference to an instance of an array of that type before you can start assigning values to it.

Hello there,

I am trying to perse a word document by reading the style property of each paragraphs. Here is what I have so far:

<br />
dim myDoc as new Document<br />
dim pp as Paragraph<br />
dim str as String<br />
<br />
myDoc = CType(GetObject("test.doc"), Document)<br />
for each kk in myDoc.Paragraphs<br />
  if Mid(kk.Style.ToString(),1,12) = "requirement" Then<br />
    str = kk.Range.Text<br />
    SaveData(str)<br />
  end if<br />
next kk<br />

"requirement" is a name of style I have created in the test document. In short how I can read the stylename for the paragraph? Can anyone please let me know what is wrong with this code.

I've created a PrintDocument and have used PrintPreviewDialog as I'm designing it to preview the document... The PrintPreviewDialog appears EXACTLY how I want it to print, but when I print the document it shifts every item on every page to the right. It seems to increase the left margin.

Any suggestions on where too look or what to do?

Thanks,
Andrew

Hi.. any one please help me on this

I have two web forms... AllEntries.aspx and Update.aspx

I am using ASP.NET with VB.NET
AllEntries.aspx has a datagrid in which all columns are bound and editing entry is also there.
What i need to do is , when i click on Edit for the particular entry, page will be redirected to Update.aspx page.

Update.aspx page is kind of form where all textboxes and dropdown lists are there. So when i click on edit i want all the fields to be filled up taking the data from the database. i m using SQL server 2000 as back-end

Can any1 help me on this as i am not able to get all the textboxes filled with the entries in databse for that particular userin the datagrid.

Do we need to inherit the datagrid control in Update class and use datagrid's functionality? Datagrid is in AllEntries.aspx and i want to use it in Update.aspx. If Yes, then how?

-Thanx a lot

Scanners manufacturers tend to ship an API with their hardware, that allows you to get some sort of event when a scan has taken place, so first port of call is to speak to the manufacturer of your scanner.

In order to help you with some code, you need to be more specific...there is no such thing as a generic "send message to a server computer" - you need to be more specific with your needs.

You will also find people much more receptive to giving you help if you have at least tried to write some code yourself.... very unlikely you'll get full working code on a forum.

you have a space at the beginning of the path - not sure if this was a typo or the cause of the exception!

No problem, but its weird because I tried to replicate the error by providing a File.Open command with a path beginning with a space and no error occured...maybe you're on .NET 2.0 and that is a new "feature".

Glad you got it sorted.

Is there any alternative for doevent

Sushmadm20-Apr-06 4:27

Hi all,

I have implemented Uploading and downloading data though serial communication. During the time of Uploading/Downloading there will be continuous exchange of data. Hence any other action on my GUI during Upload or Download operation will not be allowed (like Minimising/Maximising the form and Exitibng from the form).The GUI will hang untill the operation is complete. So to make the GUI flexible for the user i have used DoEvents in my program which will be called at some particular locations. This solved my problem. But i heard that using DoEvent may result in some problem. As the DoEvents performs all the events which are pending in the windows message queue, it may hang my application if there is an event which consumes lot of time.Please someone help me with solving this problem Frown | :(

Thanks in Advance,
Sushma

To keep the GUI responsive while executing a long-running task you should execute that task in its own thread.

This can be done manually, using the Thread class, using the ThreadPool (in .NET 1.x) or the BackgroundWorker (.NET 2.x)

Hi all,

I have created a small application that I need to put on a website for download. I want the application to run for free for 30 days after which time the user must contact us if they want to continue to use it. I don't want to have to deal with managing serial numbers for all machines that use the application. What is the best way to do this? Is it easy to code or is there a good third party tool that someone could recommend?

Thanks for any help.

I'm not sure how to do it with your approach but i did it by returning a table with a SQL UDF.
I don't think this approach is too friendly on the overhead, wont advise doing it with large amounts of data.

CREATE	FUNCTION udfReturnMyData(<br />
	@MyArg1 varchar(30),<br />
	@MyArg2 int)<br />
<br />
RETURNS @v TABLE (Column1 int, Column2 int, Column3 Varchar(10))<br />
AS<br />
BEGIN<br />
	<br />
	insert into @v (column1, column2, column3)<br />
	(SELECT	Column1, Column2, Column3 From MyTable Where MyCondition = True)<br />
<br />
	return<br />
END

I call this function from VB by doing a simple SELECT * FROM udfReturnMyData(MyArg1, MyArg2)
Hope it helps.
