I've never had to zip programatically before, but I have had to unzip. I did it by creating and executing a batch file that ran an unzip program (the one I used was winRAR, but I'm sure winzip would have something similar) through parameters. I was able to pass parms that ran the program in a silent mode, but you could still see the dos screen flash for a moment. It wasn't a very pretty solution, but I only needed it to work for a one time thing. Perhaps the best place to start your search for more information is documentation on winzip or some other zipping program.

Hope this helps.

First you have to install wzcline (winzip add-on).

Const pathWinZip = "C:\...\Wzzip.exe"
Shell(pathWinZip & " C:\1\1.zip " & "C:\1\*.*", vbHide)

OR

'This is better because until the zip is not totally completed the program 'will not continue to the next statement.
'The only problem is that a prompt command window popup for a few second and 'close itself. I don't know how to hide it.
Const pathWinZip = "C:\...\Wzzip.exe"
Dim WSHShell As Object = CreateObject("Wscript.Shell")
WSHShell.exec(pathWinZip & " C:\1\1.zip " & "C:\1\*.*")
'waiting for zip end task...
WSHShell = Nothing

explanation: all the files that are located in C:\1\ will be zipped into C:\1\1.zip

Hope it helps

This code relies on the user having WinZip installed. Not good bet in my book. Using a library that's compiled into his own app removes that dependancy.

Is the Crystal Report on the same machine that holds the MS Access Database? If not, you could speed it up by putting them on the same machine.

Hello Pete,

If your report contains sub-report, please try to uncheck the checkbox "Re-import When Opening" in the "Subreport" tab page of Format Editor of the subreport.

You may also try to declare global object of report, when user first starts your application create a new thread and in this new thread fill data in your report but do not bind it to CrystalReport Viewer, when the user wants to view report on click of some button then bind this report to Viewer.

I hope this helps.

Regards,
James

Migration issue in VS 2005

Your code setup up the share, but doesn't do anything to set any permissions. Which version of the .NET Framework are you using?

Hi ,

I had a project in version 1.1 and I have
migrated it to 2.0 using visual studio .NET 2005 but its throwing the
following script error in IE 6.0 only while selecting any value in drop down.

'event' is null or not an object.

In firefox, it is working fine.

I used DOM Validations for firing client side validations. This error is firing even before the drop down's selected index changed function is called.

Can anyone please help me out to solve this. is there any property or
setting i have to make for 2003 project to work in 2005?

Is it a bug in VS.NET or is there anything settings to be made?

kindly do help me guys.

Vikram

Re: Anchor problem in VS2003

17-Sep-07 7:52

This is a question better asked in the ASP.NET library. It doesn't have anything to do with VB.NET.

No. ASP.NET 1.1 and ASP.NET 2.0 work very differently. These differences may be what's causing your problem, though I have little to no experience on the ASP.NET side.

Hi all,
Iam working on windows applicaiton in VS2003 and when iam putting anchor on a datagrid for example iam experiencing an unstability in width and heigh size of thew datagrid control.
Iam using a datagrid and when i put anchor on right, top and bottom i notice this issue. When i enter the design of the form again i need to adjust the width and height of the datagrid again. I find the width and height i fthe grid is bigger than the size of the form. I keep fixing it manullay and save. but when i enter the form design aagin i find it bigger. Iam faing this issue with button control also. I have a button with anchor top and right, the same issue happens when i enter the design later i cant see the button cause it takes a position out side the form.
Any help please it is really annoying.

If you haven't already, you may want to install Visual Studio .NET 2003 Service Pack 1[^] first.

this is a very simple way to do it (don't know if it will meet you expectations)

imports system.web.mail
...

Dim obj As SmtpMail ' Variable which will send the mail  
Dim Mailmsg As New MailMessage()
        obj.SmtpServer = "server:relay.skynet.be" 
        Mailmsg.To = "test@test.be" 'the email adress to send to
        Mailmsg.From = "\" & (sender) & "\ <" & (sendermail) & ">" '(sender) = the name to be displayed  || (sendermail) = a valid email adress from wich to send
        Mailmsg.BodyFormat = MailFormat.Text
        Mailmsg.Subject = "example"
        Mailmsg.Body = "example body"
        obj.Send(Mailmsg)

hope this helps

You have to add a reference System.Web and then add Imports System.Web.mail

like 'samerh' said
add a reference to system.web

you can find it on the '.net' tab or at 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Web.dll'

If my help was helpfull let me know, if not let me know why.
