You can also subtract dates:
If (RetrievedDate.Subtract(Now).TotalHours >= 1) Then
End If

Hi, dear all,
I have an existing VB6 project installed in my computer, I have its source codes. Now I will create another project based on it.
The strange thing is that there is a reference which is always pointed to the previous project, all others are ok after modification, only this one doesn't work. I open the .vbp file, modify the path mannually, save it. but when I open the project, it still points to previous project path, I use browse button in reference dialog to relocate it, it still not change.
What should I do? If I remove the prevois project, I am afraid of that the new project won't work since that file is missing.
Thanks!

I used to move project between machines without any problem.
Edit the vbp files to change the paths using notepad, make sure you also change any of the controls locations to the correct depth, i used to find occasionally had one too many ../../../ depending on which machine i was on.

Dave,
Thanks! Yes, I open the .vbp in notepad, the strange thing is that in .vbp file the path is in current project, but when I open the project from VB6, and click "Reference", that reference's path is pointing to previous project again. If I save the project, and open .vbp file, the refernece path is changed back to previous project.
There are more than 10 reference, all others are ok, only this one doesn't work.
Did you encounter this issue before?

To be honest its been that long since i went near vb6, i can't remember..........hopefully never need to go near it again.
|
|
|
|
|
I also wish this is the last project in VB6. Thanks!

Why don't you copy the code to new files in a new project? (Know it is a boring way. But might help you if you lack time)

Hi I'm currently developing graphics manipulation program with GDI+ under Visual Studio 2010 Ultimate RC - the language is Visual Basic. I'm writing the program on my laptop and I test it on my desktop PC, my desktop PC is:
OS: Windows Xp SP2
.NET Framework 3.5 SP1
CPU: 1.8GHz P4 Northwood
RAM 1GB
My Laptop is:
TravelMate 5720G
OS: Windows 7 Ultimate
.NET Framework 4
The application I'm developing uses GDI+ for all graphics manipulations. My project framework is .NET 3.5 SP1. The compiled executable used to work fine on my old desktop PC, but today I tried to start it and windows XP gave me the following error:
'(myprogram)has encountered a problem and needs to close. Send Error Report/Don't send'
The program I'm developing is for educational purposes in educational centre near my town and
there teachers have only two PC with windows vista and others run on XP, so its very important for me to get my app working on XP.
Thank you in advance.

that basically tells me you did not meticulously provide error handling in your app.
You need to add some try-catch constructs, where an exception when caught also gets displayed, say using MessageBox.Show(exception.ToString())
The first place to insert such try-catch construct is in your very first code (so it covers everything that gets executed on the main thread from there), so go search for file program.vb

Are you trying to run a 'release' compile?
If so, uninstall and install a 'debug' compile - you should get a more meaningful error message concerning an unhandled error.

is that Excel screenshot just an example of the kind of dialog, or is it actually Excel having a problem?
you do know Office automation is tricky, and particular to each and every version of Office? you cannot assume a solution that automates Office 2003 to also work on Office 2007 or 2010, they are not compatible.
please try and provide more detailed and more accurate information, so somebody can provide specific help.

In which case, I presume the application is crashing immediately on starting. Is this the case?

The screenshot I provided are just example of the kind of error dialog I get. And yes the application crashes right on the startup.

In that case, I suggest you follow Luc Pattyn's original suggestion of using a try/catch block, and provide the error message so people can have a look at it.

This is all code that resides inside Form_Load event:
imgMain.AllowDrop = True 'picture box control
strDefDir = My.Computer.FileSystem.CurrentDirectory
Me.SetStyle(ControlStyles.DoubleBuffer, True)
Me.SetStyle(ControlStyles.UserPaint, True)
Me.SetStyle(ControlStyles.AllPaintingInWmPaint, True)
Me.UpdateStyles()
penRegionPen = New Pen(Brushes.Black, intCropPenSize)
penMyPen = New Pen(Brushes.Lime, intCropPenSize)
penMyPen.DashStyle = DashStyle.Solid
penMyPen.Width = 1
I've put this iside 'Try.. End Try' statement but the problem still exist and it gives me this error window(this time i put the original error window, sorry for showing it so late, I didn't thought that the problem might be so serious):
http://www.mediafire.com/imageview.php?quickkey=jmddjtvzzjm[^]
And this error is occuring only on my Win XP machine, on my Win 7 laptop there is no problems at all.
This is all references that my project uses:
Microsoft.VisualBasic.PowerPacks.VS
System
System.Core
System.Data
System.Data.DataSetExtensions
System.Deployment
System.Drawing
System.Windows.Forms
System.Xml
System.Xml.Linq
Tommorow I'm going to test my applications on other XP machines, I hope that the problem is in my PC and not in the application...

Look for your program.vb file and give that one a try-catch, as I said earlier. It will catch many more potential problems as a safety net, not as a remedy, and probably tell you what your current problem is.

Oh gosh I finally solved the problem it is in this reference:
Microsoft.VisualBasic.PowerPacks.VS
I was using print to file option of the PrintForm dialog in Visual basic power packs
when I remove that reference everything start working fine again and now I'll made it before the deadline, thank you for all advices

Still, the issue is your program should have told you what was the problem, by testing return values on system calls that don't throw exceptions, and reporting exceptions when they occur, and not by dying silently.

Hi,
I have mdi [arent form. I want to fit it to any size of a window resolution and any child form automatically to fit inside the mdi parent form.
thanks
|
|
|
|

If you are asking how to make your MDI parent form fit the screen, you just need to set the WindowState property of the form to Maximise. Then if you set the child forms WindowState to Maximise as well then they will automatically fill their container. If you are asking about repositioning controls according to the screen resolution, you should use containers such as Panel, FlowLayOutPanel etc and set the controls Anchor and Dock properties accordingly.
Happy Coding

Have a look at this article:
Designing Resizable Windows Forms in Visual Studio .NET[^]
It demonstrates the "new" way of designing resizable forms using the anchor and dock properties provided by .NET.
In some cases you might want to resize the sizes of other types of controls on the form, eg. textboxes, comboboxes etc. That's the "old" way, and it's more complicated. If for instance you change the size of a textbox on the form, you might need to chenge the font size too or the box will become to small for the text, which will lead to nothing showing.
There are a lot of 3rd party libraries that can be used for this king of resizing, for instance this:

Hi,dear all,
I am using Window XP (SP3), I create a project using VB6.0.
When I run the program from VB, it works fine, but When I use InstallMaster to compile to generate setup file, I got the following error:
"To deploy MS Jet 4.0 SP5, you must install MDAC 2.6 to your development system".
How can I know if I already have MDAC installed in my computer? if yes, how to check its version?
If I didn't have it installed in my computer, should I install MDAC 2.6 SDK or MDAC 2.6 RTM?
Thanks!

XP SP3 has MDAC 2.8 already installed. You need AT LEAST 2.6 installed.

Easier asked than done. You need this[^] tool to determine that.

Dave,
If XP Sp3 already has MDAC2.8 installed, why was I asked to install MDAC2.6?
If I really need to install it, what type of MDAC2.6 should I install, SDK or RTM or someone else?
Thanks!
