Hi,
I have a project developed in VB.NET 1.1 (using VS 2003). The project has forms developed using the DataForm wizard (Connecting to Access Database, having a dataset and couple of adapter as automatically generated through the wizard - See attached screenprint "Original Form In VS 2003.PNG").

I converted the project to VB.NET 2.0 using VS2005 Express Edition.

Now when I tried to open the form from the converted project in Designer mode in VS2005 Express Edition, the form is not displayed, instead a text line similar to below (also see the screenprint "Converted Form To VS2005 Express Edition.png" attached below) is shown

<html><head><META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=UTF-8"><title></title><style>.ErrorStyle { font-family: tahoma; font-size: 11 pt; text-align: left}.DetailsStyle { font-family: tahoma; font-size: 10pt; text-align: left;text-indent: 0; word-spacing: 0; line-height: 100%; float: left; margin-top: 0; margin-bottom: 0}.StackStyleVisible { font-family: tahoma; font-size: 10pt; text-align: left; margin-left: 20; text-indent: 0}.StackStyleHidden { display:none; font-family: tahoma; font-size: 10pt; text-align: left; margin-left: 20; text-indent: 0}</style></head><body><DIV class="DetailsStyle" width="100%"><table border="0" width="100%" id="table1" height="100%" cellspacing="0" cellpadding="0"><tr><td height="40" bgcolor="#FF9999" width="8%" style="letter-spacing: 0" align="center"><img border="0" src="C:\Documents and Settings\Umesh\Local Settings\Temp\13622E.tmp" width="35" height="35" alt="ErrorImage" ></td><td height="40" bgcolor="#FF9999" width="91%" style="vertical-align: top; letter-spacing: 0" align="left"><b><font size="2" face="Arial" fontsize="70%">One or more errors encountered while loading the designer.

When I execute the converted project (Application), it executes perfectly and the form is also shown correctly.

How can I open the form in the designer so that I can modify the same?

Thanks in advance!!

Unfortunately, you can't do anything.

Re: VB.NET 1.1 To VB.NET 2.0 Conversion issue 80 80

So does that mean I cannot upgrade my application from .Net1.1 to .Net 2.0 anyway?? That's not good. I was planning to move my applications to .Net 2.0 so as to have more functionality included in the Project.

Re: VB.NET 1.1 To VB.NET 2.0 Conversion issue 80 80

Please check the code of frmdetailsdesign.vb of application written in 1.1 (old one).

You need to check or verify the code of existing project project before migrating.

Re: VB.NET 1.1 To VB.NET 2.0 Conversion issue 80 80

Now there is some interesting thing regarding VB.NET 1.1 to VB.NET2.0 conversion I came across today. When I converted the same project from 1.1 to 2.0 on a machine where I have only VS2005(prof) installed the newly converted project is working fine. i.e. I can open the form in the designer and make changes. I dont know how it worked .... I am trying to figure it out and trying to understand what worked in the converted project and what not worked in previos conversion
