New Post: Upgrade web part

dangallo — Mon, 26 Jan 2009 17:03:22 GMT

I've used the Web Part Template project to create a new web part, and rolled this out to our development server using the generated ".wsp" and Setup file. This all works fine.

However if I then decide to make changes to the web part code, and upgrade it on the server, the ".webpart" file is not updated in web sites that use this web part.

If I manually update the ".webpart" file then existing web parts fall over with the following error: "Web Part Error: A Web Part or Web Form Control on this Page cannot be displayed or imported. The type could not be found or it is not registered as safe."

This error presumably comes up because the ".webpart" file version doesn't match the version of the web part that was added to the page.

What am I doing wrong - what's the correct way of upgrading a web part in SharePoint using the SharePointInstaller?

New Post: issue with CreateCabDDF.vbs

Hi,

just wanted to let you know that the following bit of script in CreateCabDDF.vbs is causing problems when you have sub folders inside a feature folder, as the condition will unwantedly evaluate to true for each level below a feature folder.

if (sRelativePath <> "" and InStr(1, sFolder, "FEATURES") > 0) then
sRelativePath = "FEATURES\" + sRelativePath
end if

I have modified my version to fix this problem:

if (sRelativePath <> "" and InStr(1, sFolder, "FEATURES") > 0 and InStr(1, sRelativePath, "FEATURES\") < 1) then
sRelativePath = "FEATURES\" + sRelativePath
end if

Regards,

NEW POST: wspbuilder or this template

This is regarding this template.
I have found one more tool on codeplex called wspbuilder(http://www.codeplex.com/wspbuilder#CommentsAnchor)
which do similiar things as visual studio project template. Although vs project
template is a template ,but the end result of both tools seems to be the same.
What is your recommmendation about which one to use.

NEW POST: Nice work...

Copying DLLs during post-build:

TheKid — Thu, 22 Feb 2007 16:39:10 GMT

Thomas,

It sounds possibly like a timing problem. In the post-build it copies the DLL, but it has finished copying by the time the script is looking for the DLL and so does not get included.

You might try this at the begining of the ddf script...

Dim starttime, exittime, x
x = 0
starttime = timer
exittime = starttime + 5
do while timer < exittime
x= x + 1
loop

this should give it 5 seconds bore it starts...I haven't tested it, but you get the idea

Copying DLLs during post-build:

Copied message from my blog...

Hi there, I am trying to use your nice and handy template, but I can’t get it working so that it updates the .dll files in the GAC folder inside the .wsp file.

I have a number of .cs files added under Controls, and when I build the project the result(a .dll file) is placed in the bin\debug folder. Then in post-build i copy the .dll file to the GAC, but it is newer updated in the .wsp file. If I remove the file and build a new .wsp file, witch does not contain my .dll file, and i afterwards add the .dll again, an the builds the .wsp file again, it is updated inside the .wsp file. Because of that I think it is somthing about overwriting the existing .dll file in the .wsp that fails, but i can’t find out fixing it!

Please help
