View 1 RepliesI have a webapp where a datagridview is populated with records from a database and one of the columns is a download link to download the zip or exe file. We have the zip files on our server, but not the exe files as those are on another department's server. We have all of the file available for download, but if the user as an option selected in a dropdown, those url's in the gridview are re-formatted to be the exe file's on the other dept's server, however they don't have all of them (some 20% are missing) which means if the user click's the link they get their server's 404 not found page and can't download the file.
My PM (Project Manager) is asking me if I can have our webapp detect that the file doesn't exist on their server and instead of them getting the 404 page, they don't leave our app at all and get a javascript popup window or the page is refreshed with a red mark (and a message) next to the link they clicked on, is something like that possible? I have 2 restrictions with this, I can't modify the database because it doesn't contain file paths, it only contains a small portion like (Clinton County, Eaton County, Traverse County, etc..) and the rest of the url is formatted on the fly when the page is rendered, so there's no way to mark the missing files and there's no way we can host the files.

I got two issues getting my application to download a file. One small and one rather big.The downloader seems to have an issue using the users full download capability while the downloaded size is under 1 MB. As soon as it hits that, it seems to speed up with 10-100 times the previous speed.(Snippet at the end of the post)It seems to have to do with the filesize, which is about 5GB. As soon as my application hits about 1GB it completely locks up. (Without an error message, which I do have built in with a try...catch statement)I actually have to force quit the app to make it stop.It works perfectly fine with a 20MB file.I have the idea it's because of the int64's I use. But I need to use those (afaik) due to the big file size.[code]

View 3 RepliesI support applications in VB6 and VB2003, and I'm trying to upgrade the VB6 app to VB2005, so I have three versions of Visual Studio on my pc. I ran VS2005 and opened the VB6 app to launch the upgrade wizard. It seemed to run fine until it threw an error saying it could not find the project it just created. The project I'm trying to upgrade is called MGxFromSAP.vbp. The error said it could not find MGxFromSAP.vbproj. The project file it actually created is called MGxFromSAP.vbproj.vs7.vbproj. When I try to open this project in VS2005 it says it was created in an earlier version of Visual Studio and needs to be upgraded.Did it perhaps invoke the VB2003 upgrade wizard instead of the new one? How would I be able to tell?
Should I just let VS2005 upgrade the vs7 project or should I try to deinstall the old VS2003 upgrade wizard and rerun the upgrade from scratch?
