If you want to pre-fill InfoPath form before user gets his/her hands to it... you have two ways to do that: Call Web Services from InfoPath It normally takes quite long Dynamically create InfoPath form instance Fast and there isn't any limitations where...

Excel Services is pretty nice for displaying Excel files over the network. But if you're developing Excel Services solution for the first time you might first think of the limitations or something that forces you to build your overall solution in certain...

Disclaimer/Important notice: I sometimes go crazy with my favorite programming tools. I use my imagination to do things and try to forget all the rules that I normally would keep in mind when developing applications. This post is one of those moments...

I have been asked to build this kind of example sooooo many times that now I really need to write this down :-) This stuff isn't rocket science but I have got so many emails about this so I just want to answer all those questions at once. So I have previously...

I posted awhile back about InfoPath and Web Service data connection and I got question about using own web services in SharePoint (or at least I interpreted it that way :-). I tried to describe idea to have own custom "proxy" web service that would do...

I was asked to create simple demo that demonstrates MS CRM inside custom .NET application. So I created small win app with just couple of controls to make the demo pretty simple. If user presses Edit customer button then new form is opened and that will...

If you have your SharePoint application running on Server1 and you decide to move it to Server2 with backup and restore... you'll (may) end up having application at the Server2 that doesn't have all the necessary timer job definitions. There is however...

I was working on SharePoint case and found myself staring at the logs... again :-) I found 11 lines with " Failed to determine definition for Feature with ID ..." and it was repeating quite often. And that error is something new for me... And if you have...

I got email from Philip Edney with a hint that how you can install Windows SharePoint Services 3.0 Tools: Visual Studio 2005 Extensions (VSeWSS) for none-Windows 2003 server OS. Of course since that's not supported you'll have to do small registry hack...

Every SharePoint developer knows that you need to free resources that you have used... like SPWeb (and others too!). Most often freeing up the resources are easily managed with the nice using -statement like this: 1 2 3 4 5 6 7 using ( SPSite...

That title says it all! Well I was working on case where SharePoint was configured to use external authentication. This external authentication was hosted outside SharePoint and it could be used by many other services too. End users of SharePoint would...

I just wanted to make quick post about starting the workflow from code. You might want to use this stuff in your eventhandlers for starting workflows automatically in some weird scenarios. But no more explaining since this is pretty straightforward. Here...

A while back I got a question that how would I solve "feedback feature request" for my customers case (platform was MOSS 2007). Idea is that from every page of the portal you could go and give feedback. And if you do give feedback it would be important...

If you have worked a lot with MOSS you probably know how to make new page layouts. But if you create new page layouts you might sometimes wonder that how could I add some common functionalities to my page layout pages. One example could be localization...

I have used Windows Vista from last November and now I have noticed that I'm really heavy user of search. Before Vista I had a lot of problems finding my stuff because I just couldn't remember where I have saved my files. I used my own directory structures...

Have you done nice Feature (or set of Features) that you want to deploy using SharePoint Solution deployment? Great. Have you already deployed your newly created solution? Great. Are you missing files from your features folder: TEMPLATES\FEATURES\ YourCompany...
