The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

vb.net 2005, A form which is inside a panel of another form, the width/height seems to be locked, why can't I change them?

Asked by JeffreyDurham in .NET, Microsoft Visual Basic.Net

Dear Experts:

I love this service, as it is especially ideal for asking rather strange and specific questions. This is one that's kinda important to me, but I don't understand why it's happening.

I've got this form, which I have opened inside of another form, I have a main form, which holds my other forms, and it's got a menu (of buttons) on the left. anyways, it's nice, but one thing I want to be able to do is when I resize the main form I want to be able to resize my inner form. For some reason, whenever I do this, even though the events are triggered to resize it, the properties do /not/ change. I set them, and then read them and they are the same as before.

Here is my code for how I setup the form and how I call the resize on the other form.
The part you should especially note is formDataGrid.form2_resize() which is in the second class. There you can see where I set the width and height and then where I debug.print it is where I would expect those values to change.

Does anyone know what might be going on?
Thanks Experts! ~Michael
