Resize Form To Resolution

Top Score Score · September 18, 2003

Hi,

How can I make it so that no matter what screen resolution my application runs on, that it resizes the forms and all the controls to work with that resolution.

I am so close to getting it out onto the market but this one thing is holding me up.

The application was build on 1024 by 768 and needs to run on 800 by 600.

Can someone please give me a hand.

Thanks.....Dale

This might help.

I think with this you'll have some troubles... specially making the controls smaller...

The point is that certain controls are not user dimensionable (as long as I know), like the ComboBox for example! You'll allways have to play with the font size.

This method brings a new issue... the height of the combobox actualy really changes in integer gaps...

If the issue is to have a windows always maximized in diferent resolutions it's a easy task, but if you want to let the user resize the windows freelly you'll have trouble...

..might be of some use. I wish I knew if he'd continued work on it or not, as it's not quite complete.

I didn't read the complete article but what I undestood from it and from what Top Score asked it's not quite the same thing...

I think he wants to resize the complete layout, including the font size on the controls... like chaging the size but keeping the aspect ratio...

Am I wrong?

And that aspect ratio is the thing that brings more troubles... :)

If put to work wold be a very nice tool ...!

Hey,

I have seen that article a dozen times, I have read through it but it is not exactly what I need, you are right.

Yeah the fonts don't need resizing, they may I will just have to check. Although it might be best If I did??

But yeah the whole form including the controlls.

I have tried other methods like anhoring, when I put in on another computer the form I tested it on just goes blank and every loses its size back down to a small form. And this is a full screen form :confused:

And just to confirm it is when the window automatically adjusts to the size of the screen, not for user resizing.

I use VB.Net 2002

I aggree if this could work then it would fix alot of peoples problems, thats for sure.

I await the reply

I really don't know how you'll do this...

The only real problem is in the controls that are not sizable...

I told you... the textbox and the combobox are the two better examples! You can't change their height without changing their font size!

I think you can ajust the components on 800x600 and 1024x768 and make some kind of ratio to apply to the components sizes to make them grow or shrink with the form size beetwin theese too values... get it?

I think its the only way...

Yeah this is basicaly what i want to do. I am still learning .Net and I am only 16, are you able to give me the sort of code that I could use??

Resizing with a Ratio

I am working on a class that iterates through every control on a form, resizing and repositioning every control. I wouldn't mind a little help in the Font department though. I'm sooo close to finding an equation to universally resize the fonts by breaking the font into it's composite peices ..resizing then reassembling them.

Anyhow to get you pointed in the right direction say you designed the forms in 1024 X 768..and you are going to switch resolution to 800 X 600...1024/800 = 1.28 and 768/600 = 1.28 now you have your 2 ratios for both width and height. You can use these ratios to resize (current height = 100, so 100 / 1.28 = 78.125 <-- your new height) and (top = 548, so 548 / 1.28 = 428.125)...Now as you know sizes often are expressed in floats so you'll have to do quite a bit of casting and numerical conversions..as you'll see when I post my code later. And of course when I refine it I will post it on Winforms.com for your coding pleasure =D.

OK as promised here's my super sloppy Resizing Code...I've added a few lines that basically just resizes your text to fit in your controls. This would not be a good idea if your using word wrapping..Most likely you'll want to comment it out. Speaking of comments ..this is a work in progress and I'm not one for inserting comments in my test code. Hope you all can Disect reconnect and resurrect this snippet to serve your resizing needs.

P.S. I place this code in my constructor of my form..it should detect the current screen size excluding your Task bar and any other utility bars i.e. MSOffice bar etc..I don't suggest ever calling this code from a paint event as it will most likely cause an infinite loop or other unexpected results

Drutchlin · October 24, 2003

Also I think you can delete the second Argument in FinanceScal() and all references to it

Drutchlin · October 24, 2003

Any questions or comments ,other than why I have posted 4 times in a row when I could have obviously included everything in one post ;)~, are welcome. SIA If I don't always have time to reply to questions

Top Score Score · October 27, 2003

Ok, been away sorry.

This is in .net format isn't it??

So where exactly do I put it?? Is it in the windows design generator??

Dale

AlexCode · October 27, 2003

For your question about the Drutchlin code being .net or not I think you'll have some huge problems understanding it! :D

Anyways... It's C# code! And place it where you usually put your Subs and Functions... It isn't Design Generated code...

Drutchlin · October 28, 2003

That's right it is C#.. you should be able to use most of the functionality if you convert it into VB ...I have almost finished a class...all you'll have to do is reference it create an instance and call a method..I will try to have it up in a couple of days

Top Score Score · October 29, 2003

I haven't ever started learning C# yet, but I know there are aa few convertors around, anyone recomend one??

Thanks for all the help, it will help me and many others.

Dale

AlexCode · October 29, 2003

There's really some convertors but if you know vb you know C#...

It's just a matter of learning few declaration diferences... a good thing about learning that diferences is that you'll learn another language...

Second thing is that the convertors aren't fail prof...

HKP · December 30, 2003

Hey Drutchlin, Was just wondering if you had an opportunity to post the class for resizing a windows form based on screen resolution. In your earlier posts you had mentioned that you were working on a class and would post it in couple of days. Instead of reinventing the wheel if you have one already finished was thinking of using it. Thanks a lot!!

Drutchlin · December 30, 2003

Sorry all...I've been very busy at work trying to rush product to the market. As soon as things slow down I'll finish up the class. I have a VB app that also needs the activeX control..I've still yet to study up on interopt to create the activeX control...I do have a C# class already complete..if you would like I could post it ..let me know. the font resizing is still a little quirky..if anyone has any solid info on resizing fonts..I would be greatly in your debt. Fonts are tricky as they are made up of variuos elements..and also depend on dpi. http://www.hut.fi/u/hsivonen/units.html and

HKP · December 30, 2003

I would appreciate it if you can post the C# class. I am afraid I may not be of much help with the fonts but I will try to play with your class and search over the web also to find some pointers. Thanks a lot!!

Drutchlin · December 30, 2003

Copy this code out place in a new class name it Resize. See the comment below place the name space of your project name in place of the comment. Compile as a dll..reference your dll...create an instance of the class and simply call CallScale(this)..passing this, meaning your form, as the control...it will iterate through all controls on your form..including controls contained in other container controls. In the code resizing the fonts you'll notice a 5f..this float can be played with a bit to get different results..If you've any questions please reply!

Thanks Drutchlin!!

Drutchlin · December 30, 2003

One more thing...this class if you've noticed...was designed to resize FROM 1024 X 768...If you have designed your application in another resolution simply replace all occurances of 1024 and 768 with the correct resolution
