c# - WinForm: Inherited Panel wont Autosize -


first of all: english pretty bad. i'm sorry if there grammar , writing errors.

my question:

our company using same dll lot of programs. in on of multiused dlls, created basic ui object, used often. found bug, when dll used in specific programm:

my team created panel via winform. normaly works great: whenever start panel, form autosized according current free space got. realize this, used following code: 

this.tablelayoutpanelmain.autosize = true;             this.tablelayoutpanelmain.autosizemode = system.windows.forms.autosizemode.growandshrink;

no problems far. but, after specific panel used again in same program - think created panel inherited somehow - wont autosize anymore. instead got pre-defined size: 

this.tablelayoutpanelmain.size = new system.drawing.size(341, 69);

i dont have idea, why panel isnt reloading again , autosizing again. biggest issue here is, dont have access specific program, bug occurs , our dll used. know error somehow occours there.

i not pro-programmer. think has how implemented panel. think, created once, never again. there 1 panel, used pretty often. while doing this, wont refresh, nor using autosize function aymore.

to prevent bug, believe somehow have implement like: refresh, whenever used, please autosize.

but have absolutley no idea. i've never worked winforms, xaml. if me this, appreciate it.

the code:

    this.tablelayoutpanelmain.autosize = true;     this.tablelayoutpanelmain.autosizemode = system.windows.forms.autosizemode.growandshrink;     this.tablelayoutpanelmain.columncount = 3;     this.tablelayoutpanelmain.columnstyles.add(new system.windows.forms.columnstyle(system.windows.forms.sizetype.percent, 100f));     this.tablelayoutpanelmain.columnstyles.add(new system.windows.forms.columnstyle(system.windows.forms.sizetype.absolute, 16f));     this.tablelayoutpanelmain.columnstyles.add(new system.windows.forms.columnstyle(system.windows.forms.sizetype.absolute, 218f));     this.tablelayoutpanelmain.controls.add(this.panelpasswordrepetitionerror, 1, 2);     this.tablelayoutpanelmain.controls.add(this.txtrepetition, 2, 2);     this.tablelayoutpanelmain.controls.add(this.lblpasswordrepetition, 0, 2);     this.tablelayoutpanelmain.controls.add(this.panelpassworderror, 1, 0);     this.tablelayoutpanelmain.controls.add(this.txtpassword, 2, 0);     this.tablelayoutpanelmain.controls.add(this.paneldummy, 0, 1);     this.tablelayoutpanelmain.controls.add(this.passwordqualitybox1, 2, 1);     this.tablelayoutpanelmain.dock = system.windows.forms.dockstyle.fill;     this.tablelayoutpanelmain.location = new system.drawing.point(0, 0);     this.tablelayoutpanelmain.margin = new system.windows.forms.padding(0);     this.tablelayoutpanelmain.name = "tablelayoutpanelmain";     this.tablelayoutpanelmain.rowcount = 3;     this.tablelayoutpanelmain.rowstyles.add(new system.windows.forms.rowstyle());     this.tablelayoutpanelmain.rowstyles.add(new system.windows.forms.rowstyle(system.windows.forms.sizetype.absolute, 20f));     this.tablelayoutpanelmain.rowstyles.add(new system.windows.forms.rowstyle());     this.tablelayoutpanelmain.size = new system.drawing.size(341, 69);     this.tablelayoutpanelmain.tabindex = 0;

forgot this:

// pdfpasswordview //  this.autoscaledimensions = new system.drawing.sizef(6f, 13f); this.autoscalemode = system.windows.forms.autoscalemode.font; this.autosize = true; this.autosizemode = system.windows.forms.autosizemode.growandshrink; this.autovalidate = system.windows.forms.autovalidate.enableallowfocuschange; this.controls.add(this.tablelayoutpanelmain); this.doublebuffered = true; this.margin = new system.windows.forms.padding(0); this.name = "pdfpasswordview"; this.size = new system.drawing.size(341, 69); this.validated += new system.eventhandler(this.onpdfpasswordviewvalidated); this.tablelayoutpanelmain.resumelayout(false); this.tablelayoutpanelmain.performlayout(); ((system.componentmodel.isupportinitialize)(this.errorprovider)).endinit(); ((system.componentmodel.isupportinitialize)(this.markerprovider)).endinit(); this.resumelayout(false); this.performlayout();

so found out problem was:

it working if started via debug mode (attach process), not when started release. seems weird. seems release jumping on code.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
