c# - Resizable window w/ taskbar button but w/o the title bar -


Try to override CreateParams as suggested, however, the taskbar button is not visible on initial load. The user must activate another window, then the goal window must be reactivated before the taskbar button appears.

Why is this for some reason? How do you work it?

WS_EX_APPWINDOW Flag ExStyle Try adding property of CreateParams.

Windows is estimating whether there should be a taskbar button in your window by viewing captions and other styles. WS_EX_APPWINDOW lets explain it so that Windows does not require estimation.

WS_EX_TOOLWINDOW makes it clear that you should not have a taskbar button

edit: like this 

  create protected overrideParamelParamas {{CreateParams cp = Base.CreateParam; Cp.ExStyle | = 0x0040000; // Add WS_EX_APPWINDOW cp.Style & amp; = ~ 0x00C00000; // Remove WS_CAPTION cp; }}

This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
