c# - add behavior to group of windows form controls -

January 15, 2014

I am trying to copy the web functionality of a label on the text box which will be included in the text box Shows the type of I can add events individually but I am thinking that there is a way to add 'behavior' to the set of controls.

Please see example code:

  Private Zero label first name (link), object sender, EventErgus e) {HideLabelFocusTextBox (labelFirst name, textbox first name); } Private Zero HideLabelFocusTextBox (label labelTohehide, text box textboxes) {LabelToHide.Visible = false; TextBoxToShow.Focus (); } Private Zero TextBoxFirstName _Love (Object Sender, EventArgse E) {if (string.isnororappletyte (Text TextFastName Text)) LabelFirstName Visual = true; } Private Zero TextBoxFirstNameInter (Object Sender, EventAgds E) {labelFirstName.Visible = false; }  "post-text" itemprop = "text">  You can sub-class to control the text box (type your own text box)  < P> BTW, I have thought about it and I will take another approach:  
 I will override the paint handler of the text box and when there is no information in the text box, drag an information string in it .  
 Something like this:  
 using the  system; Using System.Windows.Forms; Using System.Drawing; Class MyTextBox: Textbox {Public MyTextBox () {SetStyle (ControlStyles.UserPaint, true); } Secure Override Zero OnPaint (PaintEventArgs E) {If (string.IsNullOrEmpty (this.Text)) {e.Graphics.DrawString ("My Information String ...", this.Font, System.Downings.brush.gray, New System.Drawing.PointF (0, 0)); } Other {E. Graphics.Drustring (text, this.font, new solidbrush (this for the collar), new system, drawing.POFF (0, 0)); }} Safe Override Zero On-Test Extended (EventArgs e) {Invalid (); Base.OnTextChanged (E); }}

Unable to get a fresh ASP.NET MVC project running with Visual Studio
2008 -



    This is a very basic question. I'm asking this silly about this, but I'm stuck something else and hopefully That something here can save me some time. So I open VS2008, to download the new ASP.NET MVC web application and click OK I want to prepare a test project. I debug my new MVC project to hit F5 then I enable the debugging to the web. I choose to modify the config file. It goes where I get a page load error.   Firefox can not establish a connection to the server on the local host: 57323.   Do I have to do something special for Vista? Or I should do something with IIS   Thanks for helping a noob   6/30/2009 update   OK, I think that I VS2008 may need to be reinstalled with the ASP.NET Development Server port. I have tried to do everything that I have suggested. I've marked Default.aspx as the start page. I tried to open it in Firefox / IE 8 / and Chrome. I tried to uninstall / reinstall ASP.NET MVC, which was not working. I tried telnetting with Putin with a local ho...






delphi - Mouseover hint for TChart series value -



    I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query:    chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End;    Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar.   Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...?      This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you:    Process TForm...






sql - Incorrect syntax near the keyword 'table' -



    I'm getting this error what I'm doing is trying to get data from a table and a db and Keep it in another DB and table. The tables are not exactly the same, I am using a FETCH cursor, so I get the first line from the DB1 table and then keep each column value in the declared variable. Then I run an assembly statement in db2 table and get the next value. All of these are working properly because it runs properly, but in the end I get this error,   Wrong syntax near the keyword 'table'.   In the entire transaction details, an attempt / catch with the error of expression in the Cat block, apart from this, I do not know what is the reason for it.   Here is the code    added to prevent additional result set at SET NOCOUNT - Interfering with the SELECT statement. Set nosenate on; TRY begin transaction sets ITENDITY column off --TURN identity_insert [dB] start [dbo] [TEST] all CONSTRAINTS table --TURN [dB] change [dbo] [TEST] NOCHECK barrier All -....
