asp.net - Remove Image in excel header after exporting the gidview -

-

Please help me on how to extract an image in my Excel header I use the Excel export command as the source data of gridview Using

My code is generating here 

  Response.AddHeader ("content-effect", "attachment; file name =" & strfilename & amp; ".xls") Response.Clear () Response.Charset = "" Response.ContentType = "application / vnd.xls" dim sw System.IO.StringWriter = New System.IO.StringWriter () Dim as HTW In System.Web.UI.HtmlTextWriter = New System.Web.UI.HtmlTextWriter (SW) grvData.AllowPaging = false grvDa Ta.AllowSorting = False PopulateGrid () grvData.RenderControl (HTW) Response.Write (sw.ToString) Response.End ()   
 Everything was set-except that my title There was a blank header name due to the image, which was now shown - the image came from the gridview (I am using the arrow for ARC and desc) - sorry, I can not post any image here now! /p>  
 
 
 Give it a shot to the ClearControls method It turns any control from the grid before exporting Should give:  
  protected void btnExport_Click (object sender, EventArgs e) {Response.Clear (); reaction. Buffer = true; Response.ContentType = "app / vnd.ms-excel"; Response. Charset = ""; System.IO.StringWriter oStringWriter = New System.IO.StringWriter (); System.Web.UI.HtmlTextWriter oHtmlTextWriter = New System. Web.UI.HtmlTextWriter (oStringWriter); This.ClearControls (DataGrid1); DataGrid1.RenderControl (oHtmlTextWriter); DataGrid1.GridLines = Gridlines Both; DataGrid1.Style.Clear (); Response.Write (oStringWriter.ToString ()); Response.End (); } Private Zero ClearControls {for (int i = control.Controls.Count - 1; i> = 0; i--) {ClearControls (control.Controls [i]); } If {if (control.GetType () getProperty ("SelectedItem") = Null.!) {LiteralControl is literally = New LiteralControl () ((Control TableCell)!); Control.Parent.Controls.Add (literal); Try {literal.Text = (string) control.GetType (). GetProperty ("SelectedItem"). GetValue (Control, Empty); } Hold {nothing} at the end {control.Parent.Controls.Remove (control); }} And {if (control.GetType (.) GetProperty ("Text")! = Null) {literalControl literal = New LiteralControl (); Control.Parent.Controls.Add (literal); Literal.Text = (string) control.GetType (). GetProperty ("Text"). GetValue (Control, Empty); Control.Parent.Controls.Remove (control); }}} Return; }

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
