delphi - WMDropFiles problem on win7 -

-

I have implemented the following procedure and it works properly when I run Vista Vista, Computer # Compiling on 1. If I share the .exe file I created on win7, computer # 2, then it runs just like that. The problem is that when I compile the computer # 2 it just does not accept it That has dropped anything on the application. There is absolutely no answer in this code. It has been created and compiled without errors or warnings. I have been searching for a while for some time, which explains why this happens or someone else with this problem.

The use of both the computers Delphi 2010 is installed with the same component.

  1. Is this the way that users allow files to be left on the file? If not, how should it be done nowadays?
  2. Why does any idea work on computer compiled on computer, but computer not # 2? (The program works properly on both computers when compiled on the computer) #

    Any help or comment is highly appreciated. 

      Process TfMainForm.WMDROPFILES (var Msg: TWMDropFiles); Const Maxlegram = 255; Var nFiles: integer; I: integer; FileName: Sir's [0..max lamp] sir; Filename: TStringArray; Get started / Get the number of files nFiles: DragQueryFile (msg.Drop, $ FFFFFFFF, Filename, MaxLenth); // file name setlist (filename, nffile); I: = 0 to nFiles - 1 start DragQueryFile (msg.Drop, i, FileName, MaxLength); Filename [i]: = fileName; End; // Add File ProjectHandler.addFiles (fileNames); // Release Memory Dragfish (msg.Drop); End;  
     
     I'm going to make a wild guess that if you have IDE # 2 on the computer It is sure that if you compile on computer # 2 but begin executable from IDE with Explorer, then it works. The last piece of the puzzle is that I bet you as an administrator on your IDE Are running  
     On Vista and Windows 7, you can not send messages in a process with a high integrity level. If your process is being run as an administrator, then it will have a higher level of integrity than Explorer and therefore the discarded files will not be accepted.  
     If my guess is correct then I would recommend that you stop running Delphi as an administrator, this is not needed for it. For  
     or not  WM_DROPFILES  is a reasonable perspective, I do not see any problem in using it.

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...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

c# - Client template not working with custom helper action methods -

I am using RVC view engine with MVC teleicent control and ASP.NET MVC3. For example, I have my helpful supporting methods, for example: public static object category editing (this is UrlHelper urlHelper, int classId) {new {controller = "category", action = " Edit "id = categoryId}" } I have an AJAX grid and I have my own column template, there is a link by going to Action Action Method in the Country Controller, but I do not know how to display it Be done correctly I currently have this but it is not working: column.Bound (x = & gt; x.Id) .client template ("& lt; a href = \" " + Url.RouteUrl (URLCategoryEdit (Int32.Parse ("& lt; # = Id # & gt;")))) "Edit"> When the grid loads, it gives the following exception: The input string was not in the correct format. So I'm assuming that is int32.Parse ("& lt; # = Id #>") is incorrect. try this: public static object...
