c++ - invalid memory when using classes from a dll -

-

This is the first time that I have tried to export a class from Dell. What I have done: - Creating an interface (pure virtual methods only) - This interface has been implemented in DLL with a class which is being exported - the class is the method released which is deleted on this pointer - Factory class is created with a static method which gives an indicator in the solid square but as the interface. This class is exported -

The problem is that when I use this DLL in any other project, everything is destroyed. Okay as long as I call the release function on the object. Then it shows a failure window with an "error message" _ASSERTE (_BLOCK_TYPE_IS_VALID (pHead- & gt; nBlockUse); "

Has this happened to someone else? I know that this CD It is as simple to forget to use when you start C ++, but as I said I started it.

Thanks

Is your factory function defined in the header? If it is, and the object is hidden For example, in the new header, and by calling delete from within the DLL, this error may occur

For example, Should appear: MyInterface {Public: Virtual Zero DoSomething () = 0; Virtual ~ MyInterface () {}}; __DesclassPC (Dilexport) MyInterface * __stdcall MyInterfaceFactory ();

MyInterfaceFactory () should be contained within the DLL in the implementation.

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.

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...
