I'm having trouble trying to access the different colour depths and sizes in an icon. Does anybody know how to load an icon into memory and pull the correct image depending on the system colour depth and users size selection?

I'm trying to provide different icons for disabled users but the imagelist will only hold one size and depth and the class is the same!

Datagrid IN a Datalist

So I have this datagrid in a web user control. The grid has some basic link buttons for functionality like Edit, Add, Update and Cancel. They all work fine when the user control is put on a web page.

I came across a need to have this datagrid repeat with some other information so I put the user control in a datalist. Now only the Edit and Add buttons work. I set some breakpoints, and it looks like any of the buttons located in the grid's EditItemTemplate will not fire their grid events. I set up some events and breakpoints in the datalist as well to see if the events were bubbling up somehow, but they weren't.
When I click on the Update or Cancel link buttons the grid reverts back to EditItemIndex equal to -1 or at least the edit line is going back to the regular ItemTemplate. I set breakpoints everyplace I was setting the grid's EditItemIndex, and again no dice.

Has anybody run into this problem? Anybody figure out a solution?

Protect the MSIL code?

How can I protect the MSIL code?
I've seen that Anakrino can convert MSIL code to C# code very easy.

Actually, if you're willing to do it, then what you could do is go into ILDASM, export the IL, and then move some of the class members so they're global level members, then rewrite the parts that call them to call them as global.

It makes Anakrino GPF becaue C# doesn't have any concept of global members. Cool | :cool:

Can you show me something, how to make a varible global? A tutorial?
Something?

recursively search the registry and delete text

I need some help. I need source code that will recursively search the registry and delete text found. It would need to work on 95/98/NT/XP/2000. I'm looking to return a list (perhaps in a list box) of all keys (ALL TEXT) that were found. If that Text appears anywhere in registry I want it added to my list. Then I can select/deselect what I wish and then delete the selected items. Allow someone to highlight and delete specific ones.
Any ideas?
Any help is appreciated.

Cheers,
Derek

I have been writing registry editors, searchers, and replacers for some time, so perhaps I could help. However, the core guts of almost all my code is in C or C++. I have tinkered with other languages, but none I have tried have efficient enough string handling to prevent the user from falling asleep.

One catch is the Win95 requirement, which eliminates the .Net languages. Thus, your options are to use strictly C/C++ to target Win95, or exclude Win95 and use .Net (and optionally a managed wrapper around some C++ to get decent performance).

If you can tell me how you wish to proceed, I can explain further.

Cheers

Yes, I would like some help. I emailed you earlier. Any help you could provide would be great. My primary language is C++. I'd like to have it list the locations and values of where it found the text that I am searching for, and allow me to choose to delete or not delete a certain entry.

Sorry for the late reply; I've been rather busy (as if I have lots of spare time Smile | :)

I've looked through my search functions, and can only find the more recent ones, which is fine, but they are very complicated (custom dynamic buffers and arrays, handle a zillion options, search binaries in various formats, some assembler, stored info to avoid recursion overhead, etc.). I am in the process of distilling one down to something digestable and more useful for your purposes. Will post (or email if too large) later today. Just wish I could find some of my regular stuff...

Cheers

Hello Derek,

I email you the rough code via CP's email system, which complained about the long text, so I hope it made it to you. If not, or it gets mangled, you can email me with an address I can send it to you as an attachment.

I reduced it all down to just a few hundred lines, so it should be pretty manageable. It's strictly search and callback with keypath, entry name, data, data length, data type, and where the string was found. That should be enough to load up a listbox or listview with. RegDeleteValue is easy to call after that.

Let me know if you have any questions.

Cheers

I think to make it com under the .net tab, the assembly has to be signed with a strong key and also there is a registry entry where you need to specify the location of the assembly. Anyway, I do not know the particulars.

Yeah it will appear under the com tab if you select the register for com interop configuration property but I can't find out how to do the same for .net interoperability. It can be done though since third party libraries appear under the .net tab.

Persisting Property of userdefined Collection type.

Hi,

I have exposed a property in a UserControl.
The Property is of Collection type. ( Collection of my Userdefined type).
When I use this Control in a Form, the Forms Designer allows me to Edit the
property (MyValues) using the Default Collection Editor UI.
But the Changes made to the Collection are not persisted in the Form code
by the Forms Designer.

//------------------------------------
class MyControl : UserControl
{

MyTypeCollection m_values = new MyTypeCollection(); 

public MyTypeCollection MyValues
{
   get
   {
      return m_values ;
   }
   set
   {
      m_values  = value;
   }
}

}

//------------------------------------

class MyTypeCollection : CollectionBase
{
Add(){...}
Remove(){...}
}

//------------------------------------

class MyType
{
int i;
bool b;

public int XXX
{
   get
   {
      return i;
   }
   set
   {
      i= value;
   }
}

public bool YYY
{
   get
   {
      return b;
   }
   set
   {
      b= value;
   }
}

}

How can I make the Forms Designer generate code for the Collection Modified at Design time.
Please someone Help me...

Zor,

Try to add the following attribute to your property:

[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
