My wizard solution is something used by the clients developers, so it is more of a component than an application builder.

Just out of curiosity, and I am definitely not the one that would try to stifle your ambition, but why are you trying to reinvent the wheel that was just built?

It would seem to me that if you expose a good object model, extending an application built with .NET would be trivial without all of this, just having the clients developers use .NET to build extensions. Or are you looking for a mini environment like VBA in outlook?

I'm creating a Trainer Maker and I need to use a Form designer and I need to compile the form the user will create and I need to include some action like retreive the Textbox text to use it for a value and add Buttons action like to poke and freeze that's it.

I want to make something similar to Trainer Maker Kit (try to look at this application,check for screenshot, if you want of course), it's in VC++ i think and I want to make something that can equal the perfection of this program. Of course with the .NET Technology.

at this moment the form Designer works fine the only "hic" it's for that .CS file creating dynamicly. I'm suppose that is almost the same way as the C# IDE does, but i don't know very well how can I remake this. I don't want to make something big just a little file with the Window Form Designer code for all the controls and the action I will put on the controls.

I will check how can I figure it out, but I think I will post a lot of question on this board Smile | :)

I hope I don't bugging you with all my questions, if it's the case just tell me please

Thanks

I think there is a sample in the C# section called LiveCode.NET that does something similar. I havent checked it out yet, but I am sure you have seen it in any event...

Oops, I don't think I ever posted that message explaining Application.AddMessageFilter Blush | :O

AddMessageFilter takes an instance of the IMessageFilter interface, it has one method, PreFilterMessage which works like the WndProc except it returns true if the message has been filtered and doesn't need to be processed anymore.

So to use it:

public class MyClass : ......, IMessageFilter
{
  bool IMessageFilter.PreFilterMessage(ref Message m)
  {
    // do something with m
  
    return bShouldContinueProcessing;
  }
}

Then when you want to add it to the Message filter, Application.AddMessageFilter(myClass as IMessageFilter);

Nope, not with strongly-named assemblies they cannot be modified since a checksum is used to ensure they haven't changed.

There is a utility out there somewhere for combining multiple assemblies into one, but it can't be used on strong named assemblies because of the previously mentioned reasons.

I forget the name of the utility; maybe Rama Krishna remembers it (it was mentioned on the dotnet list not too long ago; if i remembered the context I could look it up).

TreeView node destruction % memory consummation

elnino8-May-02 16:11

TreeView intensively use an Hashtable of node where only insertion and none removal ops are perform.
Could you explains how cleaning is handle?

1) Does this involves that despite of manually removing, Treenode always remains in memory during execution?
2) or is it due to (TreeNode)collection processing whom release dead node.

How does this works anyway? how null value are detected?
waiting for your help, thanxs cause a lot Confused | :confused:

It’s due to Elnino! Poke tongue | ;-P

... No Seriously,

What you are probably seeing is the .NET garbage collector at work (or sleep, as it where), plus possibly the node (bucket?) caching mechanism in the internals of the TreeView itself. I haven’t bothered to drill down in enough detail to see if they are reusing their internal data structures of the later, but it’s a pretty fair assumption.

BTW, if you are holding on to a reference to a removed tree node to see if it goes away, it won’t happen... Wink | ;)

Re: i means Treenode never destructed

just use ildasm: the (assembly) hastable is nodeTable. grep it in TreeNode* + TreeView, you'll found two Op is performed:
create (powerful),
adding in TreeNode.Realize: treeView.nodeTable[htreeitem] = this;

several reasons:
* The paradigm it's to inherits from TreeNode but pb is that data aren't released Cry | :((

.
* Notice that original removal is slowest enough without inheritance
if time must increase sic.
* What i mean it 's not caching but smth like MapHandle % MapPermanentHandle in MFC. Imagine if nodeTable grow without freeing anytime you use it.

HTTP Error 407

I am trying to test some web services that are freely available on the internet (translators, weather, etc) using my Windows Forms client application. Problem is that I can't access any remote wsdl service description, I always get a message 'HTTP Status 407 - Proxy access denied'. Description for that message is that I don't have right authentication. I am supposedly cleared of any proxy interference on my side, is this a client side or a server side (proxy) message? At the same time all those services work fine when I access them using IE. I am probably missing something in the whole picture.
Any suggestions?

well, your customers need to to install the .net runtime which is about 20M. Without it your app will not work. Hopefully, within the next couple of months, years, the .net runtime will be installed by default. (I hope)

Not the whole framework. But they'll need the .NET redistributable installed. Just like you need the JRE to run that OMG | :OMG:

try here

http://www.msdn.microsoft.com/downloads/default.asp

then go to sw development kits/ms .net framework redistributable. you can get it from there. Also, I have heard that the .net redistibutable is available from Windows Update. I haven't seen this myself, maybe because I already have it on my machine but it's supposed to be there.

Exception.. what?

Rickard Andersson²⁰7-May-02 22:53

7-May-02 22:53

This code gives me the exception (don't remember exactly): "The instance object cannot be null"

Do you know whats wrong?? I don't think you'll need more code than this, because this is my exception!!

FileInfo fileInfo = new FileInfo(files[i]);
StreamReader streamReader = fileInfo.OpenText();

// Hela raden
string line;
do
{
line = streamReader.ReadLine();
// Does line contain "searchText"??
if(line.IndexOf(searchText) != -1)
{
listBox1.Items.Add(line);
}
}
while(line != null);

You need to check for line = null; before you look for the word. You put the check in at the bottom of the loop, but not before you use it Smile | :)

[Edit] If the idea of checking your break condition twice makes you uneasy you can do this

while(true)
{
  line = streamReader.ReadLine();
  
  if(line == null)  // break condition
    break;
 
  ....  // rest of the loop
}
