I've decided to make an new archiver based on existing dlls. Im aiming at a simple 7zip style archiver thats quadcore optimized and 8 core compatible (the 8 core part can wait cause amd's bulldozer aint out yet). I'd like to include [code]Where do I start? And where can I get the dll's? (multiupload.com links are nice).

Yup,not PHP but it's the same for readability)As you may imagine I want to make a simple text based rpg game, but that's not an important fact.The buttons btn1 to btn3 are already created at the designer, and there are going to be other procedures which will assign values to their text property according to the game context (main menu, combat, shopping, training, etc.) you're at.Ok, so what I want to do with that procedure I pasted is to parse the text of ANY of those buttons when I click them, and according to its value select a case which will trigger another appropriate procedure (now there are only msgboxes as placeholders for testing only).My problem is that I dont know how to refer to the originating class of the handled event! I mean, let's say I click btn2. I'll want to immediately get the text property of that button only and use it as the value for the select case tree. I suppose I need to put something at that ?I wrote there, but I don't have any idea. The first time I was so naive to put me.text in there, and of course it returned the form name. Is there's something to do this thing...? I thought at first it would be a very simple task, but I'm going nuts searching for a solution so it's like if it was not possible, but I find hard to believe that, because this would be very useful, right? By the way, what I want to achieve is not needing to make a separate procedure for each button and to avoid as well the need to move any game option to another procedure if later on I want to rearrange the menus, because I expect the game to have more than three buttons actually.

View 3 RepliesI am trying to understand how to interact with external DLLs written in C++ for use in my VB.NET application. I have some DLLs that a client wrote that do some math functions. Everything was working on a 32-bit machine. Because we were taxing the 32-bit machine we moved to 64-bit. Now we can't get the same functions to work. The DLLs were re-compiled as 64-bit DLLs and they still don't work. So my client wrote some dummy DLLs to see if we could figure out the problem. Here are the "signatures" of the DLL calls that I am making:[code]....Ultimately I would like to get to calling initialize_quiet and I am guessing at the format of the marshalling, const size etc.
View 3 Replieshow to write the code for my project.I am to base my new project on an existing one(existing one has code that works 100%)and create an Array of a structure that bascially holds the information from a summary form AND the totals from an AddToOrder_Click event. If you are still with me)... I cant figure out what the code is for my structure and Array so that I STILL have a Summary Form but I have an array that shows when I click my PrintPreview. So an Array is basically a "space" that holds information, like my summary form except it doesnt show until I click PrintPreview right?
If I just wanted to show the table then my code belongs in the PrintDocument1_PrintPage to show the array but the actual structure code belongs in the Click_Event of my AddToOrder? Please Please understand I AM NOT asking for anyone to write my code, basically I am asking for some clarification on what exactly creating an array from a structure is and therefore determing where the structure is to be placed in my code..
I am trying to create an interface between a third party application which can make use of C/C++ DLLs, but no interface directly to .NET. What I was hoping to accomplish (not sure if possible though), is create a very basic C++ DLL (not .NET), which the third party application would call directly. This DLL would contain a basic method such as "DoSomething()". Somehow, from my .NET application, I want to "listen" to this DLL and "takeover" the DoSomething() method, and then returning the result back to the DLL, which will in turn return the result back to the calling third party application.
I don't even know if this is possible because I'm sure I would somehow have to get a hold of the memory space of the DLL as initiated by the third party application. Also, it seems that creating a managed DLL does not work, based on feedback from other individuals who have tried this.

View 3 RepliesI'm experimenting with a plugin architecture for my company's internal business system. I have managed to read all .DLLs in a Plugin folder which implement a specific interface. What I am trying to figure out is the best method of communication between the "host" MDI parent application and forms that will be in the .DLLs which I intend to make MDI children.
Currently, I am returning just ToolStripMenuItem objects from the .DLLs to add to the MDI Parent. I've also tested that events wired in the .DLLs to the ToolStripMenuItems do propagate to the code in the .DLLs. I've also managed to return a Form object via the interface and open that form, as the Plugin folder is being "scanned".
However, I am not clear how I would make these forms MDI children. Also, any other forms living in the .DLLs will also have to be MDI children. I created a VS 2008 Addin project just to see what's going on, and it seems that the Addin accepts an Application object on which it adds to the ToolStripMenuItems and does other operations. The code to build the menu inside the .DLL. This is opposite of what I have done so far, where the MDI requests a ToolStripMenuItem from each .DLL and adds the returned object to its own menu.
Would designing my plugin architecture to accept an application object in the same manner the only way I could get forms to open as an MDI child? Am I asking for other, currently unknown to me, headaches by NOT passing in the application object to the .DLL?

View 3 RepliesI have this vb program that uses 2 dlls i made in c++, the dlls are attached to the project and are set as "copy always" and in vs debug mode they work fine, however when i try to publish the program and run it it can no longer find the dlls even tho they are right there next to the program itself the dlls are declared as following: Private Declare Function Trace Lib "Lowstuff.dll" (ByVal targ as IntPtr) As UInteger.so what im thinking is that maybe theres like a switch in project settings i didnt flick or maybe i need to specify the dll with full path or wut?
As it turns out it had nothing to do with vb afterall, it was the c++ dlls that had to be made as static. However now i have a new problem: Im geting a bunch of overflow exceptions from my program but only on other computers, in the dev machine it reports no errors or warnings whatsoever, i also went over function where the error was generated and all the functions it used and detected no fault so how am i supposed to track these down?

I have a VB.NET/C# Visual Studio 2010 Solution with a bunch of projects that depend on about 30 third-party DLLs all from 1 vendor. This third-party vendor recently released a new version of their software so I would like to parallel test their new software and my enhancements until I am comfortable to switch over. What is the best way to setup a solution in Visual Studio 2010 so that I can use the code I have developed on top of these third-party DLLs and have the opportunity to easily switch between:
(1) the new version of the third-party DLLs [for my testing] and
(2) the old version of the third-party DLLs in case I need to debug some problem a user is having.Third party assemblies ARE NOT in GAC (they're currently in a folder on a network drive). They are NOT strongly signed (ran sn -vf ). They are changing from version 5.4.618.0 to 5.4.619.60.
How can I add a new form to my project that is based on an existing form in the same project?
I want to add a new form to my project with the same control layout as an existing form in my project, and then just change the label text and so on.
I tried to just copy and paste, then rename the pasted .vb file, but get an error when I try to open it for modification.
is this possible? can not find how to add a new project to the existing solution. or, this feature does not exist in vb express?

View 2 RepliesI'm creating a notepad application with richtextbox as the editor. I have pretty much all of the funtions I want for the application itself, but I want a code that will help me understand whether it has been saved to the computer already.For example, just like in notepad, where you can open a .txt file, and if you don't modify it, it won't prompt you to save on application.exit(), but if you do modify the file in any way, it will ask you if you want to save, and it will automatically save over the opened file without popping up a savefiledialog.
I want my application to do the same thing, and also with any files that I save. For example, when I save a new file, after it prompts me with the savefiledialog, and I save the file to a directory, on my next "save" not "save as" I want it to recognize where it previously saved the file to overwrite it without prompting me with a savefiledialog like "Save As" does.There must be a code to recognize where it was last saved, or opened, but right now my default directory ("Initial directory") for both the open and savefiledialogs are set to the C:/ direcotry.
Is there any way to add new properties to a control? For example, I'm using an "OvalShape" from Microsoft's Powerpacks, these are designated as "Cells". I would like to add properties to the class itself (if I had a physical class to edit) for different processes such as "energy level", "family number", "mutation", etc. General variables that are either Boolean, Integers, or etc. If there isn't a way to edit the powerpack class itself, is there a way I can use the ovalshape power pack in my own class and add extra properties to it myself?
View 3 Repliesi have a program called Vip Task Manager.This program lets me set up task which others have to complete.When they are done with a task they have to mark it "completed" and make a report on what they have done and used to perform this task.Vip Task Manager has a button which directs them to an upload form, now when they press the "open" button I would like this to happen: Open a certain report making program I made myself.When they finished writing their report and press save, the program saves this report on a dedicated network HDD (.txt file) and closes itself.Then add the file or link to the upload form in Vip Task Manager.What it all comes down to is that they dont have to minimize Vip task manager, open the report making software, save it, go to vip task manager, press upload, press open, look where this file is saved, select it, and upload it.now, typed in red is whats already been taken care of.The rest, I have no idea where to begin to be honest.First I want to find out how to retrieve that a button is pressed in a existing program.

I'm trying to add a folder and some files within it to a Visual Studio 2010 Express VB.NET project. I have read the answers to questions on this subject here and here.
