ListView Items Add And General Coding
Mar 7, 2009url...I'm working on a simple MP3 player and are stucked on some Treview.Click and Listview.Items.Add problems which I cant seem to get past.What I'm trying to do is first with a button launch a FolderDialog to get folder path, when this is done I add the directories and subdirectories to tvFolders1 (Treview)For the whole procedure for this see classes LoadFolderTree(), LoadDir() and tvFolders1_AfterExpand.This seems to work just fine and no problems as far as I can see The we add a feature where user click on the Treeview (tvFolders1) and we are supposed to do the following: On tvFolders1_AfterSelect (when the user actually select something)I am the trying to add Items and subitems to the lvFiles control (Listview)[code]Now adding items and subbitems goes just fine if I:
1. Do not clear the ListView lvFiles in the Class tvFolders1_AfterSelect But I need that, I want the listview to be cleared before adding new items/subitems or we end up with an enormous list
2. Only add more items to the ListView without doing anything more
If I clear the ListView lvFiles in the class tvFolders1_AfterSelect the application will simply freeze and crash after clicking on any item in TreeView tvFolders1So basically somewhere in my code there is something causing this and that's were I need help, I where hoping someone could figure out what I need to do..I have pasted the whole code for that form because I suspect the problems are not in the adding/clicking on items but somewhere else, I do not know though.There is also a "bug/another big problem" in the adding of items/subitems to the lvFiles ListView and that is that the first mp3 file only gets added with file/path and not ID3.
ListView Rowheight Varies - Using ListView Control, With SmallIcons Style ?
Mar 15, 2012I'm using ListView control, with SmallIcons style in VB.NET. Icons are loaded fine, but when I start to scroll ListView down or up from scrollbar (clicking from arrows), rowheight drops to about half from normal in next 20-30 rows below/above upper/bottom row (depends from the scrolling position). After 1-2 seconds, ListView is "refreshed" and scrolling continues normally. When focus in on the ListView and I'm moving up/down with arrow keys or PageUp/PageDown, everything is normal. Any suggestions, what is happening? SmallIcons size is 16 * 16. Is it compulsory to set "Blank icon" with SmallIcon size to all rows, when adding them or what? Wasn't like that in VB6, how is it in VB.NET?

View 4 RepliesProgram For Class That Acts Like An Accounting Ledger Or Checkbook Organizer
Jul 3, 2010I am writing a program for class that acts like an accounting ledger or checkbook organizer. There are many things that I can't figure out how to make happen.
First- I need a running total of credits and debits at the bottom of the form. I can't figure out how to get that to display. I tried it, but it just locks up the program.
Second- I put in an error handler for non-numeric input and that works but when I want to clear all fields with the clear button it errors each field for not having an entry. I tried 6 ways to Sunday to accept (""), but it messes up other things.
Third- I want 5 transactions to be visible with the ability to have 7. I have hidden the last two and want them to display when the new transaction button is clicked, but can't find anything in my book that would allow that to happen.

C# - A Style That Activates Depending On Another Style?
Dec 24, 2010I am trying to make a style that only gets applied if the parent element of the element that the style refers to, has another specific style. Kind of like in CSS where you can do ".class1 .class2" to specify that the "class2" theme only applies if it is within an element with the class "class1". I do not wish to use any form of external DLLs or libraries for this task. I want to know if it's possible to implement on my own.
I've tried using MultiTriggers with no luck. I have a style that applies to all TextBlocks. I want the textblock to do the following: If the font-size of the textblock is 11 and the parent element's style is "PinnedSuggestion", set the foreground color to "#FF505050". If the font-size of the textblock is 11 and the parent element's style is "Suggestion", set the foreground color to "#FFCCCCCC". The conditions that I have tried to write to make this work, are as follows (the font-size condition is true, but the other one is not). The conditions are inside a style that applies to all textblocks in general.

Change The Button Style And Button Text Style On Mouse Rollover?
Mar 7, 2009I am creating an application and am very new to VB. I have 4 buttons on my form which is like my applications main menu. I would like that each of the buttons behaves in the following way when there is a mouse rollover: The Button back color is changed from the default to Red The Button text is changed to Blue, Bold, and increases in font size I would also like all the buttons to go back to their initial state when the mouse leaves.
Another thing, instead of me writing code for each of the buttons event handlers (Mouse Hovers, and Mouse Leaves) is there a way I can write this code once, maybe as a function and then always call it for any button that I create from here on so that any new buttons take on this behaviour.

IDE :: How To Make The General Deployment
Jun 13, 2009i successfully deployed one application but some small small issues coming in that...Here i want clarify some common doubts in redistributable components...I created one windows application in VS 2008 with C# as language and SQLServer 2005. I created msi setup application in vs 2008 itself. My application includes 2 third party tools. One is for skin and another is for capture images from different devices like camera, web cam etc...Database i deployed is sqlexpress 2005
Generally i added the following prerequisites:
1. Dot Net Framework 3.5
2. Windows Installer 3.1
3. Crystal Report basic runtime for vs 2008 (x86, x64)
4. SQL Server 2005 Express SP2 (x86)
For all these i have no doubts except 4th one.Other than these prerequisistes my first third party tool(for skin) include Visual C++ 2005 Runtime. For this i tried Visual C++ Runtime included in the VS 2008 prerequisites but not worked. So i downloaded Visual C++ 2005 for x86 and x64 and create the custom prerequisites using "Bootstrapper Manifest Generator" and its working successfully For the second third party ocx component (for live video from devices) they telling the following compenents other than ocx component.
a. MFC Libraries (gdiplus.dll, msvcrt.dll, mfc42.dll)
b. DirectX 9 runtime or better
c. Windows Media format runtime files (they gave wmfdist.exe)
I told the system OS requirement is Windows XP SP2 or Vista. Architecture 32 bit and 64 bit(with conditions)
1. I didnt include the 3 MFC Libraries (gdiplus.dll, msvcrt.dll, mfc42.dll) in my setup application Yes i not included the these dlls. But i didnt get any error up to now. I think XP SP2 included these files. Any problem raises in vista or somthing other machines if i leave these files or these files updated when i installed that Visual C++ 2005 runtime? Because when i search MFC libraries i got the result as visual c++ runtime. Please clear about this and tell the i want to include or not?
2. I didn't include DirectX 9 runtime I dont have any common doubt in this because mostly sp2 inludes directX only. But if i inluded these can you give the latest and best redistribution component download link? I dont know is this component differe 32 bit or 64bit?
3. I didnt include Windows Media format runtime files This also i dint included but not got any issues. But some customer told that grains like coming in the live screen. Is this because of unavailability of these component? For include this i didnt got the download link. But i download the sdk from the following link...
[URL]
I installed and i got the same wmfdist.exe as the third party gave. My doubt here is is this support for vista also .. Any incompatabiliy for 64 bit.? if then can anyone give the 64 bit redistribtuion component download link also.
4. SQL Express 2005 Express 64Bit As this application want to support 64 bit also...i want to include 64 bit express edition. But i think the 64 bit support is express advanced version only. Here my problem is if i download tht i cant create custom prerequisites for sql express because i am not well in this.

.net - Child Type In General Function?
Apr 15, 2010I have a MustInherit Parent class with two Child classes which Inherit from the Parent.How can I use (or Cast) Me in a Parent function as the the child type of that instance?EDIT: My actual goal is to be able to serialize (BinaryFormatter.Serialize(Stream, Object)) either of my child classes. However, "repeating the code" in each child "seems" wrong.
EDIT2: This is my Serialize function. Where should I implement this function? Copying and pasting to each child doesn't seem right, but casting the parent to a child doesn't seem right either.

Copy Protection For General Files
Apr 14, 2012I'm making a program to protect custom game files from being copied as best I can, however there are a couple things I need to account for. Some of them I have, others, I have not been able to find information on. When the files are not in use, I have them fully encrypted and hidden from the lay user through a bunch of other tricks (+s attribute, for example). However, I would also like to prevent copying these files while they are being used by the game - obviously I cannot have them encrypted while the game is attempting to read from them.
This opens up a hole, which I have also tried to deal with, but I know my attempts in this regard are less than thorough:
Stop several known well-known copy programs from operating during operation, that being Windows Explorer, Teracopy, and cmd
Now, the other solution I was thinking of was a filesystemwatcher object scanning the better part of the computer for any copies of these files located outside of the "OK" directory, but I'm a bit skeptical as to whether or not this would be very efficient. Any ways to make copying these files difficult without rendering them unusable to the program.

View 2 RepliesGeneral Info On The INTERFACE Keyword?
Jan 5, 2010If you have a separately declared PUBLIC INTERFACE and then IMPLEMENT that INTERFACE.
1) My general question: Is an INTERFACE simply a means to ensure that a CLASS implements all the methods defined in an interface and to ensure that they can only be implemented once?
I have noticed that a method that IMPLEMENTS an INTERFACE method can still have overloads though. :-)
If so, when combined with INHERITANCE though I believe I can finally see the use for defining an INTERFACE!!
2) Do you have to use an interface when linking to a VB6 project ( is this via Component Object Model or COM ) and if so, do any attibutes need to be applied when doing so?
Here is a code snippet.
creating a PUBLIC INTERFACE outside of any CLASS. I guess this would not normally be done from an OOP point of view?

Jan 20, 2010I am often asked to create a very simple database front-end for friends or family, and the structure of the database (and application) is usually very similar.Right now I am always creating a class that handles all database interactions with some shared functions. For example, there's a function to run a general query and return a table, a function to save/load various items (depending on the application of course). The point is: the code is nearly always the same except for some slight variations.
