VS 2008 General Syntax Question: Hiding Properties?
Apr 21, 2011
I have a (pretty large, 1000 lines or so) class with a lot of properties, both regular,overridden and overloadd properties. I currently add this in front of the property to hide it from the designer:<Browsable(False), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)>This is all great, but it adds quite some lines to my project. How can I specify, for my class or project, that it should add the above settings to all?Or even better: set the above settings for a block of code instead of a single property.

I have made a Windows Service program called InvCheckService.exe. I am passing the working folder using the Services Property for this program. I am putting the parameter "D:Inv" into the "Start Parameters:" textbox.In my program I am getting 1 parameter. Its is D:MyServicesInvCheckService.exe which is where I ran the InstallUtil.exe from.
Here is the code for the OnStart Subroutine:
Protected Overrides Sub OnStart(ByVal args() As String)
Dim parms() As String = Environment.GetCommandLineArgs()
Dim msg As String = ""

I 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.

I'm looking at implementing a piece of software I've created into a new environment. It is currently accessed via network share by users who have full administrative permissions on their user accounts. These same users will have their accounts locked down excessively. I am wanting to consider now before any changes have been made, any code changes I will need to make as my application makes use of a lot of features that admin users take for granted such as registry editing. My program is running through the .net 3.5 framework and is being accessed on XP machines.

I saw an application for cashier system in a certain store. I noticed that while the application was running, the window form of their application occupies the entire screen and the windows taskbar seems to be hidden. I'm just curious how did they hide the windows taskbar? Do they hide the taskbar in a manual settings on their computer before the application was launched? If not, how did they make their application capable of hiding the taskbar? Please put a detail code if applicable. I just want to know how to hide the taskbar when you launch the application and put it back when you exits the application as well.

I have a form that is the main form.I don't want it to show when it loads, but when I do Me.Hide() in the Form_Load event, it flickers visible before it hides. Because before I made this form the main form, the one I was using previously didn't flicker.

I have a data grid on my form with 6 columns. 5 of the 6 are combobox fields. When just looking at the datagrid all the drop down buttons on the left really clutter up the grid. Does anyone know a way to hide the drop down button on the combo box until the time the user actually clicks in the cell. I have tried changing the style to flat which helps but I would rather it wasn't visible at all until the user is actually in the cell.

It is times like these that I miss the old VB6 language I wish I could hide the current forn and show another form which - this is the important thing - to be on the same level that the previous form was . You see , I used to use this code :
Me.Hide Form2.Show However , sometimes in VB .NET this does not work the way I want it to . You see , the current form does get hidden and Form2 is shown indeed ; however , Form2 is shown somewhere in the background . If there are other programs opened at that time , then Form2 is shown behind all those programs , that's what I mean by saying I want it to be shown in the same level as the previous form was the only way out , I found , was to reverse the code :
Form2.Show Me.Hide In this way Form2 is successfully shown right where the previous form was shown (above the other programs) but in some cases this also is not pleasant because it might take some time for Form2 to load while at the same time the previous form is still visible on the screen and therefore for a slight time both forms are shown one over the other , which is surely not nice . That's why I still want to first hide the first form and later show Form2 .

I'm having an issue with my app where IE will get brought to the front of the screen when I am switching between forms. Basically I have a form with the man menu which consist of a few command buttons that will start up another form once a user clicks on the button. I do not want the users loading up multiple forms in my application, so once they load one form I end up hiding the main form. So my code looks as shown below when a button is clicked.

Working with a form that has a menu, toolstrip and Crystal Viewer control. I cannot seem to get the viewer to maximize properly without hiding the toolbar of the Crystal Control behind the menu and toolstrip. I've played with the options of Dock and Alignment, as well as autosize and I just can't get it to work.So do I need to handle the sizing myself to do this and position the control where I need it?

This is going out to the forum at large. Where can I find the most complete explanation of the use of the DataGridView control in VB.Net? Any publication, or on-line reference except MSDN, please. I can never make heads or tales of MSDN.
Likewise, a complete tutorial on the usage of XML within the .Net Framework would be appreciated. Same qualifications as above.

i 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.

whipped up this code real quick which uses a ThreadPool on Form Load to iterate through my subnet and tell me if there's a device communicating at each IP address.
some questions: Why am I able to update BOTH my label at the top AND the listbox, but I'm only using an .Invoke on the Listbox?How can I know how many threads are currently being used while that is executing?
What does the SyncLock do?I'm aware some people don't like the use of Application.DoEvents(). Is it ok to be using it in this instance or is there a better practice?For those wanting to try it out, drag a Label and a Listbox to a new form. Label is called "currentIPTextbox", Listbox is default name.

I 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.

I'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.

If 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?

Implements Whatever
