Feb 16, 2011I have a sulution consisting of aout 30 projects, where 8 of tehm are deployment projects. Currently, when I want to debug the winforms app, I press "start debugging", and wait for about 15 minutes for the solution to be built, and also the deployment projects to be built and packed. The solution itself is built in about 2 minutes, the rest of the time is for the deployment projects.So, my question, is there a way to make the setup in visual studio so that only the code projects are built and the deployment projects to be built manually when needed?

[2005] - User Controls - Prevent Them From Showing Up In The Toolbox
Feb 1, 2009I have created a series of custom user controls for a wizard interface that I am making. Each user control represents one step in the wizard and really shouldn't be used outside of the wizard. The thing that is bugging me is that each wizard step user control shows up in the toolbox of components to insert into a form.
Is it possible to hide a user control from the toolbox? Better yet is it possible to hide a user control from other classes not in the same namespace of an assembly? Is this a good approach or should I think of a different approach?

Add To TextBox, Prevent Scrolling?
Mar 25, 2009I have a textbox to which text is continuously appended (every second new status data at the end).I would like to act it as follows:- When the cursor is positioned at the end: Stay at the end, scroll the textbox (text disappearing at the top).- When the cursor is positioned somewhere else (not at the end): Stay exactly there, don't move the cursor, don't scroll, don't change the top line of the textbox.This seems to be surprisingly difficult (tried quite several ways).This is how far i came:

Deployment :: What To Prevent Anyone From Using DLLs
Feb 2, 2010You developing a application named "DemoSoft" which is going to be a shareware or Premium, you use different DLL's in this project and some DLL's are owned by you, they are very useful and valuable, you are selling this software and are charging the customer for what the software does but since this software uses one of your Valuable DLL, actually few functions from it you have to deploy it and cannot additionally charge for the whole dll. since that would be unwize.now i want to ask what can you do so that This DLL in "DemoSoft" cannot be exploited, meaning end user could use my software but if some thief tries to use my supplied DLL in one of his own app he is unable to do it, in simple terms DLL should work only and only with DemoSoft.
View 5 RepliesDetect Changes To Registry Prevent Changes
Dec 29, 2009How can you detect when the registry is changed? Furthermore, how can you prevent changes to the system registry? I want to create a security tool, but can't seem to find this anywhere.This is in vb.net.I know the registry is stored as files on your computer somewhere, but I have no clue where it is stored, though I could probably use a FileSystemWatcher component to check it.Then, for prevention, would simply duplicating the registry files and rolling back the changes work?

Mar 20, 2012We know a tolower function will turn all A to a How to turn all à to a.The purpose is I am creating ids for databases and id need to be unique.

The same way ě should become e.
Basically I would use utf8_unicode collation on my databases. Letters that count as the same letter under that collation should map to the same character under this function.I need to make sure that all other east asian characers are not affected in anyway.

How To Prevent Program Being Started Twice
Apr 8, 2010I have a small problem with my application. When the system starts up, the program starts with it, but runs hidden (registry key with paremeter). The program also has a GUI.I want it so that when the user clicks the desktop icon, it does not start a second instance of the executable, but instead reveals the currently running background process. Is that possible?i.e. when the application is started with the "-startup" paremeter, it loads a hidden form2, and closes form1. When the desktop icon is clicked, it loads form1, while form2 remains hidden.

Sep 12, 2011I've got this little 'Sticky Notes' type of application and the form I have is a borderless, taskbarless form and for Windows 2000 compatability I'm using VS 2008 and targeting the 2.0 framework. One of the hurdles I have is that in XP, Vista & 7 when you click the Show Desktop button all of my note's windows get minimized and without a taskbar icon, it's not easy to get them back (at least not for a normal user) & I'm looking for a way to either right after the windows minimize I just have them all show again or if I can skip the minimizing message in the wndproc altogether

Prevent A Keypress In Another Application?
Mar 17, 2011We have 2 apps that we display at once for data entry. 1 taking up the left side of the screen, and 1 taking up the right side.
1 of those apps is the data entry application. The other app is for viewing scanned info. But they can't talk to each other directly.
So I'm creating a tool that runs in the background to intercept certain keys.
I want to be able to capture keys such of Ctrl + Home, Ctrl + Page Up, etc from the data entry application, and send it to the scanned image to rotate it or zoom, etc.
I believe I can do most of it, except 1 part.
Right now if I did Ctrl + PageUp, it will send the key press to both apps. How do I prevent a keypress from the originating application?
