I designed an application in vb.net 2005 while using Administrator account on vista.After compiling the application it start requesting for elevation during startup.I will like to prevent this, because the customer is complaning
View 2 RepliesHas anyone managed to get administration rights through the UAC without restarting the application or embedding a manifest file?
I'd like to write to some files that only administrators can modify, without relying to another elevated application. Is it possible to impersonate an administrator previously calling with some native API the UAC prompt?
I guess this is not possible and I'll have to use an external tool with elevated rights, but I'm asking just in case.
EDIT: I know there are some other similar questions around, but since they do not cover the topic of impersonation (as fas as I've seen), nor some possible native call to the UAC prompt I decided to give a new thread a go...
I have created a 2008 Visual Basic.NET application I'm using on Windows 7 that requires elevation. In myapplication I used the UAC manifest in VS 2008 to makere elevation. that works fine with a regular 2008 VB.NET form and will remember the form postion.On my application (really just a form) that requires elevation it will not save the position and always starts in the upper left of the screenDoes anyone know a way around this on an application created that requires elevation
View 2 RepliesWe have a construction company and I am designing a program in Visual basics for it. This program is intended to be installed only on the computers in our office ( its not going to be distributed ). There is always a risk that one of our employees will take our software and distribute it . Is there anyway to prevent this. If not how can we make this as difficult as possible?
View 1 RepliesI have an application that creates files at certain directories, deploys them and then removes them when neccessary. Under Windows Vista and 7, access for my program to carry out such commands are denied because UAC is blocking it.Now i am NOT using Visual Studio, i am using SharpDevelop and my project is a Windows Form. How can i prompt the user with the UAC dialogue so my application can acquire UAC elevation and carry out its tasks?I would also like to point out that everything works perfectly when UAC is either turned off or the user runs my program with Administrator Rights.
View 7 RepliesI have an ActiveX EXE that is compiled with VB6, unfortunately because it exposes an ActiveX interface it refuses to run unless i embedd a manifest file into it requesting elevation priviliges of administrator.This in turn has the side effect of VISTA prompting the user to logon as administrator each time they run the application.The admin on site has already refused to disable UAC.Is there any way for either our application or the administrator to auto-elevate the program on the domain?
View 4 RepliesMy work is, I have a DEM file and header file of it.Now, I want to display the elevation value from the DEM file of the given Longitude and Latitude.And, I worked on it before,Where I could get the elevation value with the resolution matrix of 6000x4800 and I can able to read the elevation value.But, now I want to modify in such a way that I should read the elevation values from the DEM file with the resolution matrix of 11x11.So, kindly guide me in getting the elevation value with resolution of 11x11 matrix.The code I have used before to display the elevation value with resolution of 6000x4800 are:
[Code]...
I need to display or get the elevation value of a given latitude and longitude from the DEM file in 11x11 matrix array.Actually I have a DEM file and corresponding HDR file of it.And, the DEM file is 6000x4800 Matrix with 57600000 data's.Now, I worked with some codes where I can able to get the elevation of a Given latitude and longitude.But, When I Zoom IN or OUT,the Latitude and Longitude values changes so,when I pass the changed latitude and Longitude value,I could not able to get the elevation value.The reason is,
In the 6000x4800 matrix the Resolution of the X and Y is large,so when we Zoom IN or OUT the resolution changes and could not display the elevation value.But, where as if we get the elevation values in 11x11 matrix array,since it has 121 data's only, the resolution value will be small and even when we Zoom IN or OUT and pass the changed Latitude and Longitude, we could able to get the elevation.[code]....

Is there a way to prevent the VB .NET editor from saving the project whenever IT LIKES TO ? It very annoying ; it so stupid that it saves things that I don't want to and that I didn't ask it to do .If I add a form and then close the editor , when I open the project again , that form is still there though I DIDN'T save it !If I change a declaration from Friend to Public and close the editor without saving , then when I open again the project , my modified code remains modified , though I DID NOT save it !Today I realized that if I delete some controls of a form and then close the Editor , then when I reopen it , the controls are missing for good ! It saved that modification by itself !
View 3 RepliesI've completed an assignment that requires me to search through two listboxes for a particular number.If the number is found, the text on a label changes to a dollar amount, otherwise a message box is displayed letting the user know that the requested number cannot be found.It works well enough, searches through the listboxes, finds the number, and displays the message box when it can't be found.However, the message box shows repeatedly up to five times.After the user clicks "OK" on the fifth appearance, the program crashed and displays the follow message."Invalid Argument = Value of '5' is not valid for 'index'.Parameter name: index."I don't know what's causing this, or how to fix it.I do use the index as a counter at a portion of the program...but I'm not sure where I went wrong with it.[code]Also there are five items in the second listbox...probably has something to do with it.

View 3 RepliesThe original post provoked more responses than I anticipated. Therefore I have tried to draw them together with this post.There appear to be several schools of thought on this issue.One holds that I should not release time-bombed software because it is illegal.
Suppose I include code that often randomly checks if the user is registered and then puts up a message and shuts down the program if a check fails - rather like an improved nag screen. Would this be regarded as illegal?One holds that I should not worry about it because the pirates wouldn't buy my software anyway.
Maybe, but there's no fun in that.One holds that it is a waste of time because it is impossible to protect 100%.Maybe, but once again no fun.My view was that an honest user buying from my site would get a genuine copy. If a dishonest user got a harmful copy and lost the lot then I couldn't care less.Reed Kimble pointed out the existence of "fake sellers" who could cause harm by selling honest users a dishonest copy.This is a problem that I had not thought of and it poses a dilemma.
If I do include protection, then how do I distinguish between and honest user and a dishonest one? They will both be caught by the protection.should I not include any protection at all so that the honest user doesn't lose out, and just accept that the dishonest one gets away with it?Or nail the pirate and accept the honest loser as collateral damage?

What's the best way to prevent javascript injections in a VB.NET Web Application? Is there some way of disabling javascript on the pageload event?Recently, part of the security plan for our vb.net product was to simply disable buttons on the page that weren't available to the specific user. However, I informed the guy who thought of the idea that typing
javascript:alert(document.getElementById("Button1").disabled="")
in the address bar would re-enable the button.
Update:Aside from validating user input, how can I protect the website from being toyed with from the address bar?

View 1 RepliesI often face the following problem : when I have a form with lots of controls on it (100 , 200 etc) and I change the name of a control , the IDE goes slow for a few seconds . This is very annoying when I have to change the name to a lot of controls . I believe this is happening because the IDE checks the forms , the code etc to see if there any problem after (re)naming the controls . Of course this is welcome because it prevents a lot of problems , but at the same time it creates some serious problems as well . Thus , I wonder , is there any way I could prevent the IDE from checking all those things in order not to reduce it's speed ? Of course I am talking temporarily . I believe that what I gain by letting it check after every name-changing , I also gain it if I only let it check once (at the end of the name-changing process) .
