One of my application is taking a lot of time on Windows 7 compared to XP. What application basically does is it creates some PDF files reads the content and emits on a form and then deletes the files. I ran ANT profiler on both XP and Win 7, and i could notice some differences. On win 7 some CAS related methods are widely called and those method calls were missing on XP.. Is this the reason ? If someone has faced similar issues,
View 4 RepliesI recently did a clean install of Windows 7 Home Premium and a reinstall of Visual Studio Professional 2008. I can't find the Framework Configuration anywhere. I have looked on the Start Menu and in the Control Panel and in Administrative tools. I need to find it so I can fully trust the network where my projects are located.
View 3 RepliesThis program is a small ADOX database with a single data entry Form. Originally written in VB 2005, it was copied into the VB 2008 Project folder. Opening the file in the IDE, it went through the Conversion process, nevertheless, because of the following error detailed below, the program will not accept any changes.
Error List: Warning 1 Unable to find manifest signing certificate in the certificate store. AppointmentsMissed (<the project's name) Under Security in the project's Properties Window these suggestions are made: Visual Studio was unable to determine the Code Access Security (CAS) permissions that are applicable to your project. The most likely cause is that your project references a strongly-named assembly that defines custom permissions, but that is not properly installed in the global assembly cache (GAC).
To correct this, try the following: 1. Ensure that any custom permissions defining assemblies referenced by your project have been properly installed to the GAC. If any of these assemblies have been rebuilt or have had their version numbers modified, you must install the new assemblies in the GAC. 2. Restart Visual Studio.
I have some sorce codes on my comp. and i am employing a few s/w guys for coding at my office i would like to know what type of security softwares / hardware i should install so that the employees do not copy my source codes and i would like to give them access to net but not to attach my source code. i have searched on net ...but as i lack the basics of this i am asking the favour from all u experts. most of the search has sent me to the links for antivirus or antispyware....and like wise.
View 6 RepliesI am not sure about the semantic of "ApplicationDirectory" membership condition. I am trying to use it in the .NET Framework 2.0 configuration tool. The tool's explanation to it is as below:
The Application Directory membership condition is true for all assemblies in the same directory or in a child directory of the running application. Assemblies that meet this membership condition will be granted the permissions associated with this code group.All the other membership conditions such as strong name, hash, allow me to input some criterias, only the Application Directory has not. So how to use it?

View 1 RepliesI'm creating a windows application form in vs 2005 for a client.. It's a data-tracking application. I have a few questions.The client wants a logon screen to be added into the application (at least any way or method that'll ensure that security was applied). My question in regards to this topic would be; Is it necessary to create a logon screen (or even a user authorization) for a windows form? I realize that in a webform project, security should always be considered and should be applied in all areas. Although with a windows form, I thought you can authorize who can gain access to the application by defining which workstations to install the final production release of the application (when its time to deploy the file). Is this correct?
My next question is, what is the best method to exporting data from EXCEL to SQL tables? I have many Excel files that I'd like to take portions of data from each file and insert them to there proper table.
The last question is about deploying a windows form application. As you can tell, I don't have much experience when it comes to developing Windows Form projects. Anyways back to the topic, When deploying a project, does it provide a .EXE file (installation package) to install the application on the workstation? Or is it a .EXE file of the application, where you can run it and no need to install anything?
I'm writing a backup program for personal (for the moment at least) use.
For some directories (network directories / protected directories) credentials are needed to access them.
I can setup different jobs in the program to run at specific times.
These jobs are stored in an XML file.
I want to also store the usernames and passwords which the jobs will need.
What and where would be the best way to store these?
Changing permissions on the directories is not an option.
I am trying to control the security board using the Windows Firewall which connects to my server that was made in VB.Net. My only problem is when I open the Windows Firewall my server crashes. It also displays this error: "Error, win%fir%90y4e does not support this server. upgrade you version of Winsock.". So I upgraded myself to the latest Winsock that there is out there. After doing so I try again and my server still crashes, but this time with a different error. The error this time was the following: "Error, no client is available for win%fir%90y4e. try again later.". What do I do?

View 15 RepliesI have a treeview control which is being used to browse various folder on the users system drive. It can also be set up to connect network folders using UNC paths e.g "serverfiles". At the moment I'm getting a list of Directories by using My.Computer.FileSystem.GetDirectories however this obviously fails when the folder is password protected.
Is there a way that I can get Windows to open the credentials dialog as you would see in Windows Explorer and deal with the credentials side so then the user name & password is cached as well?
I need to implement, Controls Based Security in a Windows Forms Application using VB.NET. I tried google but did not get anything much to work with.
I would like if someone, could suggest some books or tutorials.
I made a password protected program, but I wanted to make a reset password via security code. I made this, but it will not work for some reason. It seems like it'll work for the first time, but then when you try to set the password, it stills shows that the password is there and when I go into the reset password form and do it again, but then it say its incorrect.

Trying to read key "HKLMSOFTWAREPoliciesMicrosoftWindowsWindowsU pdateAU" value "AUOptions" and get the following : A first chance exception of type 'System.Security.SecurityException' occurred in mscorlib.dll Error occurs in ReadRegistry key SOFTWAREPoliciesMicrosoftWindowsWindowsUpdate AU : Requested registry access is not allowed. This occurs in my vb.net application when application is run under an account called OPER in the USERS group. The application :
1/is on my PC's hard drive, its not a web app or on a network share
2/is launched via a desktop click
3/ has a manifest specifying executionlevel "AsInvoker"
It does not occur when the Application is run as an Administrator. It does not occur if I read the value with a non .NET program when logged in as OPER whch makes me think it is a .NET problem not a registry permissions problem. Examining "Effective Permissions" shows that my OPER login has query value permission.I need the application to be able to read the key like the non .NET application while running at USERS level.

View 7 RepliesI've got this program I'm working on in VisStudio2008. Basically, it accepts a password and executes an Access 2003 database using the Access 2003 runtime. I've got the thing looking up a password and all is good, but there's one problem those annoying Access 2003 and higher warnings about unsafe macros. Does anyone know a way to make sure those don't show up when the program starts?My client has a database that someone else wrote for her. She's not at a point where she could have it rewritten (believe me, I've tried to talk her into that). So I have to stay in Access but it's not very professional to have those warnings come up.
View 5 RepliesI need some help in the creation of a program to generate a security code based on the current date.

I would like to create a small program that sits in the system tray with this code displayed. The code will always need to be 6 characters, so I might need to pad it with zeros.
