I have a problem in installing Internet Printer programmatically with username and password.
I am able to install Printer using the following command:
rundll32 printui.dll,PrintUIEntry /if /b "Printername" /f %windir%\inf\ntprint.inf /r "https://username:email@example.com/printers/Printername"; /m "HP Color LaserJet 2500 PS Class Driver"
But Windows is not recognizing credentials. Hence I cant Print. I get Access denied message.
Is there any option to achieve this programmatically?
Any help will be greatly appreciated.
I am using a dial up connection for net connectivity. The net connectivity is established through a GSM GPRS USB Modem connected to a PC Com Port.
I am using rasdial command to connect to Internet.
Once connected, I am pinging my server periodically to check and ensure that net connectivity is in place.
When Ping test fails (this happens irregularly after 2 hrs, 3 hrs or sometimes aftr 5 hrs also), I try to disconnect the established connection using rasdial disconnect command - however this is not successful every time a ping fails for reasons not known to me. (somewhere I read that rasdial disconnect command will not work after disconnection).
Given the above scenario, i am not able to reconnect or reestablish the net connectivity unless and until I restart the PC and this is not a possible option as my application is running and this will not allow PC restart.
Want recommendations /advise as to how to reconnect to a dial up connection after it is disconnected ? What are the possible ways and means for this.
I want to create a virtual serial port on Windows10 using VirtualSerial2 sample but first I should convert it to KMDF. When I look at the functions in the sample I saw that some of them apply to KMDF or UMDF only. Why are they used in the same driver? How can I learn that which one to include?
I have a Dell XPS system with Windows 10. It has four SATA ports. Everything is going fine except for one thing: the DVD drive.
When I first got it earlier this year, the drive, although not used extensively, worked fine. I was able to install a few things from it. Shortly thereafter, I installed two more HDDs. All four SATA ports are now full. I can see and use the three HDDs just fine but not the DVD drive. On a few occasions, the DVD drive shows up and I can use it like normal. Other times, not! The BIOS recognizes the drive, just not Windows (using either Windows Explorer or Disk Management).
So my question is, would having all four SATA ports full be the cause of any of this?
I went out to Dell's site and ran their diagnostic program on my machine. It had two recommendations: one for the WiFi adapter, and the other for the BIOS. I don't use WiFi, so I opted for the BIOS update. Since installing, the DVD drive has remained intact.

Hi! I'm sure this is without question a super beginner question, but I feel like I need to make an informed decision because I don't know how much it matters.
I need to know what is the best budget laptop for a computer programming college student, that can handle whatever is required of the course. My old laptop broke and I need to know how important a new one's specs are for this course. Any information would be helpful please.
If you're planning to use it for normal purposes like using MS OFFICE and other software. It's very important to choose your processor and RAM. And if you're into gaming, please consider getting a good GPU as well. HP Recently released this laptop which I think is good for you.
Hi Ivan, while buying a laptop especially for Programming ( As you are a Programming Student) You should see below these specifications:
1) RAM - Memory is very important as all applications use memory to store temporary variables. 4GB is Good and it can increase up to 16GB.
2)Processor: Cpu plays a major role in speed as it processes millions of bits in a second, So Ideally i5 or i7 processor is the good choice.
Extra Features you should look for -
1) Graphic Card
2) Battery Backup
You can check out both of them, they have good reviews and specifications.
One thing you didn't say and it has a bigger impact to the performance is the use of an good SSD.
About your tips...
I have worked long with DELL Latitude (several models) and I was very happy with them. They have the option of "big capacity" battery which gave me the possibility to work the whole day without having to plug the power supply.
I would like to know if the following device driver is possible in Windows 10:
A driver that receives a notification whenever a user mode process is created, and can then load a user-specified user mode DLL into that process before any user mode code in the process executes (including TLS callbacks.)
I'm not asking for code or how to write it, I'm only asking if the facilities exist in Windows 10 to make such a driver possible.
The difficult we do right away...
...the impossible takes slightly longer.
Let me point out that all of the user mode ways of doing this are not acceptable because I need the DLL to be injected before any user code executes in the target process, including TLS callbacks.
Have you experimented with the CreateProcess function[^] and the DEBUG_PROCESS and DEBUG_ONLY_THIS_PROCESS flags combined with CREATE_SUSPENDED? This should give you access to the process before anything as executed including TLS callbacks.
Is there a specific reason why you believe that you need to use a device driver? Are you trying to avoid the TLS callbacks and process initialization for a single process or system-wide?
From usermode you can use the Application Compatibility Toolkit[^] to load a DLL into any process system-wide immediately after kernel32/user32 is loaded and before any usermode code has executed.
I'm looking to implement something very much like this: API Monitor[^]
Yes I have tried CreateProcess with DEBUG_PROCESS and CREATE_SUSPENDED, but that doesn't work for my purposes, and here's why:
Once my hook DLL is inside a process, I need it to be injected into all child processes as well. This means hooking any API's that create processes. I have found that some programs use the DEBUG_PROCESS and CREATE_SUSPENDED trick as well. And I haven't yet figured out a way to inject my DLL and return the child process to the calling program in the state that it expects it to be in. What usually happens is a crash of the child process, because the calling program couldn't do what it wanted to do with the child process before any user code executed. Did you follow that?
That is why I think I need a driver to accomplish this, because I have tried every user-mode way of doing it and just couldn't make it work.

...the impossible takes slightly longer.
That's an impressive body of work by Rohitab Batra. However I see a lot of problems with that software suite. The XML files that contain the API structs, interface and other definitions will not match on some operating systems... depending on update/patch level. If you ran his software on 10,000 computers 'in the wild' you would find that a certain percentage of those may not completely match his XML descriptions. It would be much better if he downloaded symbols from the Microsoft symbol server and used the Debug Interface Access SDK[^] to extract that data from the PDB symbol files.
It is still an impressive piece of software and looks very useful for malware analysis and other debugging scenarios.
Microsoft has made some private symbols available to some ISV and partner programs after signing NDA and some special agreements. There is also the 'https://codepremium.msdn.microsoft.com/symbols' private symbol server made available through the shared source initiative[^].
I took a brief look at his software package and was immediately impressed. It would be a great tool for sandbox automated malware analysis. However it is severely lacking in one single area... the function signatures in his XML files will not match on all operating systems. To make matters worse... he does't even mention which OS/Patch level those definitions match.
If he would author a tool for generating those function and type definitions using the Debug Interface Access SDK[^] it would be a much better tool. It would allow his software to perfectly match the machine it is running on regardless of Update/Patch level.
