Hi,

I have two strings, one of which is named  "strIn". The other is a property on a "leaf" - for brevity, I'll call this one strOut except in my code.

I'm trying to see if strOut begins with strIn. That is, if strOut is "KAREN" and strIn is "KAR", then find() should return 0. However, it instead returns -1

Here is my code:

string bTreeClass::Search(string strIn)
{
	string strOut;

	// Binary trees are organized so that the lower leaf is on the left
	// Start with the root leaf(current leaf is the root leaf
	LeafClass *currentLeaf = rootLeaf;
	//	Loop until match found or current leaf has no links
	while (true)
	{
		int find = currentLeaf->GetString().find(strIn);
		//	If strIn is in currentLeaf's string
		if (currentLeaf->GetString().find(strIn) == 0)
			// Match found
			// Exit Loop
			break;
		//	 Else if search data is less than current leaf data
		else if (strIn.compare(currentLeaf->GetString()) < 0) {
			//	If current leaf does not have a left node
				if (currentLeaf->GetLeftLink() == nullptr)
					//	Match failed
					//	Exit loop
					break;
			//	Else current leaf does have a left node
				else
					//	Advance current leaf to current leaf's left node
					currentLeaf = currentLeaf->GetLeftLink();
				//	End if
			}
		// Else (search data is greater than current leaf data)
		else {
			//	If current leaf does not have a right node
			 if (currentLeaf->GetRightLink() == nullptr)
					//	Match failed
					//	Exit loop
					break;
				//	Else current leaf does have a right node
				else
					//	Advance current leaf to current leaf's right node
					currentLeaf = currentLeaf->GetRightLink();
				//	End if
			//	End if
			}
		//	End loop
		}
	strOut = currentLeaf->GetString();
	return strOut;
}

I'm returning the datetaken attribute from the GetDetailsOf method from jpg files in a folder, but when I do a DateTime.parse conversion against the returned string I get an error saying: String was not recognized as a valid datetime. I displayed the string in a textbox and it is: 9/‎30/‎2016 ‏‎5:24 PM, which is obviously a valid datetime. I did a test by inserting that date as a literal in a test string and the conversion worked fine against the test string. Anybody had experience with datetime attributes returned as strings from getdetailsof method?

pertinent code snippets:

If String.Compare(Microsoft.VisualBasic.Right(fullfileName, 3), "jpg", True) = 0 Then
                        lastslashpos = fullfileName.LastIndexOf("\")
                        filename = fullfileName.Substring(lastslashpos + 1)
                        attrstring = GetAttributes(sourceDirectory, filename) ' Calling getdetailsof here
                        TextBox1.AppendText(vbNewLine & attrstring) 'Here's where I looked at the date taken returned, good datetime 
                        datetaken = DateTime.Parse(attrstring) 'FAILS HERE
                        datetakenlist.Add(New KeyValuePair(Of Date, String)(datetaken, filename))
                    End If

Hi all,

Can i get any help on how to get the CDC serial driver for windows server 2012 r2.  When I connect my hardware to Windows 7/10, then the corresponding USB-Serial driver gets installed and my device is getting listed(COM37) under Ports of Device Manager.

But in windows server 2012 r2, it is getting detected as CDC serial in device manager, but the driver is not being installed. So the COM port is not being shown. Where can i get the CDC driver for windows server 2012, so that I can use it as COM port?

How can i proceed? Any suggestions.

Thanks.

Hi All,

i'm working on a platform for which i would like standard user to change the IP Address of the device. From my C# application I'm using the WMI interface, requesting settings from Win32_NetworkAdapterConfiguration class, and this works like a charm when application runs with Administrator privileges (based on this project https://github.com/NitroAMD/IPv4NICSettingsTool).

For my system use case, the device auto logon as a lambda user with no rights and my app is launched (using the shell Launcher of WES 8). So this app doesn't have any Administrator privileges and this is a main problem when trying to access the network interface configuration. I don't want lambda user to enter any user accounts name or password to perform the network configuration.

So is their any GPO or system settings that could allows my application to perform those network configuration operations ?

Hello,

I have added above keys in my app.Config files. I want to loop through these nodes to capture URL,FileName & Destination for each node.
Is there any easy way of doing this?

I'm testing a 32-bit VC++ application with LARGE_ADDRESS_AWARE turned on, and I want to test when memory is allocated top-down in the address space.  I set the Registry DWORD value AllocationPreference to 0x100000 as documented in MSDN.  (Full path is HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/Session Manager/Memory Management).  Allocations still happen bottom-up.  My C++ code is trivial:

   for (int i = 0; i < 96; i++) printf ("p=%p\n", malloc (1024 * 1024 * 32));

The output shows ascending addresses.  If I run the same program on Windows 7 x64, also with the Registry value set, then allocations happen top-down - descending addresses.

Is that Registry value no longer supported in Windows 10?

Hi,

I am working onIFileOpenDialog/IFileDialog interfaces using MSDN example shown in

https://github.com/Microsoft/Windows-classic-samples/tree/master/Samples/Win7Samples/winui/shell/appplatform/commonfiledialog

In the fileDialog there is an icon in upper right corner to choose

    View Context which contains ‘Extra Large Icon’, ‘Large Icon’, ‘Medium Icon’, etc.

I tried to make fileDialog openalways with‘Medium Icon’, for instance

I made two attemptsFirst attempt was below,

////////////////////////////////////////////55555
	 IExplorerBrowser *peb;
         hr = pfd->QueryInterface(IID_PPV_ARGS(&peb));
	 FOLDERSETTINGS *pfs;
	 pfs->ViewMode = (UINT)2;
	 pfs->fFlags = 0;
	 peb->SetFolderSettings(pfs);   ////////????????
	 peb->Release();
////////////////////////////////////////////////5555555

The second attempt was below

/////////////////////////////////////////////////6666666
	 IFolderView *pfv;
	 hr = pfd->QueryInterface(IID_PPV_ARGS(&pfv));
	 hr = pfv->SetCurrentViewMode(FVM_SMALLICON);  // FVM_TILE);///////??????
	 pfv->Release();
///////////////////////////////////////////////////666666

In both cases the code compiles and links OK.

But when I execute the code it stops at

 First case:

       peb->SetFolderSettings(pfs);   ////////????????

 Second case,

       hr = pfv->SetCurrentViewMode(FVM_SMALLICON); // FVM_TILE);///////??????

The complete code which includes these attemps is listed below.

I would appreciate your help as always, please

I need to have an interface pointer for IStream returned by SHCreateMemStream() which bytes do not contain 0x00 (don't ask why, just assume this as a fact). That is, there must be no 0x00AABBCC, 0xAA00BBCC, 0xAABB00CC or 0xAABBCC00 values returned.

How can I take control of it? When I release some pointer allocated previously which has zero byte, new allocation returns it to me again. I've found only one thing that influences it — e.g. showing File[Open/Save]Dialog with use of Co(Un)Initialize, which makes some memory reordiring, so the IStream pointer returned after that process have no 0x00 in the most significant byte. But of course it is not a solution when you need to occasionally create several interface pointers — that dialog mustn't be shown all times, or even it just not needed to be shown in time when pointers are allocated.

If I fall I will arise on my way to paradise

Hi,

I work with the windows explorer using

ShellExecute(ViewWindow, "open", szFolder1, nullptr, nullptr, SW_SHOW);

I am wondering if it is possible:

When I click on a file like “abc.bmp”, for example, I like to get the name and path of that file.

Thank you for your help.

Hi all,

     We want to access a share point created in localhost by a particular hostname which is not the same as the true hostname. For example, we want to access \\fileserver\sharepoint, where "sharepoint" is the local share point, but "fileserver" is not the true server name. so we set the windows host file and add a new line in the end:

127.0.0.1 fileserver

     However, when we access the share point by windows explore, a prompt for username and password is poped. But no matter what account and password is input, it always prompt that the password is not correct. when we use 127.0.0.1 or the true server name or localhost, we can access the share point directly without username and password input.

     We test this in Win7, win8 and win10. But it all need to input username and password.

     How can we access a local share point without a particular hostname name without username and password input?

     Thank you very much!

Hi

Several years ago I wrote a Visual Basic program in Visual Studio Express 2008.  I used DirectX for sound playback and that worked just fine.  I have purchased a Windows 10 machine and tried to run that application on it and got numerous error messages.

I installed Visual Studio 2015 on it and loaded my code up on that new machine.  

I previously asked for some assistance in this thread and we were able to:

1)  Install the Windows 10 SDK

2)  Add the Reference to Microsoft.Visual.C

Since this is a new error, the moderator suggested asking the follow up question as a new post.

When the program is run in Debug mode and x86, I get two pop up with this error below.  If I click OK to each, the program will run.  

Managed Debugging Assistant 'LoaderLock' has detected a problem in 'path to my app.vshost.exe'.

Additional information: DLL 'C:\WINDOWS\assembly\GAC\Microsoft.DirectX\1.0.2902.0__31bf3856ad364e35\Microsoft.DirectX.dll' is attempting managed execution inside OS Loader lock. Do not attempt to run managed code inside a DllMain or image initialization function since doing so can cause the application to hang.

I clearly need to resolve that error if I am going to be able to run it and compile it for use.  However, I'm a bit stumped, being a novice with VB with all the changes.

What the program does is read the input from a game pad controller, in this case a Microsoft XBOX Controller for Windows.  When a certain button is pressed, a random sound file is played from a specified folder for that button.

Hello Microsoft,

I am building a software KVM switch (to control multiple machines from a single machine mouse/keyboard, similar to ShareMouse, check it out if you're not familiar) and I ran into a brick wall let me explain:

My program needs to switch the control over network from the machine I am using(computer A) to the other machine(computer B) when the mouse cursor would exit from my desktop(computer A) and "magically" reappear on the other machine(computer B) while I am still using the computer A. In order for me to implement this feature, when the program reaches this state I need to be able to block all keyboard and mouse events from reaching to windows(except to my program) while at the same time be able to read all the keyboard/mouse events in my program(on computer A) so I can send them over network to computer B and dispatch them on that machine.

I found only one solution to block the input events using the C++ windows API exposed method BlockInput() which under Administrator rights works perfect, however when I globally block all the input, I can't read it in my program any more until I unblock it again:

"When input is blocked, real physical input from the mouse or keyboard will not affect the input queue's synchronous key state (reported by GetKeyState and GetKeyboardState), nor will it affect the asynchronous key state (reported by GetAsyncKeyState). However, the thread that is blocking input can affect both of these key states by calling SendInput. No other thread can do this." - quote from MSDN documentation

How could I block input events for all applications and operating system similar to BlockInput(), and still be able to read the mouse/keyboard events in my program? I am pretty sure this is possible because ShareMouse is doing it somehow.

Thanks in advance. I hope I was pretty clear in my request, if not I will try to elaborate more.
