Visual C++ :: Place Binary Array Into And Then Retrieve From Registry
Feb 12, 2013
I have used the following code to attempt to place a binary array into and then retrieve from the Registry. I am a member of the local Administrator group. I have verified that the Registry for the app has a binary array 32 bytes in length under the key "settings" / "keyb" ab 12 cd ...
Code:
// in header
unsigned char m_key[32];
int m_nKeySize;
// in implementation
// int ctor
AfxGetApp()->GetProfileBinary(_T("settings"), _T("keyb"), (LPBYTE*)&m_key, (UINT*)&m_nKeySize);
// in OnDestroy
AfxGetApp()->WriteProfileBinary(_T("settings"), _T("keyb"), (LPBYTE)&m_key, m_nKeySize );
Here is a copy of the binary array in the Registry:
7D DE 2B 30 E7 06 12 AC 99 60 8C 26 21 FC 8E 5B 66 DB 72 9E A2 00 BE 15 E1 8B 67 31 E5 EC 8B 15
Here is the binary key retrieved from the Registry using the code above:
D0 EB 26 00 CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC CC
I'm trying to set up some basic communication between two programs via the registry.
For this I would like to use the functions
Code: int value=10; CString strSection="Data"; CWinApp* pApp = AfxGetApp(); pApp->WriteProfileInt(strSection,ValueName,value); and
Code: CString strSection="Data"; CWinApp* pApp = AfxGetApp(); int value=pApp->GetProfileInt(strSection,ValueName,0); which read/write to the application's registry.
Is there some way of making two different programs use the same application registry?
In a typical MFC application I use SetRegistryKey(_T("My_Company")); to set the root registry entry for my application. The MFC application however creates an entry by the name of executable where it stores all the settings of that application. I don't want that because we often change the name of executable and I want it read registry from the same set location. As example if my application name is Calculator.exe and Calculator_debug.exe it creates two different registry settings.
I have a 32-bit application that I've been maintaining for about 12 years and it runs on every Windows platform up to Windows 7. In all that time I've been using CWinApp::GetProfileXxxx() and CWinApp::WriteProfileXxxx() calls to read and write my program settings (about 70 settings) in the Registry. The settings are read from the Registry at start-up and written to the Registry when the program closes. There is also a method for the user to read and write the program settings to an INI file using the same code as the Registry access.
On my Windows 7 system the Registry read/write works just like it always has on all previous Windows versions. However, on some customer's Windows 7 machines there appears to be a problem with the Registry access. The program settings are either not being read from the Registry or are not being written to the Registry. I think the settings are not being written - but I don't know that. When the user uses the INI file the settings appear to be read and written.
The customer has complained a bit (I'd complain too) but doesn't have the time or doesn't want to take the time to run some simple tests for me to find out what's going on with his Windows 7 system.
So here is my question: Are there any user account settings or permissions that can block the program's access to the Registry? He claims he is an Administrator but I can't even get him to verify that.
When I write to the Windows 7 Registry at HKEY_LOCAL_MACHINE, I get a return code of 5 which is the "access denied" message when I execute RegCreateKeyEx.
This happens even if the User has administrator rights.
How can I tell Windows 7 to allow the program to write to the registry?
The application is a 32-bit application and it should be allowed to run in either a Windows 7 32-bit or 64-bit machine.
I noticed that when I run certain popular programs, a User Account Control dialog box comes asking:
"Do if you want to allow the following program from an unknown publisher to make changes to this computer".
Should my application call User Account Control and if so, how do I do it in C++ Visual Studio 2008?
I also found out that 64-bit Windows machines have two registry hives. Is there a different code to handle the same task?
How can I create in my C++ program so a user can paste a text and then choose a character on specific line and place?. The above thing isn't that important. I just want to place a character on a specific line and place.
I mean something like this:
Enter a character:
You choosed " / "
On which line do want the character?
You choosed "Line 1 and 2"
Where do you want the the to appear on the line? (left or right)
I used to retrieve IP and NIC information by querying windows registry. Now I'm trying to use GetAdapterAddresses() API. Using GetAdapterAddresses() to get IP is not that easy, I need to dig a long deep as I check some examples so far, anyways my question is: Calling this API will return success on all versions of Windows ie: 32bits & 64bits ?
Though Microsoft has not opened any source, where this API is actually retrieving Windows IP information.?. Is it reading Registry or some windows file.
Assume you want to read from a file and place the data from the file into an array. The array can hold 10 integers. The file may contain any number of integers with 1 integer per line. Fill in the missing loop test condition so that we will read from the file until either end of file occurs or the array is full. Note we are using cin to read from the file since input redirection is being used.
When I use SHBrowseForFolder I can retrieve a PIDL of the selected folder and with this PIDL I can get the path with SHGetPathFromIDList.
Now, given a path to a folder, I want to retrieve its PIDL. How can I do it? I tried SHParseDisplayName() but seems that function is unsupported in VC++ 6.0
I am having problems figuring out how to place a list of strings from a text file into a multidimensional array that is something like words[NUM_WORDS][MAX_LEN]. I already run through the file once and count the number of words in it. I have tried a number of loops using fscanf and fgets, but I'm not sure if I am using them right -- this is my first time using them. The text file is a list of words in a dictionary, so the wordCount is about 45340.
Here is my code:
#include <stdio.h> #include <string.h> #define MAX_LEN 46 int main(){ int wordCount = 0; FILE *inputFile, *outputFile;
[Code] ....
Like I said, the wordCount portion works. I added the printf statements at the end to see if anything was being saved, but it just prints two new blank lines. New to file reading and writing.
And then the Calculator is shown in domainuser1 desktop, but the process is running in domainuser2 account.
When running Spy++ (either wither domainuser1 or domainuser2) to view the calculator window, the Windoe Proc field is shown 'Unavailable' I also try to call GetWindowLong against this window, it will always returns NULL.
I am just wondering if it is possible to retrieve the Window Proc of the window running in a process of another account, is is possible?
I am trying to read a tab delimited file containing 8 columns and store each element of the column as an 1-dimensional array. Though the program prints the strings correctly as in the commented printf but it doesn't give me first_col[0] value and so on. My code is as follows:
Code:
#include<stdio.h> #include<stdlib.h> #include<string.h> int main() { FILE *int_file1; int BUF = 1024;
[Code]...
The inputfile test.txt has the following elements:
I am developing an application which monitors file changes and also registry key changes during a driver installation. I have used this code from internet, but doesn't works.
public void WmiChangeEventTester() { try { WqlEventQuery query = new WqlEventQuery( "SELECT * FROM RegistryValueChangeEvent WHERE " + "Hive = 'HKEY_LOCAL_MACHINE'" + @"AND KeyPath = 'SOFTWARESchneider ElectricDMODBUS' AND ValueName='CurrentVersion'");
I know how to add a new item to a folder right-click menu, using the registry, but it won't show up on file right-click menu. give me a link to how this is done? I want this new menu appear on every file R-C menu, file registered with the system or not. Is there a simple way to do this as adding a item to folder R-C menu, or will i have to iterate all the registered file types in registry to do it. I tried google with many search terms, but i can't find a source for this.
I am working on a physics engine, following the cyclone physics engine source code but a I am having trouble with an error that is occurring in my overloaded operator== function. It is saying that the information is unaccessible.
I'm trying figure out how Windows Firewall functions by experimenting with Bittorrent's add exception to windows firewall option, I deleted the entry from the Firewall options and also located that the regkeys are in HKLM/System/CurrentControlSet/Services/SharedAccess/Parameters/FirewwallPolicy but I can't figure out what registries are made when an application is added as an exception in the Windows Registry.
The first time my application opens up, it should get the local date out of the System and store this in a registry key. But the second time it should get the date stored in that registryKey and compare it to the date right now.And there is where I am stuck, I just don't know how to get the date out of that key and compare it to the date right now.
This is my code:
RegistryKey key1; private void btnTrial_Click(object sender, EventArgs e) { DateTime current = DateTime.Now; key1 = Registry.CurrentUser.OpenSubKey("myKey"); if (key1 == null)
[code]....
at the last "if" statement it should compare the date stored in the key with the DateTime.Now.
I was browsing the web looking for simple yet fun programming challenges and crossed this one. I figured out how to reverse the string in place but I want it to read "blue is house the". I approached it in two ways for the heck of it. My idea was the second one, the first one I googled. I didn't know a simple rbegin() could do that, pretty neat.
I found the question here.[URL] ....
Code: #include <iostream> #include <string> int main(int argc, const char * argv[]) { std::string phrase = "The house is blue.";
I need function to determine where to place new element in sorted array. I want to use binary search to find index where element should be placed, when push all others.
Prototype should be something like
int WhereToPlaceElement(ElementType hash); // uses private atribute ElType** elements
I have tried my best to write, but all tries ended in inf loops and reading invalid locations of array.
