Is there a tool to calculate line checksum of motorola S3 Record ?

For example, following is line of motorola S3 Record:

S325A000002000000000000000000000000000000000000000000000000000000000000000001A

To calculate checksum manually, one byte of size, four bytes of address, and all data bytes are summed.  Extract least significant byte
from the sum, take it's one's complement and that's the checksum.

Is there a checksum calculator or tool that will calculate the checksum ?

I use : to create  a new HWND

But requires the strike code for the window HWND chance his size

ex:  
bool HWND (chance size)
{
x = windowX
y= windowY

}

BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
   HWND hWnd;

   hInst = hInstance; // Store instance handle in our global variable

   hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,
      CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);

   if (!hWnd)
   {
      return FALSE;
   }

   ShowWindow(hWnd, nCmdShow);
   UpdateWindow(hWnd);

   return TRUE;
}

Hello,

after solving some ugly other problems with make, I run now into the problem about the CXXFLAGS. It looks like make do not use this FLAGS.  My makefile looks like:

CXX = g++
CXXFLAGS = -g -std=c++11 -Wall -pedantic
LDFLAGS=-g

root := /usr/share/doc/xsd/examples

include $(root)/build/cxx/rules.make
include $(root)/build/xsd/tree-rules.make




$(CXX) $(CXXFLAGS) -c 05_bxf2.cxx

XSDValidator.o:
	$(CXX) $(CXXFLAGS) -c XSDValidator.cpp

XSDValidator:
	$(CXX) $(LDFLAGS) -o XSDValidator.o 05_bxf2.o

clean:
	rm -f *.o

The repsone I got in termional after calling make

g++ -W -Wall -O3 -c 05_bxf2.cxx

Select all Open in new window

This is not what I added to the makefile. Any idea why make do not use the Flags?

I have really problems to understand makefile and its rules.
I created a makefile that works perfect. Now I want to remove objects before compile but it do not work with rm -f *.o
I get always the message "Missing seperator. stop"

# Build
# /opt/rh/devtoolset-4/root/user/bin/
clean:
    rm -f *.o

root := /usr/share/doc/xsd/examples

include $(root)/build/cxx/rules.make
include $(root)/build/xsd/tree-rules.make

XSDValidator: XSDValidator.o 05_bxf2.o
05_bxf2.o: 05_bxf2.cxx 05_bxf2.hxx
XSDValidator.o: XSDValidator.cpp 05_bxf2.hxx

Any Idea what I do wrong? Without "clean: rm-f *.o" it works well. I also tried to use a tab before "rm"
But nothing helps. It looks like "rm" do not work in makefile?

Hi, i wish if everyone is having a good day.
However i have an problem in mysql i would like to get the count of ids column in my table and plus 1 to the number how ever when i do like that it types +1 as string for example the result of counting was 3 it will add 3 to 1 like this 31 not 3+1=4 so i don't know how to solve this here's my code :

		String^ constring = L"datasource=...;port=...;username=...;password=..."; // Giving informations to the server
		MySqlConnection^ conDataBase = gcnew MySqlConnection(constring);
		MySqlCommand ^GetCount = gcnew MySqlCommand("Select Count(ID) from newdatabase.my_table;", conDataBase);
		MySqlDataReader^ myReader;
		MySqlCommand ^cmdDataBase;

		try {
			conDataBase->Open();
			myReader = GetCount->ExecuteReader();
			while (myReader->Read()) {
				int Got = myReader->GetInt32(0);
				cmdDataBase = gcnew MySqlCommand("Insert into newdatabase.my_table (ID) Values ('" + Got+1 + "');", conDataBase);//queries
			}
			myReader->Close();
			myReader = cmdDataBase->ExecuteReader();
		}
		catch (Exception ^Ex) {
			MessageBox::Show(Ex->Message);
		}
	}

Hello everyone.

I've seen that what I'm trying to do which is monitoring the file IO require the use of Window File System Filter driver and I've also looked into it but was a bit hard to understands especially as I'm not a C++ developer. What I want to achieve is to be able to trap file copy, creation, as well as file sources and destinations, lets say I'm copying a file within my computer I want to get the source path of the file as well as destination path of the file and also the file name as well and if possible with the application that is sending the file.

I saw that this can also inform you if there is file access(opening of file, reading of file) this is very much important to me to also get it if possible while the request of file open is created. I wan to trap this and if the file is one of my file then I want to first work on the requested file first (decrypt).

Thank you.

We just moved from WinINET to WinHTTP. The latter does not have an equivalent InternetCanonicalizeUrl function.

The WinHTTP docs say that WinHTTPOpenRequest does this automatically but there is nothing there that specifically addresses this.

According to this reference you can use WinHTTPCreateURL which uses a URL_COMPONENTS structure to define the various URL parts. In the latter the lpszExtraInfo property is where you put the ?param=xyz& ... part.

Here is my problem - one of the parameters in the paramter string needs to be canonicalized as it could contain non-URL friendly characters (Example &).

With the WinINET version we used InternetCanonicalizeUrl on the specific URL parts which were then appended to the URL string.

Example
If we have a URL now that looks like this

mydomain.com?param='Name & Surname','Description'

Select all Open in new window

And we pass that to WinHTTPOpenRequest - it does not know that the & in Name & Surname is data and not a parameter separator.

Question:
How do we canonicalize individual parameters in the URL with WinHTTP

language : c++
(tools : visual studio , acrobat reader)
thanks a lot

MFC CComboBox won't display wide characters.
I'm using VS 2008, UNICODE is defined in the build and all of the prompts and other strings in the app are coming out fine.
The first try I just added the strings like any combobox and the display and dropdown showed a black line for each
character like the font was wrong.

I tried to SetFont to no avail.

I went to an owner-drawn combo box with no change.
The string shows correctly in the debugger (both in the watch and in the hover box).
the string is "Активна" and, copied from the debugger window,  shows up fine in WordPad.

In DrawItem I did:

      CString fontName;
      CDC dc;
      dc.Attach(lpDrawItemStruct->hDC);
      dc.GetTextFace(fontName);

//fontName is "MS Sans Serif" which is is expected and what I am using in the rest of my app and is reported to support Cyrillic.
//The rest is :

      CString thisString;
      GetLBText(lpDrawItemStruct->itemID, thisString);      

//note that at this point,  thisString shows to have the correct string in the debugger

      dc.TextOut(rc.left+iOffsetX, rc.top + iPosY,thisString);      

And I get " ||||||| "  in the combo box (both edit box and dropdown).

      dc.TextOut(rc.left+iOffsetX, rc.top + iPosY,L"TESTSTRING");
works fine.

Any ideas would be helpful...I've been working this way too long.

I had this question after viewing C++ COM Method with Optional Arguments.

I am trying to produce a COM object in Visual C++, where one of the methods accepts optional arguments. Below are the interface declaration, the class implementing the interface, and the implementation of the method taking an optional argument. As it stands, it compiles. But when I try to call the function from an ASP page using VBS with the supposedly optional parameter missing, I get the following error


Microsoft VBScript runtime error '800a01c2'
Wrong number of arguments or invalid property assignment: comObject.ShowFinalSql

Following code in IDL
interface IWPharma : IDispatch{
   [id(2), helpstring("method ShowFinalSql")] HRESULT ShowFinalSql([in] BSTR query, [in] BSTR cleanup);

in C++:
    STDMETHOD(ShowFinalSql)(BSTR query, BSTR cleanup) override

in VB with error:
