Native code step through goes out of sync

originSH24-Jul-07 1:08

When in a native c++ class, in a /clr project, stepping through is getting out of sync of where it should be.

i.e.

1 if(fileSpec.GetLength()==0)
2 {
3 printf("You must specify a filename!\n");
4 return 1;
5 }

I put a breakpoint on line 1. Then F11 to step into. The if statement returns false and so it should step to 5 or beyond. Instead it stops on 4.

Any ideas why?

ms office automation from NT service in 64 bit OS

Hi,

When I am trying to automate MS Word (32 bit) from a NT Service (32 bit). The word runs as a 64 bit application (as evident from the task manager).
But if the same code is run as a thread from a Windows application word runs as 32 bit.
How can I automate word to run as 32 bit from the NT sevice??

Thanks,
Indra

You;re trying to automate Word using C++ and .NET ?

No, using C++ and COM.
Code I am using:

VARIANT root[64] = {0}; // Generic IDispatchs
VARIANT parm[64] = {0}; // Generic Parameters
VARIANT rVal = {0}; // Temporary result holder
int level=0; // Current index into root[]

// Initialize the OLE Library...
OleInitialize(NULL);

// Line 1: Set oWord = CreateObject Word.Application
CLSID clsid;
CLSIDFromProgID(L"Word.Application", &clsid);
HRESULT hr = CoCreateInstance(clsid, NULL, CLSCTX_LOCAL_SERVER|CLSCTX_INPROC_SERVER, IID_IDispatch, (void **)&rVal.pdispVal);

rVal.vt = VT_DISPATCH;

VARIANT oWord = {0};
VariantCopy(&oWord, &rVal);
VariantClear(&rVal);

// Line 2: oWord . Visible = 1
rVal.vt = VT_I4;
rVal.lVal = 0;
VariantCopy(&root[++level], &oWord);
hr = AutoWrap(DISPATCH_PROPERTYPUT, NULL, root[level].pdispVal, L"Visible", 1, rVal);
VariantClear(&root[level--]);
VariantClear(&rVal);

// Line 3: oWord . Documents . Open C:\\Test.doc
VariantCopy(&root[++level], &oWord);
hr = AutoWrap(DISPATCH_PROPERTYGET|DISPATCH_METHOD, &root[level+1], root[level++].pdispVal, L"Documents", 0);

The purpose of the AutoWrap function in this sample is to wrap the calls for GetIDsOfNames and Invoke to facilitate automation with straight C++.

OK, then you're in the wrong forum. Try the Visual C++ forum.

Hi,

I have a C++ (Borland 5.02 - I know is old stuff...anyway) I have function where I can print reports. Now what I need to to modify this function to instead of printing to a printer I need to save that as MDI or PDF file, but I want to bypass the Save As dialog box because I have several hundreds of reports to print. How can I do that? Confused | :confused:

Please help!!!

Borland does not support .NET, therefore you're in the wrong forum. Even in hte right forum, I'm not sure how many people can offer Borland specific help.

difference between these directives

For managed C++ what is the difference between:

using
#using
using namespace

?

Thanks in advance

A quick look with the F1 key yields:

"The #using Directive...Imports metadata into a program compiled with /clr."

"The using directive allows the names in a namespace to be used without the namespace-name as
an explicit qualifier."

Mixed C++ won't invoke JIT

Hey All,

I've run into a problem where under Visual Studio 2005 if a crash occurs in my managed code, I simply get the MS .NET Framework dialog box. Of course it tells me to make sure the reg key is set, debugging info is turned on and that my config file sets <system.windows.forms jitdebugging="true">. I seem to be doing everything, yet I can't get the debugger to open.

Any ideas? Am I missing some other step, or does mixed code fail to invoke the debugger?

Thanks!

Need for Virtual Function?

Hi,

I have some doubts in Virtual functions.

What is the use of Virtual Functions?

In which scenario, virtual functions will be useful ?

For what real time problems, virtual function is preferred?

Please clear my doubt.

Thanks,
Arun AC

It's all about polymorphism!

A Googly search on "C++ virtual functions" yields billions of articles on the subject (ok, maybe
not that many).

For example: Polymorphic and Virtual Functions in C++[^]

Hello Sir
I am very happy because for the first time I print in Visual c++ NET with report. This what I do:
SqlConnection^ cprl = gcnew SqlConnection();
cprl->ConnectionString = "Persist Security Info=False;Integrated Security=SSPI;database=payroll05;server=sem;Trusted_Connection=Yes;" ;
cprl->Open();
Ds_report^ data = gcnew Ds_report();
SqlDataAdapter^ adapt = gcnew SqlDataAdapter();
SqlCommand^ Cmd = gcnew SqlCommand();
Cmd->CommandText = "select* from ficag21";
Cmd->CommandType = CommandType::Text;
Cmd->Connection = cprl;

adapt->SelectCommand::set(Cmd) ;
adapt->Fill(data,"ficag21");

rptsearchsig->SetDataSource(data);
rptsearchsig->Load("C:\\Documents and Settings\\miki\\Mes documents\\Visual Studio 2005\\Projects\\payroll\\payroll\\rp_signal.rpt");
rptsearchsig->PrintToPrinter(1,true,0,65500);

It's very simple but I take three days to do it.

I will send you my article to explain well for helping others that are in the same difficult.

Thanks to all halp me

Here's an example using WMI to get the MAC addresses for all the "Ethernet 802.3" adapters on
the system:

#using <System.Management.dll>
using namespace System::Management;
...
ManagementObjectSearcher searcher("SELECT Name,MACAddress FROM Win32_NetworkAdapter WHERE AdapterType = 'Ethernet 802.3'"); 
ManagementObjectCollection::ManagementObjectEnumerator^ enumerator = searcher.Get()->GetEnumerator();
while (enumerator->MoveNext())
{
   Console::WriteLine(enumerator->Current["Name"]);
   Console::WriteLine("   {0}", enumerator->Current["MACAddress"]);
}

Which language are you coding in? This forum is for dot net cpp stuff. Whatever the case you'll probably need to provide some more info or post some small sections of your code. I've been doing some UDP stuff the last few months so I might be able to help
