Hello,
After upgrading the compiler to v141, i am unable to use the COM c++ attribute `export`.
The compiler throws error saying - error C2337: 'export': attribute not found. Does this version of compiler not support this attribute at all ?
Thank-you for your time!
Hi, I want to ask when using MFC, is there any 3rd party controller that supports it? eg syncfusion, telerik, ..
because I want to use more features and more modern for my project.
Currently I am only allowed to use MFC and WPF, but I do not know anything about wpf and how to link it to c ++.
Many thanks!
Hello,
We Have updated to Visual Studio 2019 from 2017, but we kept MSVC 141.
With Visual Studio 2017 we could step in our C++ code using mixed debugging from our managed code.
In Visual Studio 2019 this does not work any longer.
the list of loaded modules does not even show the dlls we want to debug.
Is it possible that we have to update to MSVC 142 so that mixed debugging will work in VS 2019?
Thx,
Hinrich
Hi All,
The following error message is occurring again and again while rebuilding my VS-2019 solution since last Wednesday day. I have done all my possible troubleshoot at my end. However, issue still persist. Could you please help me on this?
1. Giving full access to solution folder
2. Remove read-only access to the folder
3. Disable security essentials/firewall
4.Provide full access to the hard disk driver
ErrorCS0009Metadata file 'E:\.............................ces.dll' could not be opened -- Access to the path 'E:\............................................ces.dll' is denied.
Thank you!
hello, i want to ask if i do this right?
I think when declaring static in .h file
Then in .cpp I declare include .h, it will work as in one file.
however it does not seem to work! where i was wrong?
when i debug: The variable is not initialized
however in another similar project, it works. It seems to be possible due to the compiler structure (is this possible?)
In C#, we can assign multiple methods to the delegate using '+' operator.
In C++, is it possible to assign multiple functions to the function pointer?
If so, how to do it?
I am trying to send keyboard inputs, similar to what sendkeys does in C++
From https://docs.microsoft.com/en-us/windows/uwp/design/input/input-injection, I can see C# code like this:
_inputInjector = InputInjector.TryCreate();
How can I do this in straight C++ instead of C#?
I added the following code to my program.
string str;
str="00."+'0';
The '0' part was converted to a decimal number then added to str giving 00.48
I would have expected to get str="00.0".
In C# I do get 00.0.
Yes I know I could use "00."+"0" but the compiler should have added strings or thrown up an error.

here is my c++code:

{

{
ips.push_back(ex);
ex = "";
}
else
{

Hi,

And also i have tried :

I think I need to set up named pipe for moving a stream of bytes across a solution to a different file. I just read this warning:
Windows 10, version 1709: Pipes are only supported within an app-container; ie, from one UWP process to another UWP process that's part of the same app. Also, named pipes must use the syntax "\\.\pipe\LOCAL\" for the pipe name.
My OS is Windows 10 Pro, Version 10.0.18362 Build 18362
Will I have any problems? And what's UWP? Universal Windows Platform? How will I find out if I have one or need one?
Thanks, - MyCatAlex
Hi, I want to ask this problem: my code have a pointer scnf to function
<Do not edit the total sum function>
I want when the totalsum executes will call scnf with first parameter equal to pt1 (pt1 is entered by the user - it may change)
I tried to use
scnf = newSum; scnf (pt1,5);
However this doesn't work? I think it is possible to use global variables, but is there a different solution?
int pt1=3
int (*scnf)(int pt, int mt);
scnf=newSum;
scnf(pt1,5);
rc = Totalsum( ssname,
L"Select number",
0,
scnf,
return_sum);
//---------------------------------------------
int newSum(int num1, int num2) {
custom(num2); //custom function
custom(num1)
return 1; //
}Many thanks!
If you look at the page with the description of the SECURITY_DESCRIPTOR structure you can see that a function to define "Revision" is missing, or am I missing something? If it is really missing, then how people use this structure? I really need it.
What is Cbz1? Another puzzle?
Thank you, - MyCatAlex
Hi,
I'm getting a ton of C4986 warnings. The code in question uses the STDMETHOD macro in the header file and the STDMETHODIMP in the implementation file. I had a look at the definitions and as it turned out, STDMETHOD is defined with __declspec(nothrow) whereas STDMETHODIMP is not.
What is the reason for that? Is there an elegant way to get rid of the warnings in this particular case?
VS 16.4.5, SDK 10.0.18362.0

when I run my code it gives a error message at line 32 saying missing file specification after redirection operator.
I have added what i thought were missing Sile specification and got no where with it and i have looked into how to get rid of the problem and have got nowhere
the code that makes the error occur is / cout << ip << endl; how do I remove the error without removing the code?
Hello,
I don't have any experience in C++ and I need to create a console application to create one Outlook profile with two message service for Exchange
Why C++? Since Outlook 2016 PRF files are no more supported and Extended MAPI needs to be used
Found the following code on Microsoft Website
I changed the code to include tow emails instead of one but having an issue with CreateMsgService
Basically the second message service is created but empty
Copied the code at the end of this message
Thank you for your help

// CreateProfile.cpp : Defines the entry point for the console application.
