Send the control a LVM_SETITEM message.

for a simple list box there is lvnselchange message.

Actually, that's the notification message (LVN_ITEMCHANGED) that a list control control sends its parent when an item has changed. Perhaps you are thinking of the LB_SETCURSEL message.

From .exe to .lib

Hello all,

I have a working BIG MFC project X. Now I want to create a new project Y(or another interface) that will use the older MFC project X as a library from which classes and methods are called. I changed the general properties of the X from .exe to .lib and Linked Y to X in the linker properties.

The problem is that I lost all linker options that were in X (I used to link X to other libraries). Whatis the solution for this?

Thank you very much.

Regards

Create a temporary DLL project and make a note of what linker options are used. Incorporate those into X.

Do you mean that I should creat a DLL project that link to these libraries and then put this DLL in X, thus X is linked to the libraries?

How to create this DLL project and how to link it to X?

Notice the word "temporary" in my suggestion?

Use MFC's AppWizard.

I can't get you. This is complicated for me. I am a beginner. Can you explain in more details and easier steps?

It doesn't get any easier than what I've already provided. Since you have already created a "BIG MFC project," we must assume that you are at least somewhat familiar with the process. In any case, see here.

Dont take the "BIG" word to that extent. It is big in core not in interface. I'll check the links and go back to u soon.

Thanks anyway.

How can I convert from string to LPCSTR?

David Crow11-Jul-06 2:20

Re: string to LPCSTR [modified]

What's wrong with:

string str = "Hello";<br />
LPCSTR lpStr = str.c_str();

string ? or CString ?

if std::string :

std::string str = "yop";
char psz[255] = NULL;
::strcpy(psz, str.c_str());

if CString :

CString str = "yop";
char psz[255] = NULL;
::strcpy(psz, (LPCSTR)str);

This is syntactically incorrect. You cannot convert from const char to char[255]. You'd need to use strcpy(), or equivalent, instead.

How to set a temporary truststore for WinHttp ?

csTemp.operator LPCTSTR()

Ajeesh,

why do you think we define operators overloads, if you call them like any other functions ?!

dont use csTemp.operator LPCTSTR(), use instead (LPCTSTR)csTemp.

Hi all,

we use WinHttp with SSL enabled for secure client/server connections. We have a private PKI and need to import our CA certificate into an appropriate truststore, so the SSL handshake runs through. Preparing a truststore outside the application is no option. We started with temporarily importing the CA certificate into the system certstore, but of course this fails for users without admin rights. We didn't like this approach, because it side effects all other applications accessing the system truststore, but saw no other choice to achieve our goal.

My questions are:
- can we create a temporary truststore and tell WinHttp to use this truststore for the SSL handshake?
- if not, what other choice do we have?

Thanks for your help,
Emil
