Yes. This is a dialog based application. IDC_EDITCustLog is an edit box placed inside the dialog.

Hi KK_VP (Whats this yar)??????!!!
One more catch up from my mind..
You told your callback function is called from a dll..
From the callback function you are tring to set the window text.
The problem could be, you might have different thread(Secondary thread..), from where your callback function could be called. To check this, display a message box or trace the currentthreadid() value in your InitInstance() and also in your notification function. If you get different values, you must do the PostThreadMessage to the thread where you have created your dialogs..
Hope the above approach will help you..

Hi,
its wonderful to get HTML out of MIME buffer. I am able to get HTML out of almost all of my MIME buffer but it is failing for some cases.
Here is the MIME buffer where it crashing when I try to use get body from it.I anaysed that it always crash if HTML body starts with <DIV> or <P> tag.
Content-Transfer-Encoding: binary
Content-Type: text/html; charset=ISO-8859-1
<div><STRONG><FONT color=#ff9900>RTF NOT NULL Without attachment Title-099</FONT></STRONG></div>
code:
// hTempFile it contains handle of My MIME buffer file
CFileSystemStream SourceStream(hTempFile);
IMimeDecoderPtr Decoder;
IPersistStreamPtr pPersist;
Decoder->QueryInterface(&pPersist);
pPersist->Load(&SourceStream);
IMimeBodyPtr Body;
Body = Decoder->Body; -----------------------------------> it crashes here even I tried to put try catch block it never catch.
Mentioned MIME buffer comes from Quick Place. Quick Place is able to convert these MIME buffer into HTML correctly.
Is there any validation check for MIME buffer for MIMEsniffer.dll? How to validate the MIME buffer. I tried to put <HTML> </HTML> and <BODY> </BODY> tag to my MIME buffer and passed it to MIMEsniffer.DLL even it gets crashed.
could you help me out ?
Thanks in advance.

Just like that? Shouldn't you be creating an object to instantiate that interface?

Hi!
How can I create a button on a Dialog that can be dragged and dropped?
Thanks!
|
|
|
|
|

Hi,
There is no direct method available for this..
You can follow the following steps.
Assumption: Parent window and children to be draged already created
You need to handle three mouse events.. WM_LBUTTONDOWN, WM_MOUSEMOVE, WM_LBUTTONUP
1. In the WM_LBUTTONDOWN message, call the SetCapture function with the control ID
2. In the WM_MOUSEMOVE message, call the GetCapture method and check the returned Window handle againt the your window child control window handle. If both are same, call SetWindowPos() to set the control new position.
3. In the WM_LBUTTONUP, check for the GetCapture() returned window handle is equal to your window control handle. If it is call ReleaseCapture() method, and once again place the window control by using SetWindowPos().
One more thing you have to take care is , when user clicks the button, he can drag that button out of parent window. To avoid such a situation, call the ClipCursor() function with the parent window rectangle size values...Then don't forgot to free the cursor. That you can do it by ClipCursor(NULL)..
Enjoy programming...

Thanks!
But can this be done using OLE drag and drop?
If so, how do I do it?
Can't seem to find any good information of how to drag Controls.
Thanks!

No. You cannot..

Hi Guys,
I hope someone here knows more about managed c++ than i do. 
The problem: I get a char* from a structure, and i need to convert it to a String*(or a Stringbuilder). The way i do it is hopelessly inefficient. Is there any way to improve on this.
<br />
Mail *mail = new Mail();<br />
<br />
for (int a=0;a < 1000;a++)<br />
{<br />
mail->String = new String(struct[a].subject,0,struct[a].subjectSize); <br />
}<br />
What i'd like to do is some thing like this. But i dont know how.
<br />
Mail *mail = new Mail();<br />
mail->String = new String( <br />
for (int a=0;a < 1000;a++)<br />
{<br />
mail->String =
}<br />
Thanks

Hello,
I don't know what you are trying to do here, but you initialize the mail object a 1000 times and in the end it will only hold the last element.
Let me get the case clear here: you have an array of 1000 structures and one mail object. You want 1000 email objects initialzed with each of the structures. Right?
So please describe your problem a little better, because now it doesn't make much sense to me.

Hi Bob,
Thanks for the reply. I'm creating only one instance of the Mail object. In each iteration I instantiate a new String from the char*
I got from mailStruct[a].subject, and I raise an event (The mail object is processed on the other side).
<br />
Mail *mail = new Mail();<br />
<br />
for (int a=0;a < 1000;a++)<br />
{<br />
mail->String = new String(mailStruct[a].subject,0,strlen(mailStruct[a].subject)); <br />
MailEvent(mail);<br />
}<br />
A new String* instance is created with each iteration. This translates into a new memory allocation on each iteration and more work for the garbage collector.
So i'd like to change the code so that i create only one new String.
<br />
Mail *mail = new Mail();<br />
mail->String = new String (
for (int a=0;a < 1000;a++)<br />
{<br />
mail->String =
MailEvent(mail);<br />
}<br />

ok, I think I get it, you more or less want to send a 1000 email with different strings ?
I think your on the right track with your second example.
is the Main object you own ? does it allocate the String object when it gets constructed ?
I would change the definition of the String member to not be dynamically allocated; if not, you will need to allocate it like you do before the loop.
if the String is a build-in type of the managed c++ language, just assign it a new string in the loop should remove the old one and put the new one in;
Be certain that if you allocate it with new, that youp delete it ( or not, it might be collected later ).

You're spot on. Thats exactly what i'm doing.
I defined the Mail as a managed struct and it contains a bunch of managed c++ Strings.
The Mail struct doesn't allocate the String when it's constructed. (This is exactly what it looks like)
typedef __gc struct Mail
{
String *entryid;
String *tempid;
String *storeid;
String *subject;
String *fromName;
String *fromEmail;
}
The String is "newed" with every iteration. You're right, the garbage collector should take care of this. But why put the garbage collector under strain, when it may be unnecessary.
How can i allocate the memory for the String only once? But change its value a 1000 times?

Since string is a class, it must have member functions. So, you should be able to use those to alter it's contents. The most logical thing would be that operator = is implemented to replace the contents with something else.

Hello guys,
i'm stuck with this problem, i wrote a class wich handles the resizing en reposition of controls when a dialog resizes, but the problem is when I resize the dialog from the top or from the bottom you see a ghost of the control. This gives the effect that the controls are shaking during a resize.
The problem I think is, is that when MFC resize the dialog it updates the dialog and it's controls so you will see the controls with their previous x & y coordinates, then mfc calls my overriden onsize where i update the controls coordinates and size and repaint the dialog. So my question is how can i stop mfc from repainting the dialog when is resized so i can do this manual after mine onsize.
I checked other implementations of the CResizableDlg classes articles here, but they seem to have the same problem.
Anyone got some suggestions 
Thanks Remco

How are you handling the OnEraseBkgnd message?
I would recommend something like this:
BOOL CYourDialog::OnEraseBkgnd(CDC* pDC)
{
static int controlsNotToBeErased[] =
{
IDC_REFINE_BUTTON,
IDC_SCRIPT,
IDC_AUTOCLIP,
IDC_CLIP,
IDC_REFINE_CONFIG,
IDC_SCRIPT_SETUP,
IDC_SUPPRESS_CO2,
IDC_SUPRESS_WATER_CAPACITY,
IDC_SET_COMBO,
IDC_REFINE,
IDC_GRAPHS,
IDC_REFINEGRAPH,
IDC_CO2CHECK,
IDC_CO2,
IDC_SOLUBILITYCHECK,
IDC_SOLUBILITY,
IDC_VOLATILITYCHECK,
IDC_VOLATILITY,
IDC_GLPKA
};
CRect clip;
pDC->SaveDC();
for (int i = 0; i < sizeof(controlsNotToBeErased) / sizeof(int); i++)
{
CWnd *pWnd = GetDlgItem(controlsNotToBeErased[i]);
if (pWnd && pWnd->IsWindowVisible())
{
pWnd->GetWindowRect(&clip);
ScreenToClient(&clip);
pDC->ExcludeClipRect(&clip);
}
}
pDC->GetClipBox(&clip);
pDC->FillSolidRect(clip, GetSysColor(COLOR_BTNFACE));
pDC->RestoreDC(-1);
return FALSE;
}
This should hopefully reduce contro flicker etc.
If you vote me down, my score will only get lower

The problem is all of the painting that's going on as you move each control. Try looking at the DeferWindowPos[^] API function, which lets you change the position of several windows and then update the screen all at once.

 Hi all!
I created a file DLL by VC++.After that to insert in VisualBasic I do following:
From Menu choose Project->Reference...-> Browse to file *.DLL (Adsoft.DLL)
Choose in ComboList (Prọect/Library)->Adsoft
But any class and function in there don't to appear.
If possible. Can you give me an example ?
Thank !

Thanks DavidCrow!
I don't think your ? I write this class following:
// Adsoft.H
#ifdef ADSOFT_IMPL
#define CLASS_DECL_ADSOFT _declspec(dllexport)
#else
#define CLASS_DECL_ADSOFT _declspec(dllimport)
#endif
#undef AFX_DATA
#define AFX_DATA CLASS_DECL_ADSOFT
class AdsoftDLL : public CSocket
{
public:
BOOL CGetCheckErro(int nErroCode);
};
#undef AFX_DATA
#define AFX_DATA
// Adsoft.cpp
#include "afxdllx.h"
#include "Adsoft.h"
BOOL CGetCheckErro(int nErroCode)
{
if (nErroCode==0)
return FALSE;
return TRUE;
}
But to happen phenomenon don't to want

I'm really not sure what you've provided here. Is this code that does not work? Are you wanting to export the AdsoftDLL class or just the CGetCheckErro() method? After a successful compile/link, have you verified with either Dependency Walker or Dumpbin that the DLL has the correct export table?
Thangnc wrote:

In adsoft.cpp, shouldn't this be:
BOOL AdsoftDLL::CGetCheckErro(int nErroCode)
