I'm writing a dialog by MFC.
I need to send data out through RS-232, using Modbus protocol.
I know there are many classed written for serial communication, but not for Modbus.
Does anyone have already fought with modbus and survied?
Please give me sone advice.
Thanks.

I am writting an openGL wrapper which will take screen shots of different games, it works good on most of the games.
but there is a problem in MOHAA, Medal of Honour Allied Assult.
I am getting the VIEW PORT with below code, it works ok when the game is in the main screen but its not getting the entire screen when the game intro movie or the game is running. This code takes a specific rectengle in the entire screen this means that currently the game VIEW PORT is set there.
int width=800; //default image width
int height=600; //default image heigh
GLint viewport[4];
glGetIntegerv(GL_VIEWPORT, viewport);
if (viewport[2]>0 && viewport[3]>0)
{
width= viewport[2];
height= viewport[3];
}
I will really appreciate if someone can help me get the current screen when the VIEW PORT is not the entire screen

I have created a Database application that uses ODBC. So far i have been able to search only if i get an exact match by using m_strFilter. I would like to be able to filter partial matches as well.
Question: How can I search my records and filter partial matches as well as exact matches?
App info: MFC SDI with database support
Code:
<br />
void CDrinkRecipesView::OnSearchbutton2() <br />
{<br />
CString m_Input="";<br />
GetDlgItemText(IDC_SEARCHEDIT, m_Input);<br />
<br />
<br />
m_pSet->m_strFilter = "RecipeName = ?";<br />
m_pSet->m_RecipeNameParam = m_Input;<br />
m_pSet->Requery();<br />
<br />
if (m_pSet->IsBOF())<br />
{ <br />
m_pSet->m_strFilter = "RecipeName = RecipeName";<br />
m_pSet->Requery();<br />
<br />
AfxMessageBox("Record not found!");<br />
UpdateData(FALSE);<br />
m_ctlSearchEdit.SetFocus();<br />
m_ctlSearchEdit.SetSel(0,-1);<br />
}<br />
<br />
else<br />
{<br />
UpdateData(FALSE);<br />
m_ctlSearchEdit.SetSel(0,-1);<br />
m_ctlSearchEdit.Clear();<br />
m_ctlSearchEdit.SetFocus();<br />
}<br />
<br />
}<br />
thanks

Anyone know how to hook into the add/remove programs applet and determine if it shows an application is installed. If it is...uninstall it??
Thanks!!

Enumerate HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall, and for every sub-key where the SystemComponent value is missing or zero, those are the installed programs. The UninstallString value gives the command to run to uninstall the program.

That gets it! Thanks!

I don't know how to "hook" into it, but to run the applet, type:
control appwiz.cpl

How do I tell it to open up a dialog window when a buttom is clicked on?
and how do I tell it to close a dialog window when a button is clicked?
how do I tell it to exit the program when a button is clicked?

To display an instance of a new modal dialog (eg: CNewDialog) when a button is clicked, create the dialog on the stack and call its DoModal() method.
CNewDialog dlgNew (this);
int nStatus = dlgNew.DoModal();
...
To close a dialog from within itself, call the base class method OnOK() or OnCancel(), depending on whether you want to indicate that the user ended the dialog by pressing OK or Cancel.

for dialog open use domadal
for close dialog send the message Wm_close
for exit program called exit

I know nothing about C++ so you people need to explain what you are talking about
|
|
|
|
|
you have to ask clearly what exactly you wanted to do.so that we can help you in that direction.
