changing the cursor postion in a editable combobox???
-
hi everyone, i have a problem, i'm using a editable combo box inmy project and also i have added an event to combobox that when a user keys in any data it will check for the data i the database,if the data is there the data will be listing in the combobox. My problem is after updating the combobox the cursor postion will be at the start(like "|100").I need the cursor should be postioned in the last of line. please reply with some samples or links,please...

Asuming m_Combo1 is the variable of class CComboBox try
int tLen = m_Combo1.GetLBTextLen(m_Combo1.GetCurSel()); m_Combo1.SetEditSel(tLen,tLen);I hope it helpsthankyou for kind reply, But it was not working...

try this, it work for me. In a MFC dialog app , add a ComboBox, add a control variable m_Combo1 for it. in the CBN_EDITCHANGE message map the metod: OnCombo1EditChange In the body copy the folowing code
void CMFC1Dlg::OnCombo1EditChange() { // Here you should do or call the process to look for text on the DB // and modify the ComboBox item list and text //for this examle //Here I get the text entered and compare it whit a fixed text "New" //If the user entered "New" and not exists the item "New Element" in //the combo list, I add de element //then select the "New Element" item as the current selected item // Set the cursor at the end of the element // // For a real use, I think, is better select the text since the // last entered character to the end of the text // CString UserText; TCHAR AddText[12] = _T("New Element"); CWnd * pEdit = m_Combo1.GetWindow( GW_CHILD ); ASSERT( pEdit ); pEdit->GetWindowText(UserText); if ( UserText.Compare(_T("New"))==0) { if (m_Combo1.FindString(-1,&AddText[0])==CB_ERR ) { m_Combo1.AddString(&AddText[0]); m_Combo1.SetCurSel(m_Combo1.FindString(-1,&AddText[0])); } int tLen = m_Combo1.GetLBTextLen(m_Combo1.GetCurSel()); m_Combo1.SetEditSel(tLen,tLen); } }//Note CMFC1Dlg is the class for the dialog Or take a look at: http://www.codeproject.com/combobox/combocompletion.asp -

thanks for your post, this may be useful for me in future. BTW, can you suggest me some technique in code project such that i can mark my favourites (like that of yours) such that i can refer them in future? thank you.

Since i have to Reset the condent of the combobox for the previous value, can u tell me tsome way to sort it out???? void CBillingDlg::OnEditchangeProductID() { int vv=m_ProductID.GetCoun();//m_ProductID //is my variable for combo box CString var; CString xx; m_ProductID.GetWindowText(var);//getting text// xx=var; var=var+'%'; m_ProductID.ResetContent();//Foe clearing the previous values// m_ProductID.SetWindowText(xx); /*Below Code for accessing the database*/ CString query; query.Format("Select ProductID from Product where ProductID like '%s%%'",var); TCHAR sz[1024]; sprintf(sz, query); char *ptr=sz; bas obj; spring++; int i=obj.ProductName(ptr,"ProductID"); for(int peek = 0;peek||SnAkeBed||

The easy way set the sorted property of the ComboBox to true, if the sort order is defined by the text in the list. If not the easiest way is to add an “Order by” in the Query. Assuming the Data source supports it (i.e. Any ANSI SQL DB), and the ordering key is accessible in the query. If the order needed is not defined by the data returned or accessed in the query you need to sort it manually, i.e. loading it into a vector or array, ordering the array with any sorting method (bobble, fast sort, hash tables ...) Then insert the values from the ordered array.

thanks for your reply, but will the permalink adds the post to my favourites? what i mean is, i should be able to see my favourites from any system. can you suggest in this regard? and replying tthe interested post and finding them in my posts from my profile page will also do. but i would have to reply them saying "thank you and your post is useful for me in future" which occupies unnecessary space in CP and this may also be in convinient to some members. thank you.

Yes, make a try... if you use search for a message, there will be "?" and "search" keywords in the url on the navigator when you go to the selected one. But once you are in the message, if you press "permalink" then the navigator autoupdates itself and in the toolbar you will have an URL in absolute mode with the code ID of the forum and message. So if you add it in favourites or copy paste in a txt you will have the url to the message, although the board grows a lot. I make it that way, take the permalink and then write down a short description in a txt, adding the link at the end. So I have the direction and something that helps me find the one I need.
