Simple but very confusing to me Kron of LS14-Jul-01 8:35 Kron of LS 14-Jul-01 8:35  I need to create a dialog based app that does basically one thing, calculate the total pay from 2 fields -i have 3 edit box's, 1 for hours worked, 1 for pay rate and the third for the total pay. -what it has to do is take whatever numbers i put into the first 2 fields, then by clicking a button multiplay them together and put the answer into the third field. i've seen calculation code for console based but it looks completely different then what i use for dialog. i know it must be simple but to me as a beginner, it's rather confusing. please help Re: Simple but very confusing to me 14-Jul-01 20:51 14-Jul-01 20:51  Since you have a console app that performs the desired function your problem then seems to be how to get the numbers from the edit boxes and put the result into the third edit box. Look at the documentation for Dialog Data Exchange (DDX) and UpdateData. Re: Simple but very confusing to me Steve T16-Jul-01 9:59 Steve T 16-Jul-01 9:59  Kron, I'm not sure what parts you are finding confusing but the app you want is so simlple here's a quick walkthrough of how to make it in Visual C++; (No I/O control or formating/error checking etc) You should be able to spot where you went wrong. Create a new Project - MFC AppWizard (exe) Add the 4 controls you need ... 3 edit boxes and a button Right click each one in turn and in their properties/general change the IDs to : IDC_HOURS IDC_RATE IDC_PAY IDC_CALC (for the button) Now again right click one o fthe controls again and this time go to the ClassWizard. For the 3 edit controls you want to add a variable and associate it with the edit box: In ClassWizard select the "Member Variables" tab then - ( example for "Hours" box... ) Highlight "IDC_HOURS" in Control IDs column. Click "Add Variable" Complete Member variable name as "m_Hours" Make sure "Value" is selected in Category drop-down list. Select "float" in "Variable Type" drop-down list. Click "OK" ...do the same for IDC_RATE and IDC_PAY Controls IDs. Now select the Message Maps tab on the AppWizard. Highlight IDC_CALC in the Object IDs list Highlight BN_CLICKED in the "Messages" list Click "Add Function" Click "Edit Code" This will take you to the code at the newly created ::OnCalc()function. Here insert the 3 lines: UpdateData(TRUE); // the above line transfers the input typed in the IDC_HOURS // box and IDC_RATE box into the variables m_Hours and m_Rate m_Pay = m_Rate * m_Hours; // This does the work UpdateData(FALSE); // This causes newly calculated contents of m_Pay to be // displayed in the IDC_PAY edit box. Compile and run! Hope that helps. Steve T. thnx for the help, it worked Kron of LS17-Jul-01 10:03 Kron of LS 17-Jul-01 10:03  i dont know why but my teacher seems to think i should know this stuff already when he hasn't even explained floating point yet for decimals. i had to buy a book and find it there. another problem i'm having with this is, i have to now put in 2 more edit fields for name and lastname and make a button that clears ALL fields. i thought i had it but i get an error telling me it can't convert str to float and vice versa. is there a universal clear command that clears all fields in the program regardless of the contents? Re: Simple but very confusing to me fantastic_mr_fox23-Jul-01 2:35 fantastic_mr_fox 23-Jul-01 2:35  1. Create a new project under VC++ using the project wizard and make it a dialog based application. 2. Go into the resource and add the edit controls you need and a button to multiply. Use names such as IDC_EDIT_RATE, IDC_EDIT_HOURS and IDC_EDIT_RESULT for your edit boxes. 3. Go into classwizard and to the 'member variables' add a new variables to the controls. This gives you an easy way to get to the data in the edit controls. So you should create some variables such as m_editRate, m_editHours and m_editResult. 4. Goto the 'message maps' tab again in classwizard. Select the button control from the list onthe left. Select the BN_CLICKED message, and create a function called OnButtonClick(); 5. Goto this function in the code and add the following: ---------------------- CString sRate; m_editRate.GetWindowText( sRate ); CString sHours; m_editHours.GetWindowText( sHours ); CString sResult; m_editResult.GetWindowText( sResult ); float fRate = atof( sRate ); float fHours = atof( sHours ); float fResuls = fRate*fHours; CString sResult; sResult.Format( "%f", fResult ); m_editResult.SetWindowText( sResult ); ---------------------- You'll have to include the right header to use atof() (see the help file).. I can't remember it offhand. Well I hope that will get you started.

Is there a color code # I can use to achieve transparency for the background color of this search box so it will match the rest of my page? Thanks in advance. Re: Help Needed For Simple Problem 14-Jul-01 20:52 14-Jul-01 20:52  No Re: Help Needed For Simple Problem Nikhil Dabas15-Jul-01 8:09 Nikhil Dabas 15-Jul-01 8:09  If you can use an IE-specific solution, create a DIV and set it's contenteditable attribute to true - that'll make it work like a textbox. It's background is transparent by default, so you don't have to do anything more. You shall have to get what the user entered from its innerText property. see the sample below... If you have IE 5.5 or better, you can edit this text.

This should support IE versions from 4.x to 5.5 and windows 9.x,NT,Me,XP. Is there any win 32 API or ready made code example for this Plz..... i need it very urgently... Thanx in advance archana archana kirane Sr. Software Engineer Re: deleting IE history folder contents 14-Jul-01 20:54 14-Jul-01 20:54  How much is the code worth to you? Re: deleting IE history folder contents Shaun Kaasten14-Jul-01 21:24 Shaun Kaasten 14-Jul-01 21:24  Check out the IUrlHistoryStg2 Interface Re: deleting IE history folder contents 15-Jul-01 7:23 15-Jul-01 7:23  Does not meet the requirments. IUrlHistoryStg only works for IE 5.5 or above and WinMe & Win2K or above. Re: deleting IE history folder contents Shaun Kaasten15-Jul-01 8:28 Shaun Kaasten 15-Jul-01 8:28  I think MSDN's documentation is incorrect there. Those interfaces have been included since visual studio 6. I've been able to use them on Win95 and IE 4.0 (I think). Re: deleting IE history folder contents archana15-Jul-01 19:07 archana 15-Jul-01 19:07  Is it so? as i tried with the IUrlHistoryStg2 with WinNT4.0 and IE 5.5 but it not working . Below is the code i tried. IUrlHistoryStg2 * pHistory; HRESULT hRes; CoInitialize(NULL); hRes = CoCreateInstance(CLSID_CUrlHistory, NULL, CLSCTX_INPROC_SERVER, IID_IUrlHistoryStg2, (LPVOID *)&pHistory); if (SUCCEEDED(hRes)) { pHistory->ClearHistory(); pHistory->Release(); } CoUninitialize(); return hRes; what could be the problem? thanx and rgds archana Re: deleting IE history folder contents Shaun Kaasten15-Jul-01 20:17 Shaun Kaasten 15-Jul-01 20:17  This code looks good to me. Is it the CoCreateInstance or the 'ClearHistory()' that fails? Re: deleting IE history folder contents archana15-Jul-01 23:35 archana 15-Jul-01 23:35  ammm one doubt is there... do "today" folder should also get cleared using this method???? As, in my case it's not getting cleared. And i need to clear it. Thnax in adv. archana Re: deleting IE history folder contents Shaun Kaasten16-Jul-01 10:34 Shaun Kaasten 16-Jul-01 10:34  I'm not sure why the 'today' folder wouldn't get cleared. I guess you could use IUrlHistoryStg to enumerate and delete the URLs that remain, but that seems like overkill. Re: deleting IE history folder contents archana16-Jul-01 19:40 archana 16-Jul-01 19:40  well, i think it was the problem as my browser instances were open. I will tackel that now. Could u tell me something .....changing the subject bit Now it's about deleting History files for Netscape 4.7 and 6.0 . My research told me that...NS 4.7 saves it's history in netscape.hst in user profiles but i didn't get any file of named netscape.hst in NS 6.0 instead i got history.dat but it is not containing URLs. So, do u know where actually NS 6.0 stores it's visited URLs . Is it cookies.txt? I doubt but...and even it stores it's entries in the address bar(drop down combobox) in different way or in different location i think...i didn't get that also....if u know details of NS 6.0 history files then plz do let me know... Thanx in advance archana Re: deleting IE history folder contents Shaun Kaasten17-Jul-01 20:44 Shaun Kaasten 17-Jul-01 20:44  I'm afraid I don't know how to access Netscape's history info.

Erik Yuzwa12-Jul-01 11:16 Erik Yuzwa 12-Jul-01 11:16  Hi, I'm in search of a sample of creating a MAPI preprocessor. I've taken a look at the one in the Platform SDK, but am a little confused as to what *basics* I need to have done.. The same preprocessor in the SDK is full of a lot of stuff which might probably be unneccessary for what I want to do.. thanks in advance, Erik I hit faked him with my win32 API .chm and the peabrain goes for it.
