Adding icon to desktop & create a startup entry ? hongheo7620-Jul-02 5:13 hongheo76 20-Jul-02 5:13  Hi, I am a newbie in VC. Can anyone instruct me how to install a icon for a program on the desktop, and later delete it (in Visual Basic or Visual C++) ? Besides, if I want to make my program automatically run when Windows starts, I will have to create an registry entry for HKLM\Software\Microsoft Windows\..., how should I create such a key using Visual C++ ?

Such as, typedef struct { int x; double y; unsigned char name[128]; ........ }MYSTRUCT; and then, i use this struct with global two-dimentional array like this; MYSTRUCT mystruct[300][500]; With this definition, there is no memory allocation fot it. My problem is how to free the memory or delete it when it is not used or application will exit? Thanks in advance! chen Re: Search a proper method for free and delete a struct array? Michael Dunn20-Jul-02 6:37 Michael Dunn 20-Jul-02 6:37  I'm not sure what you mean by "there is no memory allocation fot it." That declaration creates a 2D array with 150,000 elements total. Since it is a global, the memory is freed automatically when the process exits. --Mike-- Just released - RightClick-Encrypt v1.3 - Adds fast & easy file encryption to Explorer My really out-of-date homepage Sonork-100.19012 Acid_Helm ATL/WTL vs MFC rsasalm_20-Jul-02 3:57 rsasalm_ 20-Jul-02 3:57  Hi all, I have a basic question. I want to write a GUI application and I have to choose between ATL/WTL and MFC. Which one should I choose and why? I just compiled an wizard Dialog-based application with both WTL and MFC and the resulting generated code and *.exe for WTL is bigger than MFC, my guess was opposite why it is so? any help in this regards regards /rsasalm Re: ATL/WTL vs MFC Tim Smith20-Jul-02 4:13 Tim Smith 20-Jul-02 4:13  Actually, there is little chance the executable for WTL is larger. What you are missing is that the MFC version requires the MFC DLLs. These DLLS must be distributed with your application to insure that everyone can run your software. I am a huge fan of WTL. But in many ways it is more basic than MFC. But that also means that it doesn't get in your way as much as MFC. IMHO, more experienced programmers should move to WTL. But if you are just creating applications that fit well with MFC, it works just fine. It is really hard to say which would be best to use.

Hoare - 1980 ACM Turing Award Lecture Hiding an application from the average user. Anonymous20-Jul-02 2:21 Anonymous 20-Jul-02 2:21  I have an SDI application with a single CformView view. I only want the view to be visible in diagnostics mode. Otherwise it should be invisible to the user. I can hide the app with CMainFrame::m_pMainFrame->ShowWindow(SW_HIDE); In the OnInitialUpdate(). But the app still shows up and then goes away. Is there a way to hide it either sooner or all together so the average user never sees it? Thanks Re: Hiding an application from the average user.

User Authentication laphijia20-Jul-02 2:19 laphijia 20-Jul-02 2:19  How can I authenticate a user in a n-tier application made of a C# Client, a XML Managed C++ Web Service and an SQL Server Database. The database is 2 tables with each rown contains: the users table contains the columns: -username -password the personal data table contains the colums: -username (with a relationship with the first table) -name -surname -address -phone The XML Web Service consists of two methods: Login(username, password) GetData(?) UploadChanges(?) Now It's start to be confusing for me! I want that only the correct user, authenticated using the data in table Users, can modify the corresponding row in the PersonalData table. How I accomplish this? I could setup a cookie like mechanism that asks username and password, gives them to the Login() method, that returns a SessionVariable, and stores them in the PersonalData table. After when a user wants to GetDataFromDatabase of UpdateChanges, it has to give the variable back, and the update is made with a SQL statement like (SELECT FROM PersonalData WHERE CurrentSession = XXX) Is this method reliable? Is there a simpler method that I don't know? Is there any kind of serverside security? Maybe in the SQL Database? Thanks to anybody who will answer me.

For example, on the page where they can edit their details, you could change it so that it will only fill out the form with details from the DB where the user + pass = what was entered. By doing a join with the two tables you can return all the information in one query, and by filtering it this way if the pass or username is wrong, it won't be returned. Likewise when returning the data back, only update the rows where the user + pass match, for example create a view which joins the two tables (in effect returning user details) and limiting it based on user + pass. Another way is to store the username in a cookie, as well as a hashed version (with some random text appended). Then, everytime a page is loaded, check that the hashed value matches a hash generated at the time the page is executed. This way, you can be sure that its been issued by you, and not hacked. Then you just have to check its a valid username, if it is, then all is well. Let me know if there's something I need to explain a little better. Create compoent to be used in IE Anonymous19-Jul-02 22:55 Anonymous 19-Jul-02 22:55  Can anyone tell me what are the steps to create components that used in IE (without GUI, just like ADO components) ?

I tried creating a COM control 2 years ago using VS6, but now completely forgot all the stuff. When I created a ATL Project, it has two projects created, one is MyProjPS and the other one is MyProjPS (supposed to be proxy & stub, right). Then what's next, I should right click on the MyProj and choose Add-New Class, right ? Then what should I choose from the ICONS ? What next then ? ... I forgot the steps ... Re: Create compoent to be used in IE Anonymous20-Jul-02 4:00 Anonymous 20-Jul-02 4:00  Let me specify more in details. I created some MFC classes in a DLL for sending some message to a server. Now, I want to wrap the classes with COM, so that they can be used in VB clients and ASP. But I just don't know how to do so. Should I choose Add->New Class->ATL support to my existing MFC DLL, or create a new ATL project to support MFC and create new com classes call my classes.

Hope u got something.... If not explain again.... cheers, Super ------------------------------------------ Too much of good is bad,mix some evil in it Re: activex installers... Anders Molin20-Jul-02 13:23 Anders Molin 20-Jul-02 13:23  InstallShield makes a "Install From Web" thing that works fine. You can also write your own ActiveX Component, "embed" it in a webpage, and let the component download and install the software. If you make your own, you just have the problem with signing it, a certificate for signing is expensive, and most people will not run an unsigned ActiveX Component... - Anders Money talks, but all mine ever says is "Goodbye!" VC 7.0 migration unknown soldier19-Jul-02 21:18 unknown soldier 19-Jul-02 21:18  I've migrated to VC 7.0 few minutes ago and naturally having some problems. In VC++ 6.0, there is a "project" menu that contains the "settings" item. Right !!!. If we click it, a property dialog appears which contains among many tabs, a "Link" tab. Here we give the path of various run time libraries. Now how can we achieve this using VC++ 7.0
