Thanks for the reply. : ) I am not too sure where to set the modal dialog parent to the dialog? How to reference or get a handle in the parent dialog? [IShellView2] how to remove the web view ? luc26-Oct-02 1:18 luc2 6-Oct-02 1:18  i've implemented an IShellBrowser, created an IShellView2 with CreateViewObject, but when i create a window with CreateViewWindow2 to display my files, i also get the "web view" on the left of the window. i tried to remove it with FWF_NOWEBVIEW in FOLDERSETTINGS.fFlags, but the web view is still there... how to remove it ? URL Encoder John Bosko5-Oct-02 22:37 John Bosko 5-Oct-02 22:37  Hi, Please can someone tell me, where do I get the URL Encoder for C++. Many Thanks, John Re: URL Encoder Dominik Reichl6-Oct-02 1:20 Dominik Reichl 6-Oct-02 1:20  Err... what the hell is an "URL Encoder"? Could you give an example what it should do? -Dominik Re: URL Encoder John Bosko6-Oct-02 1:22 John Bosko 6-Oct-02 1:22  Hi Dominik, Apparently I want to encode a string in C++ and then store the same in a char field. Thanks, John Re: URL Encoder Dominik Reichl6-Oct-02 1:27 Dominik Reichl 6-Oct-02 1:27  What does "encode" mean in this context? Re: URL Encoder John Bosko6-Oct-02 1:49 John Bosko 6-Oct-02 1:49  Encode would imply parsing a string with values. ex. if the string was www.yahoo.com before encryption, after encryption it would be something like www&&yahoo^com. the characters would be replaced. Re: URL Encoder Dominik Reichl6-Oct-02 1:58 Dominik Reichl 6-Oct-02 1:58  So you need a function which does the same as the function escape("") in JavaScript? I don't know any existing source which does this. But it should not be that hard to replace some characters with some other, especially if you use CString or STL strings. Re: URL Encoder John Bosko6-Oct-02 2:16 John Bosko 6-Oct-02 2:16  Yes, I need something like escape in java!!! Please can you help me out with it, I am pretty newbie in C++. Thanks Dominik, John Re: URL Encoder Dominik Reichl6-Oct-02 2:31 Dominik Reichl 6-Oct-02 2:31  The easiest way is using CStrings. Create a CString object and copy the string you want to encode in the CString. CString str; str = "www.yahoo.com"; Now, replace all the characters you want to encode. str.Replace(" ", "%20"); This would encode all spaces to the correct %20 code. Now you would have to do this for all characters... For all codes see the following sites: http://www.macromedia.com/support/flash/ts/documents/url_encoding.htm[^] http://www.blooberry.com/indexdot/html/topics/urlencoding.htm[^] http://ops.tamu.edu/nipsy/url/common_encodings.html[^] -Dominik Re: URL Encoder carrie6-Oct-02 8:15 carrie 6-Oct-02 8:15  Just as an aside through boredom theres also encoding of IP addresses. Its pretty stupid but quirky in a bored sort of way. Its basically turning each decimal octet into a hex string or octal string. You can find out about that here - http://www.pc-help.org/obscure.htm#hexip boredom is a bad thing on a board like this Re: URL Encoder Anders Molin6-Oct-02 10:56 Anders Molin 6-Oct-02 10:56  Use the InternetCanonicalizeUrl() function - Anders Money talks, but all mine ever says is "Goodbye!"

I was hoping to use OnCreate() but it appears its child controls aren't created yet and the app asserts. I'm currently initializing controls in DoDataExchange() using the following little hack to prevent multiple inits for each control. static BOOL bFirstPass=TRUE; if(bFirstPass){ .. Do init bFirstPass=FALSE; } Any other betters ways of accomplishing this task...? Thanx!

I have in the past got SetLayeredWindowAttributes() to work by defineding _WIN32_WINNT 0x0500, but I can't seem to get it to show itself this time. I am getting errors saying it's undefined or unidentified along with WS_EX_LAYERED & LWA_ALPHA. Am I missing something?! I feel like I am but I just haven't been able to figure it out? I have tried it out on two different compilers (Dev-C++ (open source) & VC++ 6.0 SP 5), but same thing arises. Thank for any comments/suggestions, Kevin Power, Jr. Re: SetLayeredWindowAttributes Problem User 66586-Oct-02 1:19 User 6658 6-Oct-02 1:19  Make sure you have installed the latest Platform SDK and set up the paths in your VC IDE. regards Greg modified 12-Sep-18 21:01pm.

Sunny Schema version change has no effect work_to_live5-Oct-02 18:13 work_to_live 5-Oct-02 18:13  I realize this is a pretty vague discription of a problem, but thought it might ring a bell with some of you... I created an MDI application, serialized the data, and everything was going well. Then I tried some hostile testing by incrementing the schema version number, and instead of the CArchive object catching the difference, and presenting me with the "document out of date" dialog box (or words to that effect), the document loaded an older version of the data, and proceded to crash. Having just returned to Windows development, I thought this might be symptomatic of a setup problem of the serialized objects. It's obvious that the schema is being saved, since I can successfully load the saved document if I change the schema back to the original value. I even tried to catch a CArchiveException, but to no avail... Anything come to mind? I verified that the methods used paralled those in Scribble, but for all I know, I might be missing a vital ingredient. Thanks. If more information is needed, I can provide it, but thought this might be symptomatic of an obvious setup problem. Obvious to everyone but me! Re: Schema version change has no effect Steve S7-Oct-02 3:48 Steve S 7-Oct-02 3:48  There's a flaw, in that if you have a base class and there are derived classes, retrieving the schema in the base and derived class serialize methods will cause a problem. I typically code around this by not using the MFC concept of schemas, and in each call to serialize, emitting a version byte. It sounds like overkill (and with a lot of objects, can inflate the amount of disk required), but it's not failed me yet. This lets me always write using the latest version, but read any with code like; if (ar.IsLoading()) { BYTE version; ar >> version; // Do stuff that hasn't changed... ... if (version > MAXOBJVERSION) { // throw a CArchive exception here! } if (version > 0x01) { // Do version 2 and later stuff... } } Steve S [This signature space available for rent] how to uninstall a software programatically ? imran_rafique5-Oct-02 16:45 imran_rafique 5-Oct-02 16:45  how to uninstall a software programatically ? r00d0034@yahoo.com Re: how to uninstall a software programatically ? paracha35-Oct-02 18:38 paracha3 5-Oct-02 18:38  if the software appears in add/remove program then you can go to registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and look for uninstallString key.
