http GET/POST request through proxy Chintan1-Dec-02 23:59 Chintan 1-Dec-02 23:59  Sir, my computer is running under the proxy server. I want to developed application which is able to make http GET and POST request to a specified server. C.R.Naik Re: http GET/POST request through proxy rrrado2-Dec-02 0:35 rrrado 2-Dec-02 0:35  Send GET/POST as usually, instead that you will connect your socket to proxy server instead of HTTP server. Headers will remail the same, in simple case (no proxy authorization ...) rrrado Re: http GET/POST request through proxy geo_m2-Dec-02 2:38 geo_m 2-Dec-02 2:38  good behavior is also to send the complete url of the request, which is not necessary when using direct connection. Instead of <br /> GET /index.htm HTTP/1.1<br /> Header: Value<br /> which is allowed for direct connecting, you should use the full syntax: <br /> GET http://www.codeguru.com/index.htm HTTP/1.1<br /> Header: Value<br /> from this the proxy will be able to know, where you want to connect Minimize to task bar rrrado1-Dec-02 23:26 rrrado 1-Dec-02 23:26  I have modeless dialog windiw created in separate thread. Clicking to minimize button cause shrinking this window to size of title bar and it moves to bottom left corner of rhe desktop. How to minimize this window to task bar ? And show this window in task list so i could switch to this window by Alt+Tab ? Thank you rrrado Re: Minimize to task bar Paul M Watt2-Dec-02 9:53 Paul M Watt 2-Dec-02 9:53  It sounds like you are using the WS_EX_TOOLWINDOW style. What you will need to do is remove the WS_EX_TOOLWINDOW style in the SC_MINIMIZE portion of the WM_SYSCOMMAND message handler, and restore this style setting when the SC_RESTORE event is received in the WM_SYSCOMMAND handler. The toolwindow prevents your windows from appearing in the Taskbar, however it also makes your windows minimize to the desktop like you have described.

Re: Minimize to task bar rrrado2-Dec-02 22:25 rrrado 2-Dec-02 22:25  I'm not using WS_EX_TOOLWINDOW style. It is ordinal dialog box window, i tried popup and also overlapped type, without any extended styles set in resource editor. rrrado Re: Minimize to task bar Paul M Watt3-Dec-02 6:00 Paul M Watt 3-Dec-02 6:00  Could you view your windows styles in Spy++ and let me know which styles both regular and EX that your window is using? That would help me figure out whats causing your problems. Thanks Build a man a fire, and he will be warm for a day Light a man on fire, and he will be warm for the rest of his life! Re: Minimize to task bar rrrado3-Dec-02 7:23 rrrado 3-Dec-02 7:23  Dialog style : 14CF0044 (WS_OVERLAPPEDWINDOW|WS_VISIBLE|WS_CLIPSIBLINGS|WS_OVERLAPPED|DS_3DLOOK|DS_SETFONT) EXTENDED STYLES : 00010100 (WS_EX_LEFT|WS_EX_LTRREADING|WS_EX_RIGHTSCROLLBAR|WS_EX_WINDOWEDGE|WS_EX_CONTROLPARENT) Parent window : NONE ( created with NULL parent window) Thank you. PS I create more ot this modeless dialog windows, each in separate UI-thread. Another bug is that sometimes more of them are dreawn with active title bar, like when all of them would have focus set. So after creating of dialog i set focus for it, but it still happens rarely. Thank you rrrado Re: Minimize to task bar Paul M Watt3-Dec-02 8:09 Paul M Watt 3-Dec-02 8:09  It looks like if you add the WS_EX_APPWINDOW style you will be all set! Good Luck Build a man a fire, and he will be warm for a day Light a man on fire, and he will be warm for the rest of his life! Re: Minimize to task bar rrrado3-Dec-02 22:39 rrrado 3-Dec-02 22:39  I tried to set WS_EX_APPWINDOW style, now it is in task bar next to main window, but windows is not able to switch to main window, it always switch to my dialog even if i click to main window in task bar I will perhaps write my own window switching wihtin my application with ctrl-tab.

Adding Folders to the Projects in the Workspace Franz Klein1-Dec-02 21:00 Franz Klein 1-Dec-02 21:00  :Does anybody know how to add folders to a project, so that it gets displayed in the workspace on Visual C++ 6.0. I know one can do it with the mouse, but I want to have my AppWizard do it according to the options the user has chosen. Are there any functions that I can call. The only other way is to parse the .dsp file and add the folders there. Franz Klein CryptEncrypt devvvy1-Dec-02 19:56 devvvy 1-Dec-02 19:56  hi, having trouble debugging my lil subroutine that encrypt and decrypt a buffer. algorithm used is RC2 (8 BYTE PER BLOCK). HKEY derived from a passwd with MD5. API used: (a) CryptEncrypt (b) CryptDecrypt The plaintext buffer going INTO CryptEncrypt was 28 BYTE (This means that u will have to call CryptEncrypt four times). The number of bytes in the returned encrypted buffer is 40 BYTE. Now, i know that the encrypted buffer may be "up to a block size" larger than the plaintext buffer (according to MSDN). Since I called CryptEncrypt four times, the encrypted buffer can be as large as: encrypted buffer size = 28 BYTE + 4 x 8 BYTE = 60 BYTE QUESTION 1: Is this understanding correct? QUESTION 2: * RC2 used - 8 BYTE per Block. * plain text buffer = 28 BYTEs * return buffer = 40 BYTEs (Is this reasonable?) Thanks. norm Re: CryptEncrypt devvvy1-Dec-02 20:43 devvvy 1-Dec-02 20:43  FACT 1: btw, just want to let you know that the error was: (a) NTE_BAD_DATA (b) seems like the length of the encrypted buffer is shorter than it should be and in the "final" pass - decryption - the buffer to be decrypted was NULL - thus leads to NTE_BAD_DATA. FACT 2: however, NO error was reported from CryptEncrypt. CryptEncrypt was called a few times to encrypt a buffer prior to calling CryptDecrypt. HOWEVER, the returned buffer does seems to be shorter than the indicated 32 BYTE (NOT 40). I can tell this by looking at the watch windows - but special characters in the encrypted buffer may cause to the situation in which not all byte/char in the encrypted buffer to be displayer. But i does look a lot shorter than 32 BYTEs FACT 3: my decryption subroutine (which wraps around CryptDecrypt) successfully decrypted the first pass/block. Then from second block on, decryption was done, but I can see that it decrypted wrongly. I cannot isolate the fault - the error may be on the encryption side, i may very well be on decryption side. Thanks norm How can I multiple single instance application ? AhMan1-Dec-02 18:12 AhMan 1-Dec-02 18:12  How can I multiple single instance application ? Thank you for your kindness Re: How can I multiple single instance application ? geo_m2-Dec-02 2:47 geo_m 2-Dec-02 2:47  Hi, If I understood, you have some app, limited to be single instance and you want to run it simultaneously. This is usually done by the creating some system-wide named resource, created by the first instance. Then other instances only check, if there such a resource exists. If yes, they exit immediatelly. So in a generic way, you must avoid the second instance to find that resource, or remove the checking part of code. But here I must mention, that this can have unpredictable results. At first, the designers of the app usually have some reason for implementing such a feature, second reason, forcing to close some handle, which application thinks is still open, may lead to crashes or some other odd results.
