Containers of what? If you have containers of string's, try FeinEvaluatorPro form FeinSoftware (www.FeinSoftware.com).

This is my first real exposure to Unicode Base64 Binary data-types; in so far as having to actually deal with them myself. So here's the break-down:
I have a data value that is stored as an encoded Base64Binary. I decode this data value, using a small C routine, and end-up with a string value such as "base64:RGHHGH ..."
I now want that value converted as it's actual STRING data type (the actual data is a GIF image).
Can anyone supply me with the steps, code, function necessary to accomplish this task? I MUST keep this compliant through Windows 98, so please keep that in mind.
Thank you in advanced for any help

since you want to convert it to actual STRING, i would like to know what is the current data type??

Excuse my misuse of data-type terminology, since it is currently a char* value.
I've decoded the Base64Binary into a char* that now holds the data as "base64:..." this, however, is still not correct, since the actual data is a GIF image (e.g., "Gif89 ..."). In C#, once decoded, I would then use the AsciiEncoding.GetString() method to get the 'string' result of this data value.
I need a C++ equivalent of that C# function.

Whell char* is a string,
if you using MFC then you can do this
CString strText;
strText = decodedstring;
or check out string of STD::String, i have not used it so little idea bout it. but still the current data type is string too.

Either I'm not explaining myself clearly or you're not understanding the context of the actual problem. I know what a string is, as char*, string and CString; that is not the issue at hand. My problem lies with a Base64Binrary data-type that, when converted through a MIME decode algorthim, decodes as "base64:RG0...." and not back to it's original data value (which should be a GIF image). I am therefore seeking the algorthim to handle the second portion of the decode, or one that will convert the data back to it's proper format through one-pass.

Hi,
I have a classic Win32 DLL (including it's sources), which is imported into project implicitely.
Can I somehow control the path from where the DLL is loaded, while leaving the DLL import implicit? (i.e. not use the default LoadLibrary strategy)

humm,Well i am not giving you a solution just a thought though.
you mean to say that if there are 2 different versions of the same dll in the path then you want to control which dll to load, rite???
If I got that rite, then i guess that exactly is one of the problem why COM evolved.

Yup I know... But the interface is *very* Win32, and I don't want to convert it to COM. I was thinking of the same way, more or less.
Actually, the Win32 way would be acceptable for the release, but I'm looking for a solution during debug...

humm, Seems like there is no easy workaround otherwize you would have already got it.
I understand ur prob, during development this kinda prob arises. How i have done is that the dll should not be in any path instead it's binary output should be in the same directory of the output path of the host binary file(I assume the host is also developed by you).
This way if the host binary is diff, say debug or release, then appropriate dll will be loaded.
Well i dont know the sol that you are asking for, but i guess its just a precaution that need to be taken to avoid versioning problem,
I also time n again search for the dlls (development ones) in the root project folder and delete them.

i have created a dialog windows application using the app wizard.
it has a few other sub dialogs which are created from code behind file menu bar.
Im looking for a method to get access the main dialog windows data from the other sub dialogs.
im sure their is any easy way to get a pointer to the data ?
|
|
|
|
|
if the data is in the main dialog class, you need to pass a pointer of that dialog to the sub-dialogs.

Hello,
GetParent() returns the main dialog pointer.

I would like to create several rectangles overlapping each other but having a transparent look. How can I achieve this by not using bitmaps but regular GDI functions, such as Rectangle(), etc.
Thanks

Might help: "An application sets the foreground mix mode by using the SetROP2 function and retrieves the current mode by using the GetROP2 function."
These are only for binary raster ops though. Not sure how you would control the mix amount with a setting for alpha blend amount.

Hello,
The best way for playing .MP3 and .WMA files is DirectShow
There's many libraries on the internet that could do it too.
I'm sure that you can find some samples about playing mp3 files from CP site. ( i saw some good audio players and etc. )
hmm, MCI is another way

Hadi

Hi,
I am writing an application, which does some monitoring work. Here I have to include two buttons and a list box. Now I have to trap the WM_KEYDOWN/ WM_KEYUP messages and scan the contents of the list box. Can provide me some help in this issue?
|
|
|
|
|
Using ClassWizard, select the name of your listbox class in the Class name: combobox. In the Messages list, select WM_KEYDOWN. Click the Add Function button. Do the same thing for the WM_KEYUP message. Populate the message handlers as you need.

Hi guys
I developed an application in MDI,
I want to know .. i open an new document and close it.. the memory for that document be released...i checked in task manager , it dosent show any release of memory..how shld i find out or wat functions shld i call to release the memory for the document
Thanks
krithika

TaskManager may not show any change; the memory may be in a heap ready for your app to reuse, but the heap itself has not been shrunk.
The framework will use DeleteContents(), which should clear any member variables in your document.
If you exit, then a debug build will generally show you common memory leaks if you're running under a debugger.

Hi everyone !
Is there any way to wait for a callback function like the HookProcs ?
Thanks in advance,
André Schmidt
|
|
|
|

Huh?
What do you mean by 'wait for a callback function'?
Do you want an indication when one is called?
(If so, the function could signal an event)
Do you want to wait until a callback has returned?
(doesn't this happen anyway?)
