im looking for a way to read zip files from a C++ application, preferably without using a third party library. Windows ships with two dlls (LzExpand.dll and lz32.dll) that apparently give the ability to read compressed files but not zips. Thanks in advance.

Im looking for information on extracting the contents of a text file contained within a zip file. All I need to do is read the contents out, no modifications will be made so the simpler the better. Thanks in advance.

Java can perform at speeds that should be adequate for almost any application. I have written several Java applets and applications in Java for which execution time was a major concern and was always able to get sufficient speed out of Java. With careful optimization your performance needs can...

When you create an instance of an object it does effectively create an instance of every class from which it inherents. This makes it a little slower to instantiate than simply instantiating one large class. However, do not completely avoid inheritence because of speed. Correctness is...

Java wont reclaim memory until you run out of it. You can manually kick start the garbage collector using System.gc() from memory. Be warned that this may cause the system to grind to a halt for a few seconds so be careful when you call it. Threads are far more likely to cause the kind of...

I have noticed that using the method for checking for user input used in most example code, ie IF INKEY()=whatever, only allows for one key to be pressed at a time. Although the special keys seem to be excempt from this if you use IF LEFTKEY()=1 it is still anoying that only one alphanumeric...

Try the code below. I think the problem might be the placement of the <% %>. Its my understanding that blocks of code like and if else must be contained in one block. Im not sure if the sytax of the println is correct. There is a command which prints a line to the html document, you'll have...

Try giving the server a name in its network settings and using that in place of localhost. That might work.

Anyone got any good suggestions as to where I can get a decent free editor for X files?

Thanks, yeah I just needed to set the location of db in the options. For some reason the readme contains lots on version bug fixes etc but no installation instructions.

I consider myself to be a reasonably clever person but i cannot, for the life of me, get darkEdit to compile in any form. If you have opened a dba file and you click compile it brings up a msg box saying &quot;Error running Core&quot;. I assume this means it cannot find darkbasic. Dark basic...

The output of a JSP is simple text regardless of its content. Have the JSP selectively include VRML code to suit your needs. The simplest example I can think of is when you want the VRML to contain one of two objects but not both. Use an if statement in the JSP and have two branches which...

I am using a server object within an RMI application. It extends java.rmi.server.UnicastRemoteObject. Its function is to remain memory, servicing RMU method calls, until a particular signal from the client indicates that the communication is complete at which point the object should destroy...

I am writing and an applet/servlet which will communicate data via the Internet. Can anyone point out any good sites or books that deal with security in this contex?. Most books etc deal with protecting yourself from maliciouscode but have little coverage of securing data transmissions etc...

I once had a similar problem with field headers printing while NO data was displayed despite data being present. This seemed to be caused by the number of boolean fields present. Replacing them with text fields solved the problem. Far from an ideal solution but it worked. If anyone knows...

I am writing an applet that must create a connection back to the server. However this seems to contravene java security rules as it throws a security exception when I create the Socket. What exactly must be done to avoid breaking the rules?

Add jdk to your path statement, then either reboot or run autoexec.bat in a dos window. If you are using dos, ie command line, compilation you may find you have to manually run your autoexec to set the PATH everytime you open a dos window. Batch files seem to work fine however.

I had the same problem but with a different control under VB5. Like you, I attempted reinstallations and I even tried manually editing the registry (dont do that!!!) I beleive that the problem is in the registry and no amount of reinstalling will fix it as Windows has now convinced itself that...

The errors seem to originate in CRYSTL32.OCX, product version 4.6.1.0, file version 4.6.3.7.14. This came with VB5. Is it possible to download a newer version of the file from somewhere? Would that help? The only call made to a crystal report control is crystalReport1.Action=1 to generate a...

I am developing a VB application that has problems.&nbsp;&nbsp;Half the time it is run it runs fine, the other half it brings up a &quot;out of stack space error&quot;.&nbsp;&nbsp;It also periodically throws up Illegal Operation orriginating in a DLL that is not my creation.<br><br>The...
