 | It looks like [Visual Studio has some flexibility, both in UI and custom actions](http://msdn.microsoft.com/en-us/library/vstudio/k2he6h0w(v=vs.100).aspx). I haven't used these myself, so I can't help with specifics, but that should get you started. There are also third-party options like [CPack](http://en.wikipedia.org/wiki/CPack) (produces [NSIS](http://nsis.sourceforge.net/Main_Page) projects on Windows).  |
| | Re: C++ Problem ...but we can help point you in the right direction. Have you written any code yet? If you have, please post it and try to identify a specific problem you're having. If not, here's a place to start: You'll need to read that data file into something. What kind of … |

| | > it could break certification because the checksum may be involved in the process when issue the certification This is one of the major reasons to have a certificate; to protect against modifications. Though the signature algorithm is usually much more secure than a simple checksum. > after I started … |
 | Having a control in a separate assembly reach into your main program directly to change values is not good design. A better approach is to have your custom button class have an [event](http://msdn.microsoft.com/en-us/library/aa645739%28v=vs.71%29.aspx) or [callback](http://msdn.microsoft.com/en-us/magazine/cc188909.aspx); your program can register something to happen when the button decides it's time. An event … |
| | > Is there a character, that can be written/read by system (C#/.NET), but can't be written by any standard keyboard Strings in .NET are Unicode, so you have plenty of options. Something like `'\xFFFD'` ("Replacement Character") might be the closest to what you're looking for. But that seems overkill; you're … |
 | Re: Allegro Game > there are few problems are occur so can any body help me What problems are you having? |
| | Loop through the row collection. With each row, look for the value you're trying to find. If you find it, use your iterator (maybe a `for` loop variable) to identify the row. If you're having trouble with a specific chunk of code, post it and we'll try to find out …  |
| | > `if ((s1[i]|32) < (s2[i]|32)) //Set the 6th bit in both, then compare` It's a case insensitive comparison. Have a look at [this ASCII table](http://web.cs.mun.ca/~michael/c/ascii-table.html). The difference between `'A'` and `'a'` is 32 = 2^6, and uppercase letters all have bit 6 clear. So if you set bit 6, you … |

| | Re: read from file If you're writing for a DOS-like environment, you'll have to use a few of the [interrupt 21h](http://spike.scu.edu.au/~barry/interrupts.html) functions. Start there, and if you have trouble, post code and we'll help you improve it. |

| | What have you tried so far? Do you have more specific instructions? What is supposed to go into the stacks? I would guess digits. You'll need to track some extra data, but you shouldn't need a whole third stack.  |
 | > Anyhow, what i dont get, is how to calculate this from the csv file. I hardly believe that what they want us to do is to simply create two variables... It sounds like it really is that simple. I read "calculate from the CSV file" to mean that you … |
 | Re: Postfix Notation Assuming you have somewhere to enter a postfix expression, use [the postfix algorithm](http://en.wikipedia.org/wiki/Reverse_Polish_notation#Postfix_algorithm) to evaluate it. Are you also looking for answers to your questions in `StackArray`? |
| | It looks like you're missing a `finally` before the block that closes the connection.  |

| | > This is mostly done with what is called a recursive descent parser See also the [shunting-yard algorithm](http://en.wikipedia.org/wiki/Shunting-yard_algorithm). |
| | Instead of recursion like you have for the depth-first search (`nadjiPut`), you need to keep a list of places to visit next. http://en.wikipedia.org/wiki/Breadth-first_search#Algorithm |
| | It looks like `rs.Open` is throwing an exception, but you're ignoring it. You should do something in that `Catch` block to report what went wrong. |
| | Your question seems a little confused about the role of exceptions in input validation. Do you have a specific example of what you're trying to do?  |
| | SQL Server's `bigint` type maps to `Int64` in .NET, so that's right. It looks like you're trying to assign the result of the conversion where it won't fit. What type is `this.bigInt`? |
| | If I were interviewing people, I'd be a lot more interested in ability than enthusiasm. Games are still software, and writing them can be much more demanding than typical business solutions. Do you have the impression that they're looking specifically for game lovers? Also, is this a general-purpose "software engineer" …  |
| | When I've seen this kind of error before, it's usually one of two things: 1. The ActiveX object wasn't [registered](http://support.microsoft.com/kb/249873) properly--or simply doesn't exist. 2. The application was built with reference to a version of the ActiveX object with a different class ID. I'd look at #1 first--which ActiveX components … |
 | You're probably looking for the [Image](http://msdn.microsoft.com/en-us/library/system.drawing.image(v=vs.110).aspx) class. Its [PixelFormat](http://msdn.microsoft.com/en-us/library/system.drawing.imaging.pixelformat(v=vs.110).aspx) property will tell you the pixel type. As for contrast... Do you mean the image's [dynamic range](http://en.wikipedia.org/wiki/Dynamic_range#Photography)? That's something you'll have to calculate yourself from the image contents. |
 | Code? In particular, your mouse event handlers, paint method, and anything you're using to track object position & orientation will be helpful. |

 | On which line is that error occurring?  |
 | You could write a function to loop over `array`, assigning the appropriate values to the right places. You could have a duplicate of `array` that you don't change during the game, then just copy it into `array` when you want to reset. My advice is that you don't mix the … |
| | Here are some thoughts that may help guide you: * Is the existing desktop application easily translatable to the Web? Some are, some aren't... if it isn't, that may be a point in favor of Xojo (about which I know nothing), if it can take the same application and publish … |

 | > I understand GA through pseudocode, but I don't know how to apply it in timetabling. This is the tricky part... if you model your problem well, GAs will do a pretty good job. Do you have a more specific problem statement? > And can I use PHP to develop … |
| | To start with, you'll need a good idea of what a solution to the scheduling problem might look like. Do you have more requirements than "develop a smart scheduling system" for this project? Once you know the basic "shape" of a solution, the important things to determine are 1. how … |
| | If you go with PHP, you can [perform XPath queries](http://php.net/manual/en/simplexmlelement.xpath.php) on your data. |
| | |
| | Also, at some point you should look into using [parameterized queries](http://msdn.microsoft.com/en-us/library/yy6y35y8.aspx). |

| | What is the type of `database_WICs`? Also, what line does the error indicate? |
| | MD5 and SHA-256 are [hash functions](http://en.wikipedia.org/wiki/Hash_function), not encryption algorithms. They only work one way, which is why you aren't finding anything else; that they are non-reversible is quite intentional. Is this for something specific you're trying to accomplish, or are you just exploring security concepts? |
| | Let's look at `reversed()` real quick here... if(!this.isEmpty()){ return this; } "If I'm not empty, just return myself"--probably not what you meant. Seems like it should be the other way around: "If I'm empty, return myself." But that's problematic too... it's a reference to the same object, which again I … |
| | [From MSDN on HttpRequest.Files](http://msdn.microsoft.com/en-us/library/system.web.httprequest.files.aspx): > Gets the collection of files uploaded by the client, in multipart MIME format.

| | Without details, I can't give you a specific answer, but this is where to fix your immediate problem: > FRS.Source = "SELECT * FROM Family" You could add a WHERE condition to this query to only count entries for a specific branch. This is a little fragile, though. You might … |
| | Re: c# db > UNABLE TU DELETE What does that mean? What happens when you execute the query? > " DELETE FROM Table1 WHERE Fname =" + textBox1.Text + "" Why are you appending an empty string to the end of the query? The append would make sense if you were surrounding the … |
| | Do you mean [like this](http://www.sitmo.com/article/generating-correlated-random-numbers/)? |
 | Just saying it "isn't working" isn't very helpful. Does the code not build? Does it build but not run? Does it run but produce unexpected output? Show us what you've been trying; please be specific.  |
