• Good HTML/CSS/PHP editor that is free and multi-platform?

  - by Earlz

  Hello, I have recently given up on using Visual Studio for Windows editing. See, PHP isn't really important as I have hardly any pages that use it, but in VS, if it smells PHP then it won't treat it as HTML and thus will all be plainly formatted.. so.. I'm looking for some sorta HTML/CSS/PHP editor that is free and multi-platform(so I can also use it at my home OpenBSD computer) And please don't suggest emacs or vi. I'm learning more and more of nvi, but I'm looking for a graphical editor right now. Can anyone suggest a good editor for my needs?

• Imitate database in C

  - by Mohit Deshpande

  I am fairly new to C. (I have good knowledge of C# [Visual Studio] and Java [Eclipse]) I want to make a program that stores information. My first instinct was to use a database like SQL Server. But I don't think that it is compatible with C. So now I have two options: Create a struct (also typedef) containing the data types. Find a way to integrate SQLite through a C header file Which option do you think is best? Or do you have another option? I am kind of leaning toward making a struct with a typedef, but could be pursuaded to change my mind.

• Knowledge for writing a compiler for Win32

  - by saf

  I have created an interpreter for my programming language (educational) and now I'd like to go one step further and create a compiler for it. I know that this is pretty hard work. What I already know is: I need to translate my input language to assembler A lot, isn't it? Now what I don't know is: What assembler do I need to create Win32 PE executables like, for example, Visual Studio does? What about file headers? I'd prefer not to use MASM but it seems like I'll have to. How to combine the assembler with my compiler?

• What's the best way to handle web.config file versions in ASP.Net?

  - by MusiGenesis

  I have an ASP.Net web site (ASPX and ASMX pages) with a single web.config file. We have a development version and a production version. Over time, the web.config files for development and production have diverged substantially. What is the best practice for keeping both versions of web.config in source control (we use Tortoise SVN but I don't think that matters)? It seems like I could add the production web.config file with a name like "web.config.prod", and then when we turnover all the files we would just add the step of deleting the existing web.config and renaming web.config.prod to web.config. This seems hackish, although I'm sure it would work. Is there not some mechanism for dealing with this built in to Visual Studio? It seems like this would be a common issue, but I haven't found any questions (with answers) about this.

Thanks

• Purpose of Trigraph sequences in C++?

  - by Kirill V. Lyadvinsky

  According to C++'03 Standard 2.3/1: Before any other processing takes place, each occurrence of one of the following sequences of three characters (“trigraph sequences”) is replaced by the single character indicated in Table 1. ---------------------------------------------------------------------------- | trigraph | replacement | trigraph | replacement | trigraph | replacement | ---------------------------------------------------------------------------- | ??= | # | ??( | [ | ??< | { | | ??/ | \ | ??) | ] | ??> | } | | ??’ | ˆ | ??! | | | ??- | ˜ | ---------------------------------------------------------------------------- In real life that means that code printf( "What??!\n" ); will result in printing What| because ??! is a trigraph sequence that is replaced with the | character. My question is what purpose of using trigraphs? Is there any practical advantage of using trigraphs? UPD: In answers was mentioned that some European keyboards don't have all the punctuation characters, so non-US programmers have to use trigraphs in everyday life? UPD2: Visual Studio 2010 has trigraph support turned off by default.

• Is WPF a good choice for developing line of business user interfaces?

  - by Randy Minder

  We're debating whether our future Windows UI development should be WinForms or WPF. How have some of you made this decision? Most of our applications are LOB applications, and I'm not sure I see a clear and overwhelming benefit to WPF for these types of applications. However, my knowledge of WPF is limited. I'm also a little concerned that WPF will be in vogue for another couple years and then Microsoft will get tired of it and push something else on us. I guess one argument against this is the fact that Visual Studio 2010 is a WPF application. Thanks.

• Which is better for quickly developing small utilities? AutoIt or AutoHotKey?

  - by Abhijeet Pathak

  Which is better for quickly developing small utilities? AutoIt or AutoHotKey or something else? I need to develop some small software for which I think using some professional suite like Visual Studio will be overkill. Most of the macro recording tools like AutoIt or AutoHotKey provide enough power to write decent application. Plus they are small and free. Which option will be good? Using one of these tools or using some other small/free compiler?

• Tutorials/Books on using Mono to develop RESTful webservices?

  - by max

  Hi, anyone out there got any pointers to good links/tutorials/books on developing webservices with Mono? In more detail, I am interested in using Mono from project start on a Linux host developing in C# using Visual Studio for development, ideally with remote debugging if that is realistic developing web-services in MONO accessible in a RESTful manner, returning JSON hiding the services processes behind an Apache access the services either via javascript/AJAX or from a thin script layer written in PHP scalability is important for me unit-testing of webservices Any recommendations for material I could sift through to get a good head-start? I might add that I'm C#/.NET savvy, but not in the context of web development. I've been using it since it came out, but mainly for internal server-client applications where the clients were Windows desktop apps and the communication layer was remoting or, sometimes, more low-level socket-based. Thanks, max

• Is there any way to code breakpoints/debugging?

  - by froadie

  I've been wondering this for a while - is there a way to code/program breakpoints...? Conditionally? For example, can I specify something like - "when this variable becomes this value, break and open the debugger"? (Would be quite useful, especially in long loops when you want to debug loop execution of a late loop value.) I suppose this may be IDE-specific since debugging is implemented differently in different IDEs... I'd be interested to know how to do this in any IDE, but specifically in Eclipse and Visual Studio.

• const TypedeffedIntPointer not equal to const int *

  - by dirk

  I have the following C++ code: typedef int* IntPtr; const int* cip = new int; const IntPtr ctip4 = cip; I compile this with Visual Studio 2008 and get the following error: error C2440: 'initializing' : cannot convert from 'const int *' to 'const IntPtr' Clearly my understanding of typedefs is not what is should be. The reason I'm asking, I'm storing a pointer type in a STL map. I have a function that returns a const pointer which I would like to use to search in the map (using map::find(const key_type&). Since const MyType* and const map<MyType*, somedata>::key_type is incompatible, I'm having problems. Regards Dirk

• Related objects in reportingviewer 10.0.0.0 give #error

  - by Bart-Jan Poirot

  In my VB.net apps i make use of Linq2SQL and Reportviewer with RDLC reports. With Visual Studio 2010 they upgraded this reportviewer component so you can use the newer RDL specification from 2008. Now I've a problem to show related objects. For example assume you provide an order to the datasource of the report and then you can show something like Fields!Customer.Value.Name where Customer is a related entity. I also got the error in my immediate window: *Warning: The Value expression for the textrun ‘Name_1.Paragraphs[0].TextRuns[0]’ contains an error: The specified operation is not valid.

• How to start a Process as administrator mode in C#

  - by RP

  I have a visual studio windows app project. I've added code to download an installer update file. The installer after it has finished downloading would need administrator privilages to run. I have added a manifest file. When user clicks on the DownloadUpdate.exe, UAC prompts the user for Admin permissions. So i assumed that all processes created and called within DownloadUpdate.exe will run in admin capacity. So i made the setup call my downloaded file with the following code: Process p = new Process(); p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; p.StartInfo.FileName = strFile; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.RedirectStandardError = true;

• Console output window in DLL

  - by user303907

  Hello, I am trying to redirect the output from my DLL to an external console window for easy debugging. I have been told about AllocConsole but I am not able to reproduce it, i.e. the console window does not appear. My current environment is Visual Studio 2005. I tried the following example which is gotten off the Internet, AllocConsole(); HANDLE han = GetStdHandle(STD_OUTPUT_HANDLE); WriteConsole(han,"hello",6,new DWORD,0); yet nothing happens. Can someone point me in the right direction if creating a console window via DLL is possible in the first place. Thanks in advance!

• C# and Linq: Generating SQL Backup/Restore From Code

  - by mdvaldosta

  I'm working with a C# and Linq to SQL Winforms app and needed to integrate backup and restores through the program. I used SMO and got it working pretty smoothly. The issue, however, is that the app is deployed using ClickOnce, which I like very much - but since I had to include the dll's the download size jumped from 3mb = 15mb. I know they've only got to download it once, but it also sucks for me as Visual Studio 2010 seems to upload the dll's every time and that takes a while on AT&T broadband (eh). So, anyone have any suggestion on how I can work out an effective backup/restore solution without using SMO objects?

• [wxWidgets] How to store wxImage into database, using C++?

  - by Thomas Matthews

  I have some wxImages and I would like to store them into a BLOB (Binary Large OBject) field in a MySQL database. There are no methods in wxImage nor wxBitmap for obtaining the binary data as an array of unsigned char so I can load into the database. My current workaround is to write the image to a temporary file, then load the BLOB field directly from the file. Is there a more efficient method to load and store a wxImage object into a MySQL BLOB field? I am using MySql C++ connector 1.05, MS Visual Studio 2008, wxWidgets and C++.

• How to have a dynamic theme color in WPF

  - by Ingó Vals

  In WPF I have a few resource dictionaries and in them styles for my panels and controls in my app. I'm reusing the same colors again and again. I actually have 5 colors and they give my app a good color-scheme. However if I wan't to change the theme I have to go into the RD's and change each and every color there. I would like to somewhere have the colors set but don't know how or where. I tried to put a color tag in one RD but as soon as I referenced it in the same RD Visual Studio crashed. Also the best solution would be that I could have the color as a dynamic setting in the app itself so users could even change it themselves.

• Using Thrift to connect to Cassandra from .NET

  - by vtortola

  Hi, I'm interested in Cassandra and I'd like to test it at home in my Windows XP computer. I've found instructions for install an run Cassandra in Windows, and it's already up and running; I've also found the thrift executable for Windows and generate the C# interfaces, but... when I try to compile that generated code in Visual Studio I got : "The type or namespace name 'Thrift' could not be found (are you missing a using directive or an assembly reference?)", so I'm missing something else, but I cannot find what... What is it? Is it a dll? I've looked in the thrift code and I cannot find anything related to .net , so what am I missing? Thanks in advance. Regards.

• SQL Server 2008 - Script Data as Insert Statements from SSIS Package

  - by Brandon King

  SQL Server 2008 provides the ability to script data as Insert statements using the Generate Scripts option in Management Studio. Is it possible to access the same functionality from within a SSIS package? Here's what I'm trying to accomplish... I have a scheduled job that nightly scripts out all the schema and data for a SQL Server 2008 database and then uses the script to create a "mirror copy" SQLCE 3.5 database. I've been using Narayana Vyas Kondreddi's sp_generate_inserts stored procedure to accomplish this, but it has problems with some datatypes and greater-than-4K columns (holdovers from SQL Server 2000 days). The Script Data function looks like it could solve my problems, if only I could automate it. Any suggestions?

• Making "helper" windows in WPF

  - by RandomEngy

  I'm writing an app in WPF and want to make a "helper" window. The window needs to be resizable, with no minimize option and doesn't show in the taskbar. If the app receives focus, it should appear as well, but whether or not it's in front or behind the main window should be retained. When the main window is closed, it should close along with the app. An example is a detached pane in Visual Studio. I've made the helper windows not appear in the taskbar, but can't get the rest of the behaviors I want. If they're their own windows, they don't get focus along with the rest of the app. If I specify a the main window as their owner, the main window can't be on top of the helper window. Anyone know a good way to approach this?

• C# going nuts when I declare variables with the same name as the ones in a lambda

  - by Rubys

  I have the following code (generates a quadratic function given the a, b, and c) Func<double, double, double, Func<double, double>> funcGenerator = (a, b, c) => f => f * f * a + b * f + c; Up until now, lovely. But then, if i try to declare a variable named a, b, c or f, visual studio pops a "A local variable named 'f' could not be declared at this scope because it would give a different meaning to 'f' which is used in a child scope." Basically, this fails, and I have no idea why, because a child scope doesn't even make any sense. Func funcGenerator = (a, b, c) = f = f * f * a + b * f + c; var f = 3; // Fails var d = 3; // Fine What's going on here?

• Clipboard Debugging

  - by Jake Pearson

  In the olden times of .NET 1.1, I could use the SoapFormatter to find out exactly what was getting serialized when I copied an object into the clipboard. Fast forward to 2010, and I tried to do the same trick. It turns out the SoapFormatter does not support generics. Is there an alternative way to find out exactly what binary objects are serialized into the clipboard? For example lets say I have this class: public class Foo { public List<Goo> Children; } If I send an instance of it to the clipboard, I would like to take a look at what is in the clipboard to see if it's children list was included or not. Update: I was finally able to find the over copied field with the debugger. Visual Studio did it's job.

• Size and position of the C# form.

  - by Vytas999

  I use Visual Studio .NET to create a Windows-based application. The application includes a form named CForm. CForm contains 15 controls that enable users to set basic configuration options for the application. I design these controls to dynamically adjust when users resize CForm. The controls automatically update their size and position on the form as the form is resized. The initial size of the form should be 650 x 700 pixels. If CForm is resized to be smaller then 500 x 600 pixels, the controls will not be displayed correctly. How I must ensure that users cannot resize CForm to be smaller than 500 x 600 pixels..?

• F#: how to find Cartesian power

  - by Nike

  I have a problem with writing a Cartesian power function. I found many examples about calculating Cartesian Product, but no one about Cartesian power. For example, [1;2] raised to power 3 = [ [1;1;1] ; [1;1;2] ; [1;2;1] ; [1;2;2] ; [2;1;1] ; [2;1;2] ; [2;2;1]; [2;2;2] ] I use following code to calculate Cartesian Product: let Cprod U V = let mutable res = [] for u in U do for v in V do res <- res @ [[u;v]] res And trying to calculate Cartesian power. I use following code to calculate Cartesian Product: let Cpower U n = let mutable V = U for i=0 to n-1 do V <- Dprod U V V Visual Studio said: Error The resulting type would be infinite when unifying ''a' and ''a list'. I will thankful for any help and links.
