• Visual C++ How to write line feed in a text file so Notepad can show them correctly

  Hi, I am writing a text file using WriteFile: if (WriteFile(hDestFile, myString, TotalBufferSize, &dwWritten, NULL)) bSuccess = TRUE; and everything is OK except that myString has some "\n" inside, one for each different line in the text file. The problem is that the Notepad opens this file and does not show a new line for each of this "\n" character. It shows some weird blank rectangles instead as if it does not recognizes them. Other text editor like EditPlus does show the new lines correctly indeed. I am interested in Notepad anyway because my costumer does not want to install any additional text editor. He only wants to take a look to the files generated by my app in the Notepad. I've already made a s ...Show All

• SQL Server Evaluate as an expression

  I have just been brought in a project that is a huge mess....They have specked this project to allow for a user to create ad hoc calculated expressions using tags of data that are supplied by another system. This sort of looks like this ID | Formula | A | B | C | D | 1 A + B + C 1 2 3 4 2 C - D + A 1 2 4 2 3 D - A + 1 4 2 6 8 They want to then evaluate the formula expression using the corresponding column-row values to arrive at a value. As of right now I am a bit lost on how to do this, does anyone have any ideas Thanks! Josh Rogers Unfortunately they have 6 days now before release of the first phase and they are just now pulling me in as you said an oh **** last ditch maneu ...Show All

• Software Development for Windows Vista Show of Hands! Is WF by itself a viable approach to addressing a customer's workflow needs?

  Like many of us in the forum I am in the all too often unenviable position to influence my client's decisions. I currently have a lot of customers evaluating workflow, many for the 1st time. I personally have avoided building "custom" workflow solutions whenever possible as I have had success in the past implementing packaged workflow or BPM offerings, both Microsoft-based and less recently non-Microsoft-based. It's allowed me to focus my energies on building solutions and solving real business problems, not building infrastructure. Granted, there are customer situations that don't require or afford you the opportunity to buy a packaged solution to address a workflow/BPM need, but I would argue those are/should be the exception n ...Show All

• Smart Device Development I want a button that will navigate to the My Document folder when pressed

  I want to have Buttons in a VB Form navigating to places like,My Documents, Network Places, My Pictures etc. Does anone know code for me to be able to do this... Thanks That code could not possibly do that. At best it would print out some stuff to console if you have it or do exactly nothing if you don't have console (which is the case on most Windows Mobile devices). Depending on what do you mean by “take you to the folder” you should use something else, e.g. launch a file explorer process via System.Diagnostics. Process class or open file dialog using System.Windows.Forms. SaveFileDialog/OpenFileDialog. Just out of curiosity: how you come to the conclusion Console.WriteLine would “take ...Show All

• Visual Studio Cannot Reference COM Assemblies

  Hello, I have run into a problem when I attempt to reference the Office 2003 Interop assemblies (VS 2005). I am trying to reference the assemblies through an SSIS script component. When I right click 'References' in the Project Explorer for the script and select 'Add Reference', I don't have the COM tab from which to reference the assemblies. I only have the .NET tab. I can see that the 'Microsoft Office 2003 Primary Interop Assemblies' are installed when I check 'Add or Remove Programs' from the control panel. When I check my setup for 'Microsoft Office 2003 Professional Edition', I can see that I have '.NET Programmability Support' for all MS Office products.

• Visual C# How to have multiple sets of application settings?

  Hi, I'm using the standard mechanism to set and retrieve application settings (using app.config, Settings.settings and Settings.Designer.cs). I can set the application settings using the Visual Studio IDE and retrieve them like this: string title = Properties. Settings .Default.WindowTitle; This works fine - for a single set of settings. But now I'd like to run multiple instances of my application, pass them an argument that makes them unique (1, 2, 3, or "master", "slave"), and use that argument to access a specific set of settings. Preferable something like: string title = Properties. Settings .Master.WindowTitle; or string title = Properties. Settings["Master"] .WindowTitle; Is thi ...Show All

• Visual C++ Custom Dll with MFC linked

BUT the MFC library provides it's own DllMain.
