• Software Development for Windows Vista XPS Viewer - SDK & plug-in interface?

  Hi, is there a plug-in interface/SDK for the XPS viewer that allows third parties to extend the functionality of the XPS Viewer Regards, nixps The xps viewer will be the default application to render xps files on both Vista and XP (at least, that is how I understand it, please correct me if I'm wrong). I'm interested in extending the functionality of that particular application: so that users can use their familiar xps viewer, but with extra functionality that is provided via a plug-in (provided the plug-in is installed, of course). My question: is this, or will this be, possible nixps ...Show All

• Visual Basic [OTP]Place Points in audio.video files

  My multimedia teacher has asked us to find a term that means "to place points in the audio/video file" this term has the same number of letters as the word "redact"   nobugz wrote: On the other hand, they might be elated about a "not business as usual" kinda question like this... You've got to be kidding me.   Look at the other threads that get marked/locked and tell me how this one differs...  facinating or not, this isn't the right place for it. Even if you don't lock it, at the very least it must be marked OTP...  This has absolutely nothing to do with VB or programing and will just end up as more garbage for people searching for legit help in coding around AV files to wade through. -EDI ...Show All

• Windows Forms Is There No Event That Fires When User Tabs Out After Changing Text

  Most languages--e.g. Powerbuilder, MS Access, Java, Javascript--provide an event that fires after the user tabs away from an input control such as a textbox, but only if the text was changed.  I can't find such an event in .Net.  "Validating" fires after focus leaves the control, but fires whether a change was made or not.  You would certainly want to avoid a resource intensive edit, such as one involving a database hit, if the text was not changed. Is there really no such event in .Net    (VS 2005, programming in VB.Net.) Hi, Based on my research, it seems that .NET textbox did not provide such an event. Also how did you define the behavior of the ...Show All

• Software Development for Windows Vista How to record from 'Wave' or 'Stereo Mix' in Vista?

  Hi all, I wrote the following question in other forum space but some MSFT guy told me to try this forum for my question. I hope I could get right answer as soon as possible here. On Windows XP or earlier, I could capture the audio stream to the speacker not from the external device (maybe endpoint device in Vista) like the microphone. In other words, D irectSoundCapture was able to capture from the selected recording device/source line in the Windows record control utility or mixerXXX APIs. And if "Wave Out Mix" or "Stereo Mix" or something similar was selected as recording source line, D irectSoundCapture was able to record the audio stream to the speacker. However, I could not find the way to do tha ...Show All

• Visual C++ Class / Member Class relationship

  Hi Guys, I have a question. Here goes: class clsManager { public: int x; int y; } class clsContainer { public: int a; int b; clsManager oManager; } So I have these two classes, first class is a member of second class. Is it possible to to access members of class clsContainer from the object oManager How can it be done Thanks & Best Regards. Faisal. Great.  I forgot to add: Furthermore, I would add a member in clsContainer that creates instances of clsManager with new clsManager( this ). Also, the oManager member seems out of place.  Wouldn't you instead have an array of them   (std::vector<clsManager*> perhaps ) ...Show All

• Windows Forms DataGridView RowValidating doesn't show the ErrorText icon

  Hi all.... I have a databound DataGridView control. I have implemented RowValidating event because I need to verify that certain cell of the row being validated has a correct value.

• Visual Studio Tools for Office VSTO and MS Office licensing requirements : Developer vs End User

  I keep seeing conflicting, if not confusing, information about the system requirements for end users vis a vis the versions of MS Office that can run VSTO solutions for Outlook 2003. The page that most folks refererence states that developing and running Office customizations built with VSTO requires MS Office 2003 Professional Edition or MS Outlook 2003 (stand-alone). In addition, the Office web site also states that solutions built using VSTO will not work unless you are using Office Professional Edition 2003. I can understand the requirement for the professional edition for developers but is it really true that end users also have to be using the professional edition also Can someone please confirm this important issue and if true, ...Show All

• Visual C++ Inactive Process slows down in XP.

  I have an observation to share and would like if someone can come up with explanation and any way around to fix it. Actually I have an application running on XP that retrieves data from db and displays a graphical representation of this data. This operation is performed on request and this application is a small part of a large system having other processes more agressively running. So it is a very common case that this application's process remain idle for long time and then on request performs its operation and goes back to its inactive state. Initially when I start the system and plot the data trend it work pretty efficiently, but when I perform the same operation (same amount of data with same trend configuration) after for exampl ...Show All

• Visual Basic Proper way to refresh a form

  I have a program that process big databases, and meanwhile, displays some status output. All goes inside the typical While Not srInput.EndOfStream When i was working with visual 6, a me.refresh inside this loop would update all the form info, but, if i try to do so now, the app gets really slow, so i have to find another way..... what i do now is to refresh every 100 lines are processed, but i still dont like it... Does anybody know how to refresh the form in a proper way Thanks I would put the doevents in a timer event rather than a certain number of iterations.   This way you can ensure that the UI is updated during these looping processes - even x number of milliseconds.  &nb ...Show All

• .NET Development prorgamFilesPath

  I'm a bit new to C# So here my problem. I am developing on XP-64bit, there is a 'Program Files' folder and 'Program Files (x86)'. The problem: I had developed this program with a Button on a 32-bit version so it automatically points to 'Program Files' but now that I'm on 64-bit version the program that the Button executes is in 'Program Files (x86)'. Is there any way for the button to search both 'Program Files' folders You could use environment variables to find the folders. A 32-bit process running in 64-bit Windows has its "Program Files" environment variable point to the C:\Program Files (x86) folder and the "ProgramW6432" variable point to the C:\Program Files folder. ...Show All
