• .NET Development Large data transfer

  I created a local web service that accepts a byte array as a parameter and then I write the data in the array to a hardcoded file name. I added the following entry to the web service app's config file and my computer's machine.config files: < httpRuntime maxRequestLength = " 1048576 " executionTimeout = " 180 " /> I can successfully transfer 50 megs worth of data but it fails with the following error msg when i try to send a 100 megs of data (1 gig is my goal): {"The underlying connection was closed: An unexpected error occurred on a send."} System.Net.WebException: {"The underlyi ...Show All

• Visual Basic Standalone application

  Hi, I am looking to produce a standalone application supplied on a cd, which will be given to sales reps. They in turn will open this program from the cd or their computer. The program will have the facility to choose different powerpoint slides from different powerpoint presentations represented by thumbnails. Some of the powerpoint presentations contain numerous sections with numerous slides in each section, so it would be best if there was a button named “example” for the chosen powerpoint file called “example.ppt”. The button “example” would have a dropdown menu for the sections within “example.ppt,” this when clicked will provide a win ...Show All

• Visual C# How to update an Access Database (C#)

  Hello All, I am a little new to Visual Studio, but I hold 3 years programming experience in both Java and C. I have created a program for my wife that allows her to organize and save her DVD collection to an access table. The program works just fine except for the save part. I can run my application, insert, delete, and edit the contents of the database, but it will not save. To my knowledge I am only working through the dataset and the data never hits the database file itself. I just need a little help here because I am excited to get this application rolling. It is a little useless if you can't save data. I have an access database ...Show All

• Visual Studio Generate many files from one template?

  I have a DSL now taking shape, including generating code that executes properly, and I must say I am pleased with how quickly it has come together. Now I have a secondary goal to fill: producing static documentation from the diagram. I'd like to produce a set of HTML files (one for each instance of the primary classes in the DSL). I don't see how I can do that with the current structure, which allows me to generate exactly one file from each template. Do I need to create a new DirectiveProcessor or TextTransformation class Can you offer any pointers on how to create many files from one template Thanks, Brian. ...Show All

• Visual Studio Tools for Office Toolbar button on all mail items in Outlook 2003 using VSTO

  I'm new to VSTO and Outlook programming. I'm having difficulty creating a toolbar button that will appear on all mail items (both new mail and received mail.) When I use the code in the Outlook programming labs for VSTO, it seems like the button only appears on the first window I open, and not on any other window. Does anyone have a quick snippet of code that can show me how to do this Thanks, Ike Hello Ike, well when programming Outlook there are some pitfalls. Maybe you can look on my VSTO Sample "X4UTools" that deals with multiple Explorers and Inspectors and also when you use Wo ...Show All

• Visual C# deriving from System.ValueType?

  Should I derive my objects from System.ValueType I think this would be ok if my objects consist of just value types. If it doesn't, I'm not sure what will happen. Maybe the compiler make the choice for me Thanks Jason Sorry, I'm being stupid - the compiler won't let me derive from System.ValueType!! ...Show All

• Software Development for Windows Vista Vista 5270 ATI Driver

  I've just installed Vista 5270 from my MSDN subscription, and I've gotten all of the hardware to work except my display driver. I currently have an ATI Radeon X800 XT (AGP version).

• Windows Forms Update Data With EndEdit and Validate

  Friends, Two questions, hopefully both easily answered. First, here is a small piece of code I pulled from MSDN to add records to a data source from a form. this .Validate(); this .myBindingSource.EndEdit(); this .myTableAdapter.Update( this .fleetDataSet.myTable); First question is: What is the Validate() method supposed to do I can find nothing on this one. Second, what do I need the EndEdit method for The pathetic little description of this method in MSDN library says, "Applies pending changes to the underlying data source". Isn't this actually accomplished by the update() method in the third line My particular ...Show All
