• Visual Studio Express Editions Can I replace 7 chars with 5 chars at the beginning of a string?

  #include <string> using std::string; s.replace(0,5,"12345"); // replace the 1st 5 characters s.erase(5,2); //then delete the superfluous 2 or is there a better way Not really in this case, as standard string just moves the "begin" pointer to the start of the valid data, it only reallocates memory if there is not enough space in the string. ...Show All

• Windows Forms Getting a value from a control at another form

  Hi My problem: lets suppose that we have a form called Form1 and has a textbox control called textBox1 and another form called Form2 that has a label control called Label1 and I want to set the content of Label1 with the same content of the textBox1 in Form1 what is the suitable code for such a purpose. Thanks Hi Ranadheer, in the previous code example there is a property called UserEnteredValue which returned the string entered by the user in the textbox. In your case you will create a property which will return the listbox's SelectedObjectCollection i.e. public SelectedObjectCollection UserSelectedItems { get { return this.myListBox.SelectedItems; } } ...Show All

• .NET Development Web Service Invoking via HTTP POST

  I have a web service and it works correctly and I can invoke its only function via the asm test page that uses HTTP POST. I want to be able to call the service via a the wininet library that uses a call to a web page. I have the following link to my web service and It doesn't seem to work like this. I would think it would because this too should be a POST right Link -> http://localhost/SubmitOrderService/SubmitOrderService.asmx/SubmitOrder param1=10&param2=0 However, I get the following error when I put a link like this in a browser and call it; Server Error in '/SubmitOrderService' Application.

• Visual Studio Express Editions Internet Time Update

  The internal clock of my PC is very slow. I need very high precission time in my PC while I am running some time sensitive VBE applications. Can the PC time, the one that Now gives out, be updated with an Internet Timer Server, through VBE I know how to do this manually by going in to Date and Time Properties. I need it programmatically. I guess it is just a matter of knowing the protocol these Time servers use.

• Game Technologies: DirectX, XNA, XACT, etc. .xnb file size

  Hi all, I assume I am doing something wrong with the importing of content, but I can't seem to figure this out. I have 3 .bmp images that are each around 30kb. I am importing them as Textures and using the Sprite processor. The resultant .xnb files are 250-300 kb =/ I am fairly sure the .xnb file doesn't have mipmap data in it. Any idea why these images are becoming so large Thanks Leaf. wrote: You're just telling them what button to press, I'm trying to educate here.

• SQL Server Losing record after synchronizing subscriptions

  Hi We got a server running SQL server 2000 SP4 with a database that’s being replicated There are 17 subscribers running MSDE SP4 using merge replication. Replication is started manualy Initially we tested this with two subscriptions an everything went well, but now, since 3 months, we are facing a weird problem while sync'ing. We have massive data loss on records that where inserted at the subscribers. Records seem to disappear, but only record that have a foreign key constraint. What I mean is that for example a record is inserted at the table that holds our client records with primary key ‘ClientID’ and then a record is inserted in a table with actions for that client with a foreign key ‘ClientID’ referr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Landscape Content

  A game like Halo has large man-made structures and organic landscapes. How is this content generated Do they use commerical prorams or does each game company have proprietary programs How is this content saved In standard files like X files, or does each company use proprietary formats Thanks... Up Front: XNA GSE currently will not load 3D content, but should next spring, so this is about the future. Thanks for the link to 3D Content programs. I am confident that the bulk of XNA GSE can not come up with $3500 for 3DSMax, so what can we use for Landscapes I have 3D Canvas Pro, which works vwey well for 3D objects, but seems useless for Landscapes.
