Visual FoxPro MSGraph.Chart.8 control
I need to make charts. I started with MSChart Control and so far I've accomplished almost all I wanted except for one thing which totally eludes me. I need a simple line chart, not columns or a pie. I need to display a row of data like DJIA or similar indices with no additional vertical bars or other embelishments. The curve comes out nice but a lot of space on the chart is wasted because the curve is being plotted too high on the chart in vertical direction. I have tried to manipulate MSChart.Object . Plot . Axis ( VtChAxisIDY , 1 ). ValueScale . Minimum value but it is not responsive at all. I do not know why: perhaps other paramete ...Show All

Visual C++ Converting Project to Use msvcprt.lib instead of msvcirt.lib
I am attempting to convert a project to use msvcprt.lib rather than msvcirt.lib. When I run nmake on the .mak file I am getting an error 'unable to open msvcirt.lib'. I have removed all references to msvcirt.lib in the .mak file. The error is actually occuring at the linking stage, so it looks like the reference is inside an embedded library. As far as I know I have successfully rebuilt all libraries used by the application with msvcprt.lib in place of msvcirt.lib. I am probably picking up the reference to msvcirt.lib through an include file, which includes an include file, which .... Any ...Show All
.NET Development VS 2005 Time delay in calling subroutine (Office Interop)
Hi to the group, I wrote a program originally in VB.NET 2003 to retrieve some outlook items. The program runs just fine. I have recently converted it to VB.NET 2005 and here is the issue: Program loads and runs up to the point of calling a subroutine - 'GetSomeOutlookItems'. The program has thus far taken about 1/2 second or so. The subroutine is in its own module and imports Microsoft.Office.Interop. The program now takes about 6 to 8 seconds to actually get to this subroutine. Once the program gets there it takes about 1/2 second to finish loading all the data. Is there something I am overlooking or doing wrong Did VS2005 convert my progr ...Show All
Visual Basic How to tell when a user logs on to windows?
I am using VS 2003 to write a service in VB, this service will run in the background and has to run on a user account rather than the local system so cannot do any GUI stuff (as far as I know). I have written a second app in c# to handle the GUI side of things and I want to run it when the user logs in to windows. Does anyone know how I can tell when a user logs on - is there a registry key I can check every few seconds or is there a more elegant solution Thanks. The _most_ elegant that I can think of is simply to install a short cut to your application into the 'All Users ...Show All
