• Visual Basic tables

  Hi there Until recently I used RapidQ basic to produce my number crunching applications. The move to VB2005 was dead easy. There is however one feature / keyword I badly miss. In rapidq there is the StringGrid control, where you can print, for example, the values from an array on a GUI. Once you set-up the stringgrid, writing into it is a simple as: stringgrid.cell(xy) = str$(value) By comparison, generating a table in VB2005 is very difficult. Any suggestions will be appreciated. If it's still about that vanishingpointgame problem, then I don't know if this helps, but I think the lack of an WM_IME_NOTIFY message (=642) seems to be causing it. ...Show All

• Windows Forms MDAC 2.7 Prerequisite

  I need at least MDAC 2.7. I'd love to make MDAC 2.8 a Prerequisite, but I can't because MDAC 2.8 doesn't install on Windows XP SP1. You're required to load SP2, an onerous requirement we do not want to impose on our users. I'd like to add MDAC 2.7 as a Prerequisite, but I don't see a place to do so. Is there a way to add MDAC 2.7 as a Prerequisite in VS 2005 ...Show All

• Windows Live Developer Forums Right-Click Select and Zoom

  Has anyone managed to get this functionality to work. I want to have the ability to Right-Click and Hold anywhere on the map select an area and them zoom into it. I know there is the alt+click and the middle-click but a lot of your average users don't think of these methods. Most will try to use the method I'm trying to work out. I got a good part of it worked out, but I need to figure out how to override the click event on the VEMap Object, or how to get from the View returned the event I'm working with. So I can test for right-click on the onMouseDown event. Any ideas I had tried that. The problem is that the onContextMenu function is fired after the map pans. So you can't get a starting point only an en ...Show All

• Visual Studio 2008 (Pre-release) Why can I not see the wsdl file?

  Hello friends. Well, when I self-host services and enable mex of course, I can see the wsdl file. However when I host it on IIS7, even the most basic sample, I can host it and I can use svcutil to download metadata and everything, but when I click on the URL for the wsdl file, the page gives me error and I can't get to wsdl file.

• Software Development for Windows Vista UAC settings for DLL

  Windows Vista Readiness Hands on Lab has details on how to set UAC for an app, by accessing it's manifest settings from Visual studio: XML settings like the: "<requestedExecutionLevel level="Setting" /> . Applications that were not developed for Vista would have a Setting of asInvoker and since by default even if logged in as administrator applications are given reduced admin privileges, one need to explicitly promote this Setting to highestAvailable". My question is: say my application needs admin privilege, e.g. to set registry values, though the actual .exe source code are merely invoking a DLL (e.g. using LoadLibrary call), which does the bulk of the processing including the registry settings; do ...Show All

• Visual Studio 2008 (Pre-release) Quick NetMsmqBinding question

  Hi guys, I have a quick question about the NetMsmqBinding. I knew the answer to this at one point but managed to forget and now I'm having trouble finding the answer again. For the NetMsmqBinding, the queue needs to be on the Service-side right Can you use a queue on the Client-side or on a third machine Thanks, Ting Journal queues is actually a different feature. When the journaling is turned on, the copies of the messages are being stored in the special, journal queues, so they become available for inspection later. To reliably transfer messages to the destination queue, even if the destination machine is down, MSMQ uses the outgoing queues. These are created implicitly by MSMQ on the sender's machine. ...Show All

• Windows Forms SignTool reported an error 'XmlResolver can be set only by fully trusted code.

  Hi all, Everytime i publish my winform app, I encounter this error. "SignTool reported an error 'XmlResolver can be set only by fully trusted code." How can I fix this problem. Thanks I had this problem on my work PC, but not my laptop. After installing the VS2005 SP1 the problem did not go away. Then I had a look at VS Add-in Manager. I had XSDObjectGen in the list but it was not loaded. As a last desperate attempt I uninstalled XSDObjectGen and I finally had SUCCESS. So just having XSDObjectGen installed on your machine can cause the dreaded XmlResolver error during ClickOnce publishing. I hope that helps. ...Show All
