• Tomas Galvez WinINet.dll dependency

  I have created a setup project using VS .Net 2003 for one of my MFC applications. I am using WinInet API in that application and hence the setup project automatically picked up WinInet.dll as a dependency. But I am not sure if I really need to package it in the MSI. Can I safely exclude WinInet.dll and assume that it will be available in the target machines This will reduce the size of the build by 600K. I am targeting only XP and 2000 machines. If it can be excluded, what precautions need to be taken during installation Any help would be appreciated. Thanks Thanks Phil. I will take that as a "yes, you can safely exclude wininet.dll from the setup project". Thanks again. It's been part of the OS since Windows 2000, ...Show All

• Blkbird Datagridview unbound computed on bound...which event to use?

  Okay, I've spent the day trying to get this right, and not quite there yet. So much for rapid application development. Please advise My datagridview control has bound columns and unbound columns. I want the unbound columns values set based on a computation against the bound columns. Say my boundcolumn value is a date Sep 20 2006, so I want my unboundcolumn value to be assigned "Wednesday". I can do that fine in various events, but not immediately after the initial databinding...my unboundcolumns are remaining blank until my user starts selecting cells because I haven't solved which event when the datagridview is first loaded to use to calculate the unboundcolumns. Any ideas I've tried after the rowsadded and databindco ...Show All

• grumbs FillByParameter - using parameters with the Select Statement

  Hi, I want to open a new form (form2) and have it load only the data for an item chosen from a datagridview in form1. In the constructor, I'm passing the ID of the record chosen to the constructor of the form2 in the field mID. Form2's data is in a master-detail relationship. So I have created a dataset, dsSermons21, that contains the 4 other child tables. In dsSermons21, I have created a new parameterized Select query call FillBySermonID. Now, If I understand this correctly, I use the following to fill the Sermons table of the dataset: DsSermons21.Sermons.FindBySermonID(mID) I do not know where it got FindBySermonID from, then name of the new query is FillBySermonID, but that is what came up in intellisense.

  I have a non-visual class like (avalible in the toolbox) public class MyClass: Component { public MyClass() {...} } In this class I have some asyncronus external events that needs to be syncronized with the "main - gui - thread" that consumes events from "MyClass"...

• EtherealSky How do I detect if one of the combobox has value in a panel grouped with 8 combobox?

  Hi Please somebody help. I am using vb.net or vb 2005 I have 8 combobox in a panel (Panel1) and have textbox1 outside of the panel1. If textbox1 is 2 or 3, one of the combobox in the panel1 must be completed.

• troy2 How to hide form from Alt-Tab dialog

  Hi, I'm creating a borderless form by setting this.FormBorderStyle = FormBorderStyle.None When I show the form, if users press Alt-Tab to switch among applications, they can still see it. How can I disable it Thanks a lot. Do I dare ask a) why and b) what FormBorderStyle has to do whether the application shows up in the Alt tab window The property ShowInTaskbar  would have a greater possibility of controlling whether the application shows inthe Alt-Tab menu long before a borderstyle does. I believe The reason that it shows in the taskbar is because of a trick that .NET uses to do the SysTray. I've noticed that if you set the show in taskbar to false and set the ...Show All
