• Visual C# how to make form invisible on startup?

  I have an application that minimises to system tray and runs on windows startup. I would like the application to start with the main form invisible when loaded. Everything I've tried so far has failed. Any ideas Yes, that seems to work quite well now. Here's my solution for future reference: I have a boolean stayHidden which gets initialized when the form is created depending on wheather or not the program was started with a command line argument or not. Then in the VisibleChanged event of the formI have: if(stayHidden) this.Visible = false; This sets the form invisible when it loads. I made the applic ...Show All

• Software Development for Windows Vista Workflow Designer Rules Support

  Hi, I'm in the process of trying to setup a demonstration application which shows an example of workflow and rules management. I need to basically setup a workflow, set some properties, then run the workflow from the designer. Part of this demo include the use of an IfElse activity and a Policy activity which link with the rules engine portions. I've trundled through the examples and the current samples get things about 75% of the way there, and I've probably gotten another 5-10% there by looking at the threads here, but I'm still stuck. Here is what's happening: 1. Create a new workflow 2. Drop an IfElseActivity on the design surface, thro ...Show All

• SQL Server Help, please ...

  I have a backup of a SQL Server 2000 database that was created in a production environment. I don't have access to that environment at the moment and so I downloaded SQL Express in hopes of being able to restore, open and explore that database backup on my desktop. Question: Does SQL Express have a desktop client analogous to the one that comes with SQL Server Enterprise Manager If yes, how does one activate it If not, what do relatively non-technical people -- as I would characterize myself -- typically use with SQL Express to "get at" their data Thanks very much for whatever assistance is offered. ...Show All

• .NET Development Null Value exception thrown, need to change default action

  Migrating a legacy Access VB6 app to VS 2005 B2, the old app handles null's read from ADO recordsets in its own way. The migrated code using a dataset is suffering from exceptions that the generated dataset code throws. I need to be able to reset the default action to either ignore or replace etc. This is an option for the field in the dataset (codegen etc). However I would like to do it once for the entire dataset (30+ tables of 20 columns and n assorted queries etc). Doing this by hand for each field is a real pain. Is there a way to change the default null handling option from throw exception to anything else, when initially gen ...Show All

• Visual C++ std::map<,>, xtree and find

  I am working on an unmannaged C++ application in Visual Studio 2003.  The application is using STL map class. std::map<ApxString, CGPO> GPOs; GPODataFactory.GetGPOs( pContext,  GPOs); std::map<ApxString, CGPO>::iterator GPODataIter = GPOs.find( GPOGroupKey)   GPOGroupKey is of type ApxString of course and it was initialized to "T" earlier in the program. When I go through the debbuger in the GetGPOs function and use the find function, I find the row I am looking for.  However, when I go through the find function after I exit the GetGPOs function, I don't find it. As I stepped into the find function, ...Show All

• SQL Server Running SQL Server on a Desktop Machine

  Hi, The company I work at was going to install SQL Server 2005 on a server running Windows Server 2000. However this server is no longer available, and due to cost restraints we are unable to purchase another server. I still wish to get SQL Server 2005 running, and have a spare desktop computer avaible. This computer is a P4 3.2GHz with 1GB of RAM and 40GB hard disk. I was thinking of adding RAM and a larger hard disk, and installing Windows Server 2003 on it. Is it advisable to run SQL Server 2005 (and Server 2003) on a desktop computer Any comments or experiences of similar situations would be appreciated. Thanks, Matt ...Show All

• .NET Development Deserializing Delegates/RuntimeMethodInfo

  I wrote a custom formatter that serializes events. Serializing events results in a RuntimeMethodInfo class being written out to the stream. RuntimeMethodInfo does not have an appropriate constructor for deserialization so ObjectManager.DoFixups() fails with an exception. How do you deserialize events Thanks, Ray I missed IObjectReference somewhere along the line while writing the formatter or perhaps thought that it was taken care of by the object manager. - Ray ...Show All

• Windows Forms send values to a textbox from a textbox on other winform

  hi all, pls help me with this prob: i hv this one textbox on a form with some values (comma separated) and need to pass these values to another textbox on another form. Codes in C# are most welcome. VB.Net also fine. Thanks guys. Regards. Hi, first of all your two Forms do need to know each other .
