    - How to display My Network Places with FolderBrowserDialog I am using the FolderBrowserDialog in my application and it works well. However, when it is displayed, it does not include "+ My Network Places" in the list of available locations. I notice that other Microsoft applications (like opening a .zip file and clicking browse) do include My Network Places. How is this done? Thanks!

    - MDI, maximize child window Hi I have a windows form which has the following: form1.IsMDIContainer = true and panel1.Dock = DockStyle.Right. Then I create a new child window and set its FormBorderStyle = FormBorderStyle.None and WindowState = FormWindowState.Maximized. But what happens is the right half of this child window is covered by the panel and it's still showing the header of the window (icon, name, min, max, and close buttons) My questions 1. How do I make the child window maximize only on the left half on the parent window (not to make it behind the panel) 2. How do I hide the header of the child window when it's maximized Please advice, thanks -CL Tag: Crystal Reports Problem: Please reply ASAP Tag: 65339

    - control binding problem (MS, please respond) I've run into a problem with binding form properties to data in an xml file (through a dataset). As it turns out, I can easily bind if the data type of the property on the control is a normal datatype such as a string or integer. If the datatype is not one of the built-in types however, things go horribly wrong. Consider this xml file: <?xml version="1.0" standalone="yes"?> <SettingsData> <one> <Text>Center</Text> </one> </SettingsData> If I create a normal winforms application and add the following code to the form's constructor, it works. I get "Center" in the text box. Here's the code that works: DataSet dataset; dataset = new DataSet(); dataset.ReadXml(@"d:\development\bindtest\form.xml"); TextBox textbox = new TextBox(); Binding binding = new Binding("Text", dataset, "one.Text"); textbox.DataBindings.Add(binding); textbox.Width = 150; textbox.Height = 50; textbox.Top = 50; textbox.Left = 50; textbox.Parent = this; this.Controls.Add(textbox); I hardcoded the size and placement of the text box, but I can easily get that from the xml as well. I encountered a problem when I tried to pull TextAlign from the xml file though. I know that this would require the use of Format, so I implemented that. I changed the xml from above to look like this: <?xml version="1.0" standalone="yes"?> <SettingsData> <one> <TextAlign>Center</TextAlign> </one> </SettingsData> And I changed the code from above to look like this (changed from Text to TextAlign, and added the convert event handler): DataSet dataset; dataset = new DataSet(); dataset.ReadXml(@"d:\development\bindtest\form.xml"); TextBox textbox = new TextBox(); Binding binding = new Binding("TextAlign", dataset, "one.TextAlign"); binding.Format += new ConvertEventHandler(FormatHorizontalAlignment); textbox.DataBindings.Add(binding); textbox.Width = 150; textbox.Height = 50; textbox.Top = 50; textbox.Left = 50; textbox.Parent = this; this.Controls.Add(textbox); I also added the Convert Event Handler: public void FormatHorizontalAlignment(object sender, ConvertEventArgs cevent) { switch((string)cevent.Value) { case "Center": cevent.Value = HorizontalAlignment.Center; break; case "Left": cevent.Value = HorizontalAlignment.Left; break; case "Right": cevent.Value = HorizontalAlignment.Right; break; } } This event handler looks right to me. I followed the example from the help files. I've made similar code work with other data types such as booleans being coverted from a T or F in the xml file. DesiredType shows HorizontalAlignment. When I run this code, oddly, the event handler is executed three times. Each time seems to execute correctly. Then I get an unhandled exception from the Application.Run(new Form1()); Error creating window handle. Can anyone tell me what's happening and how to fix it? I foresee I'll have the same problem trying to read the font name and size from the xml file. I have a workaround, but it's very unelegant. Here's the stack trace: System.ComponentModel.Win32Exception: Error creating window handle. at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams cp) at System.Windows.Forms.Control.CreateHandle() at System.Windows.Forms.TextBoxBase.CreateHandle() at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl() at System.Windows.Forms.Control.WmShowWindow(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.Form.WmShowWindow(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.SafeNativeMethods.ShowWindow(HandleRef hWnd, Int32 nCmdShow) at System.Windows.Forms.Control.SetVisibleCore(Boolean value) at System.Windows.Forms.Form.SetVisibleCore(Boolean value) at System.Windows.Forms.Control.set_Visible(Boolean value) at System.Windows.Forms.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at bindtest.Form1.Main() in d:\development\bindtest\form1.cs:line 109 tia, brian Tag: Crystal Reports Problem: Please reply ASAP Tag: 65336

    - Panel Control Question I am stuck on something that must be simple. However, I have been searching the obvious places for several days but haven't come up with an answer: I have a Panel control with a custom designer. The designer creates several designer verbs. When a verb is selected, I want to instantiate a new Panel control on the 'base' Panel control, and allow the designer to edit the new Panel control (i.e., add other controls). The designer verbs work fine. However, if I simply use .Add to add a new Panel to the 'base' Panel the newly added Panel shows up on the UserControl but cannot be edited. On the other hand, if I simply drag a Panel control from the Toolbox to the 'base' Panel I can edit it--which is the behavior I want. The correct way to accomplish so it works this would be much appreciated! Tag: Crystal Reports Problem: Please reply ASAP Tag: 65332

    - Forms designer bug Hi I have a simple base form from which I want to inherit the Icon. When I create an inherited form based in this base form, with no added controls, the Icon shows correctly. When I add any control to the form, the designer creates also a resource for an Icon (null icon) and overrides the base form Icon definition. I can correct this behavior manually commenting the me.Icon line, but every time a change a property on any control of that form, the Icon is replaced to a null Icon It is a Bug of the forms designer?

    - Expamding empty ComboBox problem I have noticed the following problem. If you try to expand the drop-down list of a ComboBox (DropDownStyle=DropDown) with no items and immediately attempt to click another control (displayed underneath the combo box, not sure about other locations), nothing will happen. It takes several mouse clicks before you are finally able to select other dialog controls. My guess is that the combo box gets expanded, but since there are no items, the user does not see the list box portion of it, so if the user tries to click a check box, a button or some other control, this mouse click is obstructed by the expanded (but not visible) list box (this is just a guess, so it may happen for a totally different reason). This is very confusing for the customer, because it appears like the dialog is hanging (i.e. there is no response to the mouse clicks). Is this a known issue? Is there a workaround?

    - Building My Own DataSource Control hi All, I'm hoping to build my own datasource control, and hoped that someone would point me in the right direction to start. I have already created a class, which accepts a form, a tablename, a connection and a collection of field object (which contain information about which field binds to which form control). I build all this in code, and then the class gets a dataset, binds the controls to it, and allows modifiaction and updates etc. then saves them back to the database. However, I'd like to build a control, which would automate all of this, by getting the fields at design time, and allowing the user to bind the fields and then the user could simply change the connection string at run-time to point to the correct database when deployed. I am trying to kind of replicate the method by which you build bound forms in access. Any pointers to articles, or advice is greatly appreciated.

    - Licensing an assembly with components We are developing an assembly that will expose a multitude of components and controls. Many of them are inherited from one another and some of them represent user controls that group some other controls on them. We need to license all major types. We created a LicenseProvider that works very well by checking the design time license and embeding the runtime license in the result assembly. The problem is that if a user uses a large number of controls a separate license for each type gets embeded in the result making the file larger than needed. Also, the process of running the license check for each type might decrease performance a little. So, my idea was this: to create a special class inside the assembly with a static constructor. This means that everytime the assembly is loaded in one app domain the static constructor will be called. I would then run the license check in the static constructor and set a static value to true or false meaning the license was good or not. Then in each type I can simply check the static value and continue or not. Then, in the end result assembly only one license, corresponding to the special class, will be embeded... Considering that all other security issues are taken care of (sigining the assembly, etc...), does this method present any danger? Can anybody think of any security issues? This assembly will be sold entirely and there will be no licenses per type, but just per the entire assembly so this approach makes sense to me... I was only wondering if anybody might think of a reason why this might not be a good idea Thank you! Iulia Tag: Crystal Reports Problem: Please reply ASAP Tag: 65273

    - Legacy Application Reengineering (Basic to C#) We currently have a financial application running on an HP 3000, written in Basic ( the old kind, with line numbers and single-character variable names, etc) with about 500K lines of code. It uses a no-longer-sold, non-relational, HP-proprietary database called Image. This application has many very happy customers, each utilizing it via terminal emulator software in remote locations. We are tentatively architecting a phased migration to a .NET solution, for obvious reasons. Likely, we would first create a cleaner presentation layer based on WinForms, then migrated business logic off the HP3000 to a Win 2003 server ( in C# code), and finally move the database to SQL Server. But.. none of us have experience with a legacy migration/reengineering process (particularly from such an antiquated code base.) Further, given our meager start-up funding level, we cannot afford to hire expensive consultants who specialize in this area. Does Microsoft provide resources with advice on the reengineering process? Whitepapers? Web resources? tools? Also, would anyone recommend good books on this topic? Or any other websites (other than just Microsoft's)? Are there conversion tools to convert Basic to C#? And, my MOST IMPORTANT question (pardon the all caps)... are there "rules of thumb" for estimating programmer resource requirements for migration based on lines of code, database schema complexity, etc.?

    - SYNCHRONISING ALL OPEN FORMS - WINFORMS I have a client-server application using ADO.NET datasets where the user can open several forms - and as many copies of a form as they care to - and edit the data on them. How do you synchronise all the open forms when the user changes a value on the currently active form? For example: * user opens a ViewOrders form which shows a list of Orders including the SupplierName for each Order * user opens EditSupplier form which shows a list of Suppliers * user edits a SupplierName The corresponding SupplierName on ViewOrder form should now change to reflect the edit. I need a general pattern for this - there are hundreds of possible fields the user can edit and any number of different forms could be open - any of which may (or may not) need to be "synchronised".

    - WinForms app passes DataSet to remoted type: possible bug Our DAL (Data Access Layer as a dll) is hosted by IIS. We use binary serialization to pass a DataSet into the DAL from a client exe. Our client exe calls GetChanges on DataSet and passes the changes to our remoted DAL. On inserts we have an output parameter for the primary key. After the call to DataAdapter.Update, we watch the insert sproc run and return the output param value. We watch the DataRow change from Added to Unchanged. We watch the source column for output param get set to the outparam's value. The DAL then returns the DataSet to the client exe. Once back in the client exe, the DataRow is still marked as Added and the source column is empty. This is exactly the way it looked when it was sent to the remoted DAL. Now, if we run the DAL locally in a private folder, we see the same results in the DAL. However, back in the client exe the DataRow is marked as Unchanged and the source column contains the output parm value. This leads me to believe there is a bug in the Remoting or ADO.NET architecture. Tag: Crystal Reports Problem: Please reply ASAP Tag: 65248

    - PropertyGrid not updating correctly Hi, I've made a class containing a public int and a public Point. I also created a TypeConverter (in fact an ExpandableObjectConverter) supporting InstanceDescriptorInfo. This results in a nice expandable property containing the integer property and an expandable Point property. So far so good. Further I've found out that in order to inform my control that a sub- property has been changed then I have to override GetCreateInstanceSupported and CreateInstance. Now the control catches the updates. However: If I expand the property in the PropertyBrowser like this: -MyClassProp - PointProp X Y IntProp and then enter a new X value and press Enter then the PropertyGrid somehow gets confused and displays something like this: -MyClassProp + PointProp IntProp Y IntProp Ie. the Point-property is collapsed but still partially drawn as expanded! Collapsing and expanding the MyClassProp updates the PropertyGrid. My implementation of CreateInstance is pretty simple: public override object CreateInstance(ITypeDescriptorContext Context, System.Collections.IDictionary PropertyValues) { Point p = (Point)PropertyValues["PointProp"]; MyClassProp mcp = new MyClassProp((int)PropertyValues["IntProp"], p); return mcp; } What am I doing wrong?

    - WinApp Deployment Hello All, I am frustrated with the concept of No-Touch Deployment. This was a big marketing aspect of the .NET development model, but there are many ways to do it, and none of them are working for me. The Updater Application Block requires BITS, its own service, a script file, etc. This is a deployment issue to begin with. The 'navigate to an '.exe' file doesn't seem to work on my W2K3 Server, through an ISA firewall. (no idea where the issue is, just nothing happens when I navigate to the URL from my network. It works on the server itself. The server is in my Trusted Zone. I don't want to go opening huge holes without knowing how to approach this). Will W2K3 Server server the EXE over the net by default? Is my ISA Server preventing it? When I do run it on the server itself, I then get security issues related to the fact that my app hits a web service. Is this an effective means of deploying an application that will need to hit the user's hard drive, as well as a database / web service? How would I go about implementing it? Or, am I better to use the Updater Application Block? I have not found any article that details the security side of this, How To, Best Practices, etc. Just a few articles that make it sound so simple.

When I create the Databound Form and use a Textbox for the Date Field, the Form Fills properly, and I am able to modify the data. However, when I Change the Date Textbox to a DateTimePicker Control, with IDE Generated Databinding. The MileageRate Field, and any other Databound controls on the page become unbound. Any Ideas?

    - when to call dispose()? Hi, I have a form containing controls, a timer, and the EventLog component. I also create some new instances of classes that do not implement idisposable I don't want to leave the tidying up to the GC so... Do I need to explicitly call EventLog.dispose() as in the following snippet? protected overloads sub dispose(byval disposing as boolean) if disposing if components is nothing then components.dispose end if call MyEventLog.dispose(True) <<<-- end if end sub Also how do I make sure that the classes that don't implement idisposable return their memory one I've finished.Do I just close them, or set them to nothing, or what? Help much appreciated Tag: Crystal Reports Problem: Please reply ASAP Tag: 65200

    - Crystal Reports: Database connection problem. Highly Urgent Hello All, I have a windows application that is using Crystal reports. The database for the application is located on a different machine than the machine on which the application is running. Currently, we are using the IP address of the database server in the DB connection string. But when the user tries to pull up the reports, there is a request for the login information for the database server. I am completely at a loss to understand as to why this is happening. If anyone can provide any pointers towards this issue, it would be greatly appreciated. Thanks Mithun. Tag: Crystal Reports Problem: Please reply ASAP Tag: 65197

    - Solved: Microsoft Help: IEExe.exe and STA Hi. Thanks for all suggestions. I have finally solved the problem. The System.Windows.Forms.Timer fails because of the UI-operations it executes in my program. So the program crashes when it is being closed. The solution was to replace the System.Windows.Forms.Timer with an implementation of SetTimer and KillTimer. Now it works fine. ... int monitorTimer = SetTimer(this.Handle, 9999, 1000, 0); ... /--- Set timer [System.Runtime.InteropServices.DllImport("user32.dll")] extern static int SetTimer(System.IntPtr hWnd,System.UInt32 iEvent,System.UInt32 iElapse, int iCallbackMustBeZero); //--- Kill timer [System.Runtime.InteropServices.DllImport("user32.dll")] extern static int KillTimer(System.IntPtr hWnd,int iEvent); //--- Timer static static int WM_TIMER = 0x0113; protected override void WndProc(ref Message m) { //--- Check if it is a timer process if (m.Msg == WM_TIMER) { ) base.WndProc(ref m); } br/ peter Tag: Crystal Reports Problem: Please reply ASAP Tag: 65188

    - Problems binding control data types to a dataset I've run into a problem with binding form properties to data in an xml file (through a dataset). As it turns out, I can easily bind if the data type of the property on the control is a normal datatype such as a string or integer. If the datatype is not one of the built-in types however, things go horribly wrong. Consider this xml file: <?xml version="1.0" standalone="yes"?> <SettingsData> <one> <Text>Center</Text> </one> </SettingsData> If I create a normal winforms application and add the following code to the form's constructor, it works. I get "Center" in the text box. Here's the code that works: DataSet dataset; dataset = new DataSet(); dataset.ReadXml(@"d:\development\bindtest\form.xml"); TextBox textbox = new TextBox(); Binding binding = new Binding("Text", dataset, "one.Text"); textbox.DataBindings.Add(binding); textbox.Width = 150; textbox.Height = 50; textbox.Top = 50; textbox.Left = 50; textbox.Parent = this; this.Controls.Add(textbox); I hardcoded the size and placement of the text box, but I can easily get that from the xml as well. I encountered a problem when I tried to pull TextAlign from the xml file though. I know that this would require the use of Format, so I implemented that. I changed the xml from above to look like this: <?xml version="1.0" standalone="yes"?> <SettingsData> <one> <TextAlign>Center</TextAlign> </one> </SettingsData> And I changed the code from above to look like this (changed from Text to TextAlign, and added the convert event handler): DataSet dataset; dataset = new DataSet(); dataset.ReadXml(@"d:\development\bindtest\form.xml"); TextBox textbox = new TextBox(); Binding binding = new Binding("TextAlign", dataset, "one.TextAlign"); binding.Format += new ConvertEventHandler(FormatHorizontalAlignment); textbox.DataBindings.Add(binding); textbox.Width = 150; textbox.Height = 50; textbox.Top = 50; textbox.Left = 50; textbox.Parent = this; this.Controls.Add(textbox); I also added the Convert Event Handler: public void FormatHorizontalAlignment(object sender, ConvertEventArgs cevent) { switch((string)cevent.Value) { case "Center": cevent.Value = HorizontalAlignment.Center; break; case "Left": cevent.Value = HorizontalAlignment.Left; break; case "Right": cevent.Value = HorizontalAlignment.Right; break; } } This event handler looks right to me. I followed the example from the help files. I've made similar code work with other data types such as booleans being coverted from a T or F in the xml file. DesiredType shows HorizontalAlignment. When I run this code, oddly, the event handler is executed three times. Each time seems to execute correctly. Then I get an unhandled exception from the Application.Run(new Form1()); Error creating window handle. Can anyone tell me what's happening and how to fix it? I foresee I'll have the same problem trying to read the font name and size from the xml file. I have a workaround, but it's very unelegant. Here's the stack trace: System.ComponentModel.Win32Exception: Error creating window handle. at System.Windows.Forms.NativeWindow.CreateHandle(CreateParams cp) at System.Windows.Forms.Control.CreateHandle() at System.Windows.Forms.TextBoxBase.CreateHandle() at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl() at System.Windows.Forms.Control.WmShowWindow(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.Form.WmShowWindow(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.SafeNativeMethods.ShowWindow(HandleRef hWnd, Int32 nCmdShow) at System.Windows.Forms.Control.SetVisibleCore(Boolean value) at System.Windows.Forms.Form.SetVisibleCore(Boolean value) at System.Windows.Forms.Control.set_Visible(Boolean value) at System.Windows.Forms.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at bindtest.Form1.Main() in d:\development\bindtest\form1.cs:line 109 tia, brian Tag: Crystal Reports Problem: Please reply ASAP Tag: 65186

    - No Touch Deploy creating EMF's problem Hi, I have a No Touch Deploy application that I want to create and EMF File and serialize it back to the Server via Web Services. When I test the client application running from a local directory (MyComputer zone) it works fine. But when I launch with NTD from my web server I get a Security Exception in the CTOR of the emf. Is there anyway around this. I have tried several of the different CTORs available and the all have thrown the exception. It doesn't make sense that Creating a metafile would be a security violation. I am using the CTORs with a Memory Stream for saving to, so it isn't a FileIO Security issue. Thank You, -- Paul Tag: Crystal Reports Problem: Please reply ASAP Tag: 65179

    - CheckedListBox and ItemCheck Event Is there an event similar to ItemCheck, within the CheckedListBox class, that is called after a list item is checked and updated with the new check value? I currently have a method that iterates through the CheckedItems collection of a CheckListBox control. My problem is the CheckedItems collection doesn't have the correct count because of the ItemCheck event occurring before the checked state is changed.

    - weird bug on buttons I created 2 buttons and in the .Text property in teh designer I set one to "load..." and the other to "save..." The "load..." button was fine but the save button was displayed as "... save" on the form with the eplipses BEFORE the text, but the property for .Text was AFTER the text. Really odd.

Hello All,
I have a Windows application that uses Crystal Reports 9 (bundled Version)
developed using VS.NET 2003 on a windows server 2003 m/c.
The application has to be deployed on the client machine that has Windows
XP installed. Before deploying we make sure that .NET framework 1.1 is
installed on the XP machine. In the setup project, for support for Crystal
Reports, we have added the following merge modules:
1)Crystal_Managed2003.msm
2) Crystal_Database_Access2003.msm
3)Crystal_Database_Access2003_enu.msm
4)Crystal_RegWiz2003.msm
5)VC_User_CRT71_RTL_X86.msm
6)VC_User_STL71_RTL_X86.msm

The problem we are facing is like this: Whenever the user tries to pull up
the reports, a database logon screen pops up for the report. I am unable to
figure out as to why this is happening only for Crystal Reports. All the
other functionality in the application is working fine without having to
specify the database connection information interactively. The database
server is not in the same network as this Client WinXP machine. We specify
the IP address of the DB server in the DB connection string. Could this be a
problem?
If someone has faced this problem earlier or has any solution to this
problem, do let me know. I need to resolve this problem ASAP.

Thanks in advance
Mithun
