    - DateTimePicker I have a DateTimePicker on an Add/Edit Form... When the form is loaded the DTPicker is assigned Now in a ShortDate Value if Adding, or the ShortDate from SQL Server when Editing. When Adding, any date can be selected and works as expected. But, When editing I can only change the date by entering text in the DTPicker. I cannot click on a day, month, etc. from the dropdown - the value does not change. Tag: save winform and data Tag: 91326

    - Send data to form during intense method. Hi all, I have a form in a VB.NET windows application that, when a button is clicked, runs a pretty intense database process which can take up to ten minutes to finish. While it's running, I would like to be able to send data to the form so that the user knows the the application is still running. In ASP.NET, I would run this method in a new thread, and then simply update the form occasionally with data from the application. Is the approach in a windows application similar? And help and/or pointers would be greatly appreciated. Thanks, Wade Tag: save winform and data Tag: 91320

    - C++ Forms Graphs Charts "How to" Background: I'm pretty new to C++, so don't bamboozle me with anything too technical. Also, my company is cheap, very cheap, and I have only got the standard version of Visual Studio C++. Problem: I am looking to create some charts/graphs on my user interface, developed using forms, something that acts like the performance graph on the Windows Task Manager. I just assumed that VS would have some sort of graphing as part of their forms toolbox, this doesn't appear to be the case. I've looked on newsgroups and various support pages, but with no avail. Does VS have a graphing capability, and I'm being a bit thick? Or do I have to get some third party toolbox to do it?? Tag: save winform and data Tag: 91306

The Code below executes through each step. But the Controls don't refresh their displays to the corresponding text? - As you can se I tried calls to Refresh and Update against the control and its parent Form. These controls refresh OK when updated as a consequence of Button events in the Form itself. So am I missing something wrt threads and callbacks and controls refresh ?

    - SplitPostion during Form Load event I'm trying to save and restore a window position that has a splitter in it. When I close the app, I save the splitter's current SplitPosition, but when I reload that durigd the Form Load event, the splitters overrides what I tell it. Whenever I try to set a splitter's SplitPostion during the form load, is tries to rethink what I meant, enforcing the MinExtra value, even though it doesn't make sense until the Form is displayed. The code all works fine if I put it behind a button, after the form is already on screen. Any thoughts? Is this a bug in the framework, or do I need to do a layout trick? Thanks.

    - Converting RTF I have an Access app/db with a memo field that contains RTF (from a rich text control on a form in the app). I have a C#/Windows Forms app that I need to take the RTF text and convert it to "normal" text. If I lose things like bolding, italics, I don't care. I'm really just interested in getting the raw text out of this. Also, there are no images in the RTF. The only reason RTF was used was so users of the Access app could markup the text where emphasis was needed (e.g. bold, italize). I thought I could use a RichTextField control to do this for me. I would pull out the RTF contents from the Access db (via ADO.NET) and set the rtf property on the RichTextField control. Then I would use the text property of the RichTextField to get the raw, clean text. Well when I try to assign the RTF contents from the Access db directly to the rtf property I get an ArgumentException where the message is "Invalid file format". Any ideas what could be causing this?

    - app to use ftp to download a file I created a windows app written in vb.net that uses a shell command to use ftp to download a file. It works fine. I want to pipe the results of the ftp to a text file to analyze for errors. I can't get that part to work. If I do ftp by hand at a command prompt this works: ftp -i -s:ftpcommands.txt > ftpresults.txt This uses the commands in ftpcommands.txt to download a file and it pipes the results from the ftp to ftpresults.txt. When I try to do the same thing in vb.net code, it doesn't pipe the results to the file. I don't get any errors or anything. There's just no ftpresults.txt file there. I'm doing all this in the same directory that works using the command prompt directly.

    - Need Help This is the description of my problems. I used three ways to develop irregular-shaped WinForms : 1. Firstly I set the form's FormBorderStyle property to None. I set the form's BackColor property to Color.Black and the Transparent key property to the same color, then I drew the form's background using Graphics.DrawImage Method. 2. Like Method 1, I first set the form's FormBorderStyle property to None, then I changed the form's Region property. I built the region by building a GraphicsPath Object from a background Bitmap I used in the application and stored it in my assembly to use it in the future. 3. I used a different way to draw the window. I drew the background image by using Win32 Function UpdateLayeredWindow and set the form's style to LayeredWindow. I got different results on them but none of them satisfied our requirements. a. By using the first method, I could draw the form fast but there was black margin around the shape and when I change the background Bitmap in runtime the screen would flicker even though I had used DoubleBuffer. b. For the second method, the flickering shrinks a lot, but the process of dragging the window cost a lot of system resources and there was still a black margin around the Bitmap object. c. The last method maybe the best of all, and the margin disappeared , the problem of resource consumption did not exist, the window didn't flicker any more. But there was a big problem on it : the controls on the form just "disappeared" but still could be used when I click the controls' region(or area), the system just ignored the images of the controls. The last solution seems fit us well and I want to know if there is some way to eliminate the problem of the last solution and make my controls visible. Or if can not, how can I do to improve the performance of solution 1 and 2? That's it. Great thanks. Tag: save winform and data Tag: 91239

    - report solution suggestion Hi It's a windows application and internet connection is not always available for users. The data is saved locally. I am thinking about using XML file because there is not much data involved. For report, we can use Crystal Report. For .net it should be 10.0 version and above, right? Other solution can be ActiveX report. The downside is it's not managed code. I have thought of use XSLT and XML to create html file and load report in browser. However I am not sure if there is any hidden problems for example, the format of the report is not rendered exactly for each user because he may set the font size differently. Is it a concern?

I have a windows forms application that is running on a server and is invoked from client computers by using url remoting (the application assembly has been given execution permissions by using the Microsoft .NET Framework 1.1 Configuration tool). The application gets data from a database by mids of a web service. When it comes to generate a crystal report, if the application is launched locally (on the server machine) the crystal reports are loaded correctly, but if the application is launched from a client computer by the url (e.g. "http://192.168.10.11/MyApp.exe"), then one of the crystal reports(not all of them) shows a pop up dialog box to enter database login information such as "user name", "password", "server name" and "database name". I was debugging it, and it comes out that there is no connectivity with the crystal report object that feeds the crystal report viewer. This problem ONLY comes out when the application is launched remotely. I hope you can help me out pals. I think the problem is due to the report viewer..this object seems to love working locally...

Thus as near as can tell, if you want to exactly match column dat for date 1/1/2005 regardless of the time you have to write dat>= '1/1/2005' and dat<'1/2/2005'. Is this correct????

    - Offered functions of the run32.dll Hi guys I would like to play a little bit with the system menu of a window. I found already code that allows me to add items to the system menu. It uses a function from the run32.dll. I am sure that there are other interesting functions but I really do not know where to search for it. Do you know where I can find the definition of the run32.dll or how I can easily extract this information from the dll itself? Thanks in advance for your answer.

    - Trying to bind to Visible or Enabled property of form control Hi, just a quick one. i'm trying to bind the Visible property of a control to a public property of the parent form. i.e. private bool _okToDoSomething = false; public bool IsOkToDoSometing { get { return this._okToDoSomething; } } /// then in initialisation this.buttonDoSomething.DataBindings.Add("Enabled",this, "IsOkToDoSomething"); i've read that binding can only occur if bound object implement IList (which the form obviously doesn't) - so is something like this possible? and if so how do I do it? -- TIA Sam Martin Tag: save winform and data Tag: 91202

    - Instanciate reflected form without constructor... I need to scan a directory full of .net assemblies and list all Form subclasses found in a grid. This part is easy using reflection. I then need to allow the user to double click and modally display the form. Obviously I wouldn't expect anything to actually work; I just want it to be visible. Just like what Visual Studio does when you design a form. Unfortunately I cannot guarantee that the forms have default parameter-less constructors and even if they did, I cannot guarantee that those constructors could be successfully invoked (could have some static dependencies, etc). So I can't simply instantiate them. Since the forms have been built using Visual Studio, they should all have an InitializeComponent method. What I really need to do is only invoke this. Is there an easy way to do this? If it was possible to create an AssemblyBuilder from an already compiled Assembly, then I could just add the parameter-less constructor (or remove the IL from an existing one) and disassociate all the event handlers. I'm thinking that I need to create a new in-memory form subclass and dynamically transfer the InitializeComponent IL from one to the other. How hard would this be? I know that the assemblies have not been obfuscated. Nathan Tag: save winform and data Tag: 91197

    - Posting a file to a web server from a winform, just like a File Input HttpControl Hi, I am currently writing a WinForm administration application for a web application I have. I was wondering how it would be possible to upload a file to the web server using http, just like I would on a webform using a HtmlInputFile control. I have a hunch that it would be possible, but I cant really figure out how. Does anyone have a clue as to how I would accomplish this? -- Thomas Due Posted with XanaNews version 1.17.5.9 "There is always some madness in love.

    - Hide Contextmenu in treeview I have a treeview with which I want to use a context menu for certain nodes to fill a memo property of the node. So when I add the nodes I set a property 'ItemNode' to either true or false. If the ItemNode is true I want the contextmenu to pop-up if not I want to prevent it from popping up. Here's my code which won't work... Private Sub ContextMenu1_Popup(ByVal sender As Object, ByVal e As System.EventArgs) Handles ContextMenu1.Popup Dim rClickedNode As InheritTreeNode Try rClickedNode = CType(treeMenu.SelectedNode, InheritTreeNode) If rClickedNode.ItemNode = False Then MsgBox("Memo's only available for items!") Me.Focus() Dim hWnd As IntPtr = GetFocus() SendMessage(hWnd, WM_LBUTTONDOWN, 0, 0) SendMessage(hWnd, WM_LBUTTONUP, 0, 0) End If Catch ex As Exception End Try End Sub Thanks in advance, Mike Tag: save winform and data Tag: 91194

How to save all the winform state and project data (which may come from
database) when user closes application before completing all the tasks
in order to open the application later on to continue the job, like
WORD or Excel?

Can serialization do? Are there sample source codes to use?

TIA
