Open another Form from my Main form using a button click


Hi All


I have seen this question asked and answered several times but it doesn't seem to be the question. I have.


I have just created a new project I renamed form1 to FrmMain and then I created a new form by clicking add new form and I named it Report


I then went to my FrmMain and dropped a button on there from the toobox. I now need to open Report.cs when I click the button.


I have tried               Report Form2 = new Report();



But all that does it open a new FORM and its not my Report Form. It also just keeps opening new forms every time I click the button. My thought is that the user will enter a ID then click the button then the report form will open and I will then create a query to populate a data gride or view using the ID form the text box on FrmMain.


Please help.... I am new to this so shoot it straight as if this was your first forms application that you created.



Reg: Turn on more accessible mode & Skip to main content link message on Infopath2007 browser form



I have a infopath 2007 browser enabled form with c# code behind . The Infopath form is embeded\hosted in to a custom layouts page (.aspx) on MOSS 2007. The issue is when users use keyboard to fill the form, they often use <TAB> & <Enter> keys. So when they are using the tabbing at one location in the form, I have a "Contact selector" field, I enter a name & then hit <TAB> key the focus now comes to "name cheker" I then hit <Enter> key, I hit <TAB> again, the focus now comes to a button named "Accept", I hit <Enter> key & a filed below is populated with the values from user profile service. Now when I hit <TAB> I expect the focus should now come to that automatically populated field below the "Contact selctor". Because Infopath assings the tab order by default form top to bottom & left to right and I havent changed that default tab order.   

But, the focus moves to top of the webpage with a clickable link to "Turn on more accessible mode" I hit tab one more time & the link on top changes to "Skip to main content". This bheaviour does not seem to be happning in other form controls when they hit <Tab>, <Enter>. There are couple of areas on the infopath form where I have such a controls (layed ou

Delphi Win32 MDI Parent with C# Windows Forms child form

I have created an assembly containing a form that i want created as a MDI child form in a Delphi Win32 application's MDI parent control. I can create the .NET form fine from my Delphi code. I can even use the Delphi window handle to let my .NET form be a child in the Win32 application by using the SetParent API. However minimizing the child form makes it disappear (instead of the regular minimize action for MDI children), and it also doesn't cause the MDI container to get scroll bars when you drag the child form under the edge of the MDI container. I have the feeling that the child form is not yet correctly aware that it is a MDI child. For instance, its MdiParent property is null. And i read somewhere that i might need to call some more Win32 API"s to hook everything up correctly. I can't, however, for the life of me not find which ones to call, and where to do it. Is there anyone here that is well versed in hooking up managed Windows Forms with native Win32 applications that can lend a helping hand?

Not able to open workflow task form

I have a workflow created using SharePoint Designer 2010. This workflow has 'Collect Data' task. When the workflow is run, a task is created in the task list, however users can not open the task from the list and get the following error. There has been an error while loading the form. A form template (.xsn) file can not be accessed. You may not have the required permissions to open the file. The users who are trying to open the task have full control on the task list as well as the list from where the workflow is started. Site Collection Administrators are able to open the task. I am not sure at which place the users dont have permissions that they are not able to open the task.Tarun

Forcing web browser form version to open in emails

Form that is part of workflow wont open in form library


I am having an issue with my form. I have created a sharepoint sequential workflow using visual studio and as a task the user has to fill out an infopath form. When the form is submitted as part of the workflow is then saved to a form library. My issue is when I try to open the form in the form library I get the message "The form has been closed". 

I have check the Central Admin/Manage Form Templates and my form is here, status="Ready" and workflow enabled. But my form doesnt exist in the sitecollection/FormTemplate library. So I believe that when I try to open the form in the browser that template cant be found. Why I say that is when I open the form with the info path client, I get the message "The form was created with a new version of the form template. InfoPath cannot find the new version. Do you want to open with an older one" 
If a infopath form is part of a workflow and it be saved in a form library and then open, if so how?
Am I publishing the form incorrectly - I publish to network location. Then install my feature.
Do I need to associated the form template with the form library or should the feature installation take care of this?


- FormTemplate Library doesnt appear in site settings, I

InfoPath cannot open the selected form


I have been working on an InfoPath 2007 form for a week. It is actually a form I started from scratch to replace an existing form that had some weird stability issues for which there was no hope of a fix. The new form was working and previewing great until this morning when, for no apparant reason, it decided to start giving me the infamous "InfoPath cannot open the selected form" error when run from Visual Studio.

I clicked the "Was this information helpful?" link and responded "No", so I am sure that Microsoft has its best people scrambling for a fix; however, in the meantime, has anyone ever actually successfully fixed this error without starting over when clearing the cache (http://msdn.itags.org/microsoft-office/78856/) doesn't help?
