Create A GUI For A Command-line Based Exe Called Psftp.exe?

Mar 20, 2009

In VB2008 I would like to create a GUI for a command-line based exe called psftp.exe which can be downloaded here and basic usage here.I need to be able to carry out commands on the fly for example...

On Click of Button1- Connect to host
On Click of Button2- Prompt for username
On Click of Button3- Prompt for password

As these commands all relate to previous commands, they need to be carried out in the same instance of the command prompt.I have tried using the attached solution from an older post however it just doesnt work when trying to connect to a host (it works perfectly fine when using the standard command prompt).I'd also like to read any outputs from the command-line so I can create events on errors thrown for example...

On Click of Button1- Connect to host
On Click of Button2- Prompt for username
On Click of Button3- Prompt for password

If command-line throws "Access Denied"- MsgBox(The password you have provided is incorrect)My alternative to this is to buy a SFTP .NET component .

DataRow Collection - Update Requires Valid Delete Command?

May 1, 2010

I'm going through a book which is teaching me some basic coding principles of the language. The current section is detailing how to set up a master child form using two tables linked with a foreign key. The master table is displayed as a number of text boxes, and below is a grid with the child table which shows related records to whatever master record you happen to be checking out. At the top of the screen are the default navigation controls that are added with the grid. The master table is named Person and the child table Book. They are linked using a foreign key and have cascade set up on them.

The book informed me of the code required under the save icon on the navigation control so that when it is clicked both tables will be updated as required. It is as follows:
If Validate() Then
'Make sure editing has completed on both master and child tables
Me.BookBindingSource.EndEdit()
Me.PersonBindingSource.EndEdit()
[Code] .....

I have double checked that the code matches that shown, so this should in theory work fine. But if I manually delete a record from the Book (child table) grid and then click the Save icon on the navigation bar it comes up with the error "Update Requires A Valid DeleteCommand when passed DataRow collection with deleted rows".

Why changes made are not permanently saved to the database? I gather that it's using a "copy" of the data in the database but how do I get the code/form to make changes to the actual underlying database records as well as just the copy? I find this system very unusual, if someone deletes a record in the application why would anyone want this to be just done temporarily?

Have A Column In The Datatable Called Amount And A Textbox Acting As The Filter Called Say Maxamount To Set It?

Feb 9, 2011

i was wondering if it possible to have a condition where lets say you have a column in the datatable called amount and a textbox acting as the filter called say maxamount to set it so the rowfilter when filtering the table will sum the number in the amount column until the number in maxamount is met, then stop and only return the rows where the total sum of the amount column is equal or less than the maxamount value, so i guess if the next row takes us over the maxamount it discards this row and returns the rows previous to it. is this possible using datagridview rowfilter or should i be loooking elsewhere to achieve this?

Form Called FrmPracDetails Which Is Built Up With A List View Called LvwColProc

I have a form called FrmPracDetails which is built up with a List view called LvwColProc. Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails. What I want to do is when you make changes on FrmColProcesing and Click the Save Button (which calls the Save function)the changes appear instantly on FrmPracDetails. Please note, FrmColProcessing will always be open next to FrmPracDetails. I have tried to put this code in the Save function present in FrmCol Processing as shown below, but it doesnt Refresh FrmPracDetails form. [code]

So I know I need to add a delete command, but how do I write this in code and do I write it in the saveitem click event? I guess I would because the app crashes when I click save to update the dataset.

Properties - Default Property Set Being Called Mysteriously Called?

Apr 2, 2012

I have the following line of code in my program:

JCL_History.Enqueue(JCL_History(I))


This JCL_History object is basically a Generic.List encapsulated in a wrapper and has the following method:

Public Sub Enqueue(ByRef value As String)
If Members.Contains(value) Then
Me.RemoveAt(Members.IndexOf(value))

[Code].....

In my testing I have 2 items in this JCL_History list. When I call that first line of code I posted (the one that invokes Enqueue) with I = 1 I expect the first item to be shuffled to the bottom and the second item to be shuffled to the top.

After the thread returns from Enqueue I notice that this is exactly what happens to my list, HOWEVER if I hit the "step_in" button after the execution of Enqueue I go into the Default Property's set method where Index = 1 and value = and it screws everything up, because the item that got shuffled to the end (index 1) gets overwritten by the item value shuffled to the top.

So basically the set method on the default property is getting called at what I think to be a completely ridiculous time. What gives? By the way I'm running VS2005 on XP.

.net - SSRS Report Called From ReportViewer Control Displays No Data In The Report When Called With A Parameter

Apr 11, 2012

Can you look at my coding and let me know what I'm missing or doing wrong?I have a SSRS report that is called from a ReportViewer control and the ProcessingMode for this control is Remote. The report also has 1 parameter in it's DataSet.In the code I placed a MsgBox to make sure the code is finding the parameter and returning the parameter name. I am trying to stick the value of 10 into the parameter for playerID 10. Data for this player does exist.

I believe I need to add some more code to make this work but I'm not sure what else to add.

When the code executes the report is displayed but no data is shown in the report.

I recently found an awesome tool called "Freemind" that is called a 'mind mapping' program. It's similar to MS Visio but way cooler and more automated.I reeeallly would like to integrate this into a VB.net Form, but how?

Has anyone seen or heard of mind mapping inside VB.net before? Are there programs out there already that work with VB.net or anyone have an example they have seen / built that works?
