I created an application for Windows XP, now it needs to run on Windows 7. I have had some issues to resolve, but rather small ones. I am now stumped on this one... Here is my code block

The code works perfectly for Windows XP, but the ftpRequest does not work in Windows 7 for renaming. That said, the code runs that entire sub becaues WriteToEventLog get's written, but seems to ignore the ftpRequest lines.
I have a very stubborn check box . Let me tell you its story :There is Form1 with a button leading to Form2 . On Form2 there is located that stubborn check box I was telling you about . That check box has code in its CheckedChange event and accordingly to its Checked condition , it enables or disables some text boxes .Well , the first time Form2 is shown , that check box works fine : when I check it it enambles the text boxes and when I uncheck it , it disables those text boxes .Then , I press the button to return to Form1 . If needed , the code in the button is :Form1.ShowMe.CloseMy adventure starts when I show again Form2 ... This time the check box is acting weirdly . No matter if I check it or I uncheck it , it always disables the text boxes , as if it is constantly unchecked ! I can see it changing its checked state whenever I click on it , but it always runs the code to disable the text boxes.
I even used some break points in the code and found out that indeed it is the code that disables the text boxes that is called every time , no matter if the check box is checked or unchecked .I don't thing this has anything to do with the fact that this event is called by all the 4 check boxes on the form . After all , it is always the 1st check box that causes the problem (I can see it when moving the cursor over the genericindex variable) .
With this code I can see what happening I'm just showing you what've I've done so far. Basically I want to use an If statement to see if an active directory object contains one of the keywords found in an INI file. I was wondering is this possible with just an IF statement or do I have to use a loop or a for each and how would I do that using one of those two. [code]
View 2 RepliesI am building a text editor kind of like Notepad++ and I would like to set up the color coder for key words such as And. I will be doing this for VBScript and Java.I would like the keywords to change when the file is saved for example, when the user loads a blank document nothing will be color coded but if the document is saved as .vbs the keywords for vbs will be blue and comments ' will be green.

I'm working on porting some classic VB6 code to C# and just stumbled across a usage of the PV function.I feels wrong including a reference to the Microsoft.VisualBasic Assembly. Is this something that is commonly done, or should I explore further options. The next idea that pops into my mind is exploring this PV function in Reflector.

View 5 RepliesI'm working on some legacy VB5/VB6 code and need to convert a ".bas" file to vb.net. i found several options
Compile the .bas file into a com dll and then reference and use it in my project. (For this I guess I would need vb5 or vb6 which I don't have at my disposal) Copy and paste the contents of the file in to a new module in vb.net and then try solving the errors one by one.The contents of the .bas file reference a particular dll. The .bas file has mostly declarations consts, types, sub's and functions.
What would be the most elegant way of redoing this in vb.net. Is it as simple as option 2.EDIT
I used VS2008 express and ran the code through the upgrade wizard it did the necessary conversion. and the .bas file was converted to .vb. I took that file and decided to rewrite other parts of the code, including some redoing of the converted .vb file. Other questions related to this one are here.
We are looking to port our existing classic ASP application to .NET, but we're unsure of what language to use for the new app. I personally would 'prefer' C#, as I'm more familiar and comfortable with that languages way of doing things, but, the original code is VBScript, so it would possibly be easier to port to VB.NET ... One possible situation I fear would be that, because the code is so similar between the two variants of VB, that we might end up getting stuck on something that is not similar between the two, even though it looks like it would work. A shift to a wholly different language might avoid that kind of situation. Does anyone have any practical examples of this kind of situation? Insights to illuminate the issue with? Do the potential benefits of a complete paradigm shift outweigh the gains from a high degree of 'copy-and-paste-ability' ?
View 9 RepliesI am porting a vb6 application to VB.net. One of the key forms has a large msflexgrid on it - about a 1000 columns and 50 rows. It has 2 header rows - the first header row has merged cells to form a main header and the second row has sub headings. There is no requirement for any data entry and it's unbound. The code does the work in deciding what to display (if anything) in each cell. It is solely used to display data in the form of a character and a coloured background and to display a tooltip text with more information when you mouse over it. Works beautifully in vb6. I'm trying to decide whether to:
a) use the vb6 msflexgrid in the .net version
b) use the datagridview - which at a first glance seems to have a problem merging the cells on the header row
c) build my own custom control to do the job
I've got a VB 6 application that I ported over to VS 2005. The application has a toolbar on it. When building it in VB 6, I created all the bitmaps for the toolbar. And they looked just fine.Now I have ported to VS 2005. The toolbar works just fine. But the images in the toolbar look "wrong". The best way to describe them is if you took each bitmap and squeezed it down to about 67% of it's size. So it is missing the detail it used to have. And the smalleer picture still takes up the same amount of space on the toolbar. It is just that each squeezed bitmap now looks like it has a thick, blank pictureframe around it.

Please don't answer SQL Server! - this needs to be an app that end users can install easily in corporate or non-corporate environments, and must not require any ongoing technical maintenance.

I have a project where I want to have checked arithmetic by default, except for one performance sensitive spot. Unfortunately, VB.Net doesn't have an 'unchecked' block.Ideally the framework would have some sort of integer type with explicitly unchecked arithmetic, but I didn't find anything like that. I did find that expression trees have binary expressions for unchecked operations, but the delegate overhead cancels out the unchecked advantage (and then some).
Currently I'm converting the inputs to UInt64/Int64 before doing the arithmetic, then converting back (with a bitwise And to ensure in-range). It's about 50% slower than unchecked arithmetic (according to profiling).
Moving the arithmetic-sensitive part to a project with unchecked arithmetic might work, but it seems like overkill to give it an assembly all to itself.

I am using VB Stuido 2008, Net Framework 3.5.I have one Checkbox to Identify the record as Inactive if checked. When I load the form the checkbox is alway unchecked, which is what i want. However, when I go to add a new record the checkbox, not the text for the checkbox is always shaded green, not a checkmark. The checkbox then reacts as if it is checked. This makes it necessary to uncheck the checkbox or else all my record react as if checked.
in the table defintions I have set the default binding value to ((o)) which = unchecked. Iafter setting the default value to ((0)) I deleted the checkbox from my form and then replaced. Not I still get the checkbox shaded which reacts as if Checked.
