example of saving picturebox as png no dll's please modules and classes only....
What have you done yourself, beside begging for complete solutions?
ouch that felt a little hostile why such hostility my bad bro i meant no disrespect by the ? i do apolagize for whatever i said ......... ill post my code im using tho i dont take credit for code i didnt write but all my debuging has done no good all i can think of is the stdpicture is my error being as that when debugged on the savepictur line it say in the function declarations the picture = nothing hence why im sure its saving as nothing ......... but what i find strange is the filename = "" but on down it does use the specified called filename from call for the function weird i thought but the type of fine is there in the function declartions as .png or whatever type im trying to save and yes my wording may not be proper i am self tought i have tryed to adapt and learn but im ok with code just some stuff ive never done i dont know how and as a self tought trial error and help is the only way i learn kinda like through repetition the more times i do the functions calls declaration the more i remeber them and understand how they work ... but ne ways to my code im trying to use........this is my module
this is how i call it which im sure is right .... cuz in the call the picture = 912808929 and the filname is ther and type is there just when i debug the function the filename doesnt show in its declarations it shows "" and the pict = nothing i use picture1 which is a picturebox perhaps i should have ref a wia.dll or somthing im not sure but seems like the picture1.image should be also 19808980 in this part as shown below and seems the filename would show but only the type shows pictype = ".png" there belowCode:Option Explicit

this is how i call itCode:SavePic(ByVal pict As StdPicture, ByVal FileName As String, PicType As String, _
Code:SavePic Picture1.Image, "C:\Test.png", ".png"
If you break on your function, on the "Public Sub ... " line, then hover over the parameter names, you should expect to see Nothing, "", etc for ByVal parameters. Once you press F8 to get to the next executable line, then the Nothing, "", etc should no longer be seen.Quote:
but what i find strange is the filename = "" but on down it does use the specified called filename from call for the function weird i thought but the type of fine is there in the function declartions as .png or whatever type im trying to save
Does that help for the next step in your troubleshooting?
As far as what is or is not being saved, does c:\test.png contain data? I'm guessing it does and your problem may simply be that Picture1.AutoRedraw = False?
And not intended to be hostile -- jeez Josh, sprinkle a bit more punctuation into those long posts :)
Given your recent questions I feel bound to ask, what is in the picture that you are trying to save? What is it a picture of?
Whilst reading this aloud to myself I passed out through lack of oxygen.Quote:

And we got both
how to save picture in picturebox? I input pic1 on picturebox.1, and pic1 is processed to change its pixel and change to pic2 in picturebox2. Then i use commondialog to save pic2. i'd use this code, but id didn't work.
Code:Private Sub save_Click()
CommonDialog1.ShowSave
If CommonDialog1.FileName <> "" Then
Open CommonDialog1.FileName For Output As #1
Write #1, outputgambar.Picture
Close #1
End If
End Sub

P.S. You can't save a picture that way. You may want to start your own thread on how to use VB's SavePicture function.
